FCC & Telecommunications Regulation

The Federal Communications Commission — an independent regulatory agency created by the Communications Act of 1934 (47 U.S.C. § 151) and substantially restructured by the Telecommunications Act of 1996 — regulates interstate and international communications by radio, television, wire, satellite, and cable across the United States. The FCC's five commissioners (no more than three from the same party, serving 5-year staggered terms) set rules governing spectrum allocation, broadcast licensing, broadband internet access, telephone networks, and consumer protection in communications markets. Net neutrality — whether broadband providers can block, throttle, or charge for priority access to websites — has been the FCC's most contested battleground for two decades: the Open Internet Order (2015) imposed Title II common carrier rules, reversed under the 2017 Pai FCC, reinstated under the 2024 Rosenworcel FCC, and challenged again in court. The FCC also administers the Universal Service Fund (USF) — collecting roughly $10 billion/year from telephone subscribers to subsidize broadband and phone service in rural areas, schools, libraries, and for low-income households (Lifeline). Section 230 of the Communications Decency Act, which shields online platforms from liability for user content, sits outside FCC jurisdiction but is frequently debated alongside FCC authority as Congress considers broader internet regulation.

How It Works

The FCC regulates virtually all electronic communications in the United States — telephone, broadband, radio, television, satellite, cable, and wireless — under a framework that has evolved dramatically from the monopoly-era Communications Act of 1934 through the competition-focused Telecommunications Act of 1996 and beyond.

Radio spectrum — the finite resource used by cellular networks, broadcast TV and radio, Wi-Fi, GPS, satellite, and public safety systems — is one of the FCC's most consequential regulatory domains. The FCC allocates spectrum bands for different uses, licenses spectrum through competitive auctions (which have raised over $230 billion since 1994), manages interference, and designates unlicensed bands where Wi-Fi and Bluetooth operate without individual licenses. Major recent auctions have targeted mid-band C-band and 3.45 GHz spectrum critical for 5G deployment. Whether and how the FCC regulates broadband internet access has been the most contested telecommunications policy question of the 2020s: the FCC has oscillated between classifying broadband as a Title II "telecommunications service" subject to common carrier regulation (including net neutrality rules prohibiting blocking, throttling, and paid prioritization) and as a Title I "information service" subject to lighter oversight. The Supreme Court's Loper Bright Enterprises v. Raimondo (2024) decision overturning Chevron deference has complicated the FCC's regulatory authority in this area.

The Universal Service Fund (USF), funded by assessments on carriers passed through to consumers as a line-item charge, supports four programs: E-Rate (~$4 billion per year for school and library internet connectivity), Lifeline (monthly subsidy for low-income consumers' phone and internet service), Rural Health Care (broadband for rural healthcare providers), and High-Cost (subsidies for carriers in high-cost rural areas). The Affordable Connectivity Program provided $30/month broadband subsidies to low-income households before its funding expired in 2024. On broadcasting, the FCC licenses radio and television stations, enforces content rules (obscenity, indecency, and profanity restrictions apply to broadcast but not cable or satellite), manages the transition to next-generation ATSC 3.0 television standards, and administers the equal time provision for political candidates. Cable and video regulation under Title VI covers franchise requirements, must-carry rules requiring cable systems to carry local broadcast stations, and retransmission consent allowing broadcasters to negotiate payment from cable operators. The FCC has also made combating illegal robocalls a major enforcement priority — implementing STIR/SHAKEN caller ID authentication, requiring carrier call blocking, and imposing substantial fines — alongside administration of the Telephone Consumer Protection Act (TCPA), which restricts automated calls and texts and generates significant private litigation.

  • Subpart FF — Cable Landing Licenses (18 sections): submarine cable landing license applications and processing; ownership and control disclosure requirements; national security conditions routinely imposed (DoJ/DHS/DoD "Team Telecom" review); license modifications; annual reporting

• 47 CFR Part 20 — Commercial Mobile Services: the FCC's foundational classification rule for commercial mobile radio service (CMRS), establishing the regulatory framework that applies to wireless carriers like AT&T, T-Mobile, and Verizon. Key provisions:

  • § 20.3 — Definitions: defines CMRS as any mobile service that is provided for profit and makes interconnected service available to the public (or a substantial subset); the definition determines which carriers face common carrier obligations under Title II of the Communications Act; private mobile services (e.g., corporate internal networks, dispatch systems) are not CMRS and face lighter regulation
  • § 20.11 — Interconnection: local exchange carriers (telephone companies) must provide technically reasonable interconnection to CMRS providers upon request; this ensures that wireless-to-landline calls work seamlessly — a regulatory requirement that established mobile phones as functional replacements for wireline service in the 1990s
  • § 20.12 — Resale and automatic roaming: CMRS carriers providing broadband PCS, cellular, and other specified services must offer automatic roaming to other domestic CMRS carriers on a technically feasible basis at reasonable, nondiscriminatory rates; the rule prevents carriers from stranding customers outside their home coverage area; roaming disputes may be brought as informal complaints to the FCC
  • § 20.13 — State authority over CMRS rates: states are preempted from regulating CMRS rates and market entry under Section 332(c)(3) of the Communications Act; however, states may petition the FCC for authority to regulate intrastate CMRS rates if they demonstrate market conditions fail to protect subscribers — a petition pathway that has been used rarely, as competitive wireless markets have made rate regulation largely unnecessary
  • § 20.15 — Title II obligations: CMRS providers must comply with core common carrier obligations under the Communications Act, including Sections 201 (just and reasonable rates), 202 (no unjust discrimination), 223 (obscene/harassing calls), 225 (TRS/relay services), 226 (operator services), and 228 (premium service rules for 900 numbers)
  • § 20.19 — Hearing aid compatibility (HAC): CMRS handsets sold in the U.S. must meet FCC HAC standards; manufacturers and carriers must offer a minimum percentage of HAC-rated handsets in their product lines; HAC ratings (M-ratings for microphone compatibility, T-ratings for telecoil compatibility) must be disclosed to consumers; the FCC's HAC rules for wireless handsets have been progressively tightened as the vast majority of Americans now rely primarily on wireless phones
  • § 20.22 — Mobile spectrum holdings review: applicants for mobile wireless licenses, license assignments, or transfers of control must disclose their spectrum holdings; the FCC reviews whether the transaction would create excessive concentration of mobile spectrum holdings in a geographic market; the spectrum screen analysis (40 MHz in sub-1 GHz, broader screens for combined spectrum) is the primary tool for reviewing wireless merger transactions
  • § 20.23 — Contraband wireless devices in correctional facilities: CMRS licensees must negotiate in good faith with correctional facilities seeking to deploy Contraband Interdiction Systems (CIS) to prevent unauthorized wireless use by incarcerated individuals; carriers must provide technical information needed to configure CIS; the rule reflects the growth of cell phone contraband in prisons as a safety and criminal enterprise concern

  Part 20's classification of wireless carriers as CMRS subject to Title II common carrier obligations was the legal foundation for treating mobile phone service as public utility-like infrastructure rather than a private closed network. The interconnection mandate (§ 20.11) and roaming requirement (§ 20.12) in particular shaped the competitive wireless market by ensuring that customers of any carrier could make and receive calls regardless of geographic coverage — creating the consumer expectation of nationwide roaming that wireless carriers now fulfil through network coverage and commercial roaming agreements.

• 47 CFR Part 24 — Personal Communications Services (53 sections across 9 subparts — the FCC's licensing rules for broadband PCS in the 1850–1990 MHz band, which is the primary spectrum underlying 3G, 4G LTE, and 5G cellular service from carriers like AT&T, T-Mobile, and Verizon):

  • Subpart A — General: § 24.1 establishes PCS as a flexible-use radio service; § 24.12 — any entity not precluded by section 310 of the Communications Act (foreigners owning more than 20% of a licensee) is eligible to hold a PCS license
  • Subpart E — Broadband PCS (16 sections): § 24.201 — broadband PCS licenses cover A–F frequency blocks in the 1850–1990 MHz band; § 24.202 — service area is a Basic Trading Area (BTA) or Major Trading Area (MTA); § 24.203 — construction/buildout obligations: C- and F-block licensees must provide substantial service within 5 years or risk license forfeiture; § 24.204 — partitioning and disaggregation allowed (geographic and spectrum sub-licensing); § 24.236 — power limits: 2 watts for portable handsets, 20 watts EIRP for base stations, 100 watts EIRP in rural areas
  • Subpart H — Competitive Bidding (6 sections): PCS licenses are awarded through spectrum auctions under Part 1 Subpart Q; designated entity (DE) provisions apply: small businesses bidding on C and F blocks receive 15–25% bidding credits; DEs must demonstrate they actually control and operate their licensed spectrum or face license cancellation — a recurring enforcement issue
  • Recent rulemaking: 90 FR 57705 (2025) updated buildout rules and flexible use provisions for residual broadband PCS spectrum to align with the Commission's 5G-era spectrum policy framework

• 47 CFR Part 22 — Public Mobile Services (127 sections across 8 subparts — the FCC's licensing and technical framework for three distinct commercial wireless services that predate modern PCS: the original cellular radiotelephone service in the 800–900 MHz band; paging and radiotelephone service (Subpart E); and offshore radiotelephone service (Subpart I) for oil platform and maritime workers):

  • § 22.5 — Citizenship: implementing Section 310 of the Communications Act, no Public Mobile Services license may be held by a foreign government, a representative of a foreign government, an alien, or a corporation in which more than 20% of directors or officers or more than 25% of stock is controlled by foreign interests; this alien ownership restriction applies to all Part 22 licenses
  • §§ 22.131–22.169 — General provisions for all Public Mobile Services: mutual exclusivity (§ 22.131 — when two applications for the same spectrum are mutually exclusive, the FCC uses competitive bidding); pre-construction coordination (§ 22.150 — on certain channels, carriers must coordinate proposed spectrum use with existing systems before filing; this reduces interference before authorizations are granted); additional transmitters (§ 22.165 — a licensee may add transmitters at new locations on already-licensed channels without new FCC authorization if technical conditions are met — reducing licensing burden for network expansion); emergency operation (§ 22.307 — licensees may operate during emergencies even when normal FCC procedures cannot be followed)
  • §§ 22.201–22.229 — Paging geographic area licensing (competitive bidding): paging area licenses are awarded through FCC spectrum auctions; small businesses (average annual gross revenue ≤ $15 million) receive a 30% bidding credit; very small businesses (≤ $3 million) receive 35% bidding credits (§ 22.217, 22.229); winning bidders may partition geographic service areas or disaggregate spectrum assignments to sell portions to secondary licensees (§ 22.513); paging geographic area licenses cover Major Economic Areas (MEAs) or Economic Areas (EAs) — the same area types used in PCS licensing
  • §§ 22.501–22.579 — Paging and Radiotelephone Service: paging channels are allocated in the 35/43 MHz, 152/158 MHz, and 929/931 MHz bands; the 929/931 MHz band is the primary modern paging spectrum (used by Spok, Ameritec, and other commercial paging operators); paging geographic area authorizations (§ 22.503) cover the licensee's entire geographic area rather than individual transmitter sites — enabling large nationwide paging networks to operate under a single license covering each geographic service area; one-year construction period (§ 22.511) to activate service; signal boosters allowed (§ 22.527) to extend indoor coverage
  • §§ 22.1001–22.1037 — Offshore Radiotelephone Service: the FCC allocates specific channels (in the 450–470 MHz band) for paired assignment to shore-based central stations and offshore subscriber stations on oil platforms, drilling rigs, and supply vessels; antenna height limitation (§ 22.1011 — shore stations may not exceed 61 meters/200 feet above sea level); priority of service (§ 22.1005 — the service is intended primarily for public message service, not private communications); 18-month construction period applies to offshore stations

  Part 22's cellular radiotelephone service (Subpart H — not detailed here, covering the 800–900 MHz cellular band originally awarded to duopoly licensees) and paging service (Subpart E) represent the FCC's first generation of commercial mobile wireless licensing. The 800 MHz cellular spectrum — awarded in the 1980s to two licensees per market (the wireline carrier and a competing applicant) through a comparative hearing process rather than auctions — became the foundation of the U.S. wireless industry. Today's AT&T, T-Mobile, and Verizon continue to hold and operate 800 MHz cellular licenses under Part 22 alongside their PCS (Part 24) and AWS spectrum. Paging remains a viable commercial service: medical paging (hospitals, doctors on call), industrial telemetry, and public safety backup communications still rely on Part 22 paging spectrum for its superior building penetration and wide-area coverage compared to cellular.

• 47 CFR Part 68 — Connection of Terminal Equipment to the Telephone Network (53 sections — the FCC's rules establishing the right of consumers to connect any FCC-registered terminal equipment to the public switched telephone network (PSTN); before Part 68 and the Carterfone decision (1968), AT&T prohibited connection of any customer-owned equipment to the network, claiming third-party equipment would harm the network; Part 68 ended that practice by establishing technical standards for safe connection, creating a private certification ecosystem):

  • § 68.1 — Purpose: protect the telephone network from electrical harm; ensure interoperability; protect telephone company employees and subscribers; facilitate use of hearing aids
  • § 68.100 — Any terminal equipment approved under Part 68 may be directly connected to the PSTN by the customer — no telephone company permission required; the customer's right to connect is absolute as long as the equipment meets the technical standards
  • § 68.102 — Approval requirement: terminal equipment must be approved by a Telecommunication Certification Body (TCB) recognized by the FCC (§ 68.160) or by the FCC itself for certain categories; approval involves testing to technical standards developed by the Alliance for Telecommunications Industry Solutions (ATIS)
  • § 68.105 — Demarcation point: the point at which the telephone company's network ends and the customer's wiring begins; telephone companies must provide a jack at the demarcation point; customers own their inside wiring and jacks (and responsibility for their maintenance)
  • § 68.106 — Notification requirement: customers must notify their telephone company before connecting terminal equipment that is not a standard registered device; this is the FCC mechanism by which telcos learn what is being connected to their network, even though they cannot refuse connection of approved equipment
  • § 68.108 — Harm incidence: if terminal equipment causes actual harm to the network, the telephone company may temporarily disconnect it upon providing notice; the telephone company must cooperate with the customer to resolve the problem; permanent disconnection requires a finding under § 68.110
  • § 68.112 — Hearing aid compatibility: all telephones at the customer premises (including wireless handsets used with wireline service) must be hearing aid compatible; coin-operated telephones must all be HAC-compliant; the Part 68 HAC requirements operate alongside FCC Part 6/7 accessibility rules for wireless handsets
  • Part 68 covers roughly 100 million PSTN connections and is the regulatory foundation of the entire consumer telephone equipment market — from simple corded phones to DSL modems to complex business PBX systems; the transition from circuit-switched PSTN to IP networks has raised questions about Part 68's continued applicability, as VoIP equipment connects through internet protocols rather than traditional RJ-11 telephone jacks; the FCC has addressed this through waiver proceedings and has proposed updated standards for IP-based terminal equipment

• 47 CFR Part 51 — Interconnection — the FCC's regulatory framework implementing Sections 251 and 252 of the Telecommunications Act of 1996, which created the framework for competitive local exchange carriers (CLECs) to access incumbent telephone networks. Key subparts:

  • Subpart B — Obligations of All Telecommunications Carriers (§§ 51.100–51.223): § 51.100 — every telecommunications carrier has a duty to interconnect directly or indirectly with other carriers' facilities and equipment; § 51.203 — number portability rules cross-reference Part 52 Subpart C; § 51.205 — local dialing parity: a LEC must allow customers to dial the same number of digits for local calls regardless of which provider they use; § 51.217 — nondiscriminatory access to telephone numbers, operator services, directory assistance, and directory listings; § 51.223 — only ILECs (incumbent LECs designated under § 251(h)) face the enhanced Section 251(c) obligations — a state commission may not impose those obligations on non-incumbent carriers without FCC authorization
  • Subpart D — Additional Obligations of Incumbent Local Exchange Carriers (ILECs) (§§ 51.301–51.321): § 51.301 — ILECs must negotiate in good faith on interconnection agreement terms; § 51.305 — interconnection duty: ILECs must provide any requesting carrier with interconnection at any technically feasible point in the ILEC's network at rates that are just, reasonable, and nondiscriminatory; § 51.307 — unbundled access duty: ILECs must provide nondiscriminatory access to network elements (the "UNE" obligation — local loop, transport, switching, OSS) on an unbundled basis; § 51.309 — ILECs may not restrict use of unbundled network elements for competitive service; § 51.311 — quality of access to UNEs must be identical to what the ILEC provides to its own retail operations (operational support system parity); § 51.315 — ILECs must offer UNEs in combinations and convert wholesale services to equivalent UNEs on request (§ 51.316); § 51.319 — specific unbundling requirements: local loops must be made available on an unbundled basis including the high-frequency portion of the loop for DSL co-existence; subloops (from a feeder distribution interface to the customer premises) must be unbundled where technically feasible; § 51.321 — three methods to obtain interconnection: (1) negotiated agreements, (2) arbitration before state commissions, (3) adoption of existing interconnection agreements from other carriers
  • Subpart E — Exemptions, Suspensions, and Modifications (§§ 51.401–51.421): rural and small LECs may petition their state commission for exemptions from unbundling obligations; state commissions may grant suspensions or modifications of Section 251 obligations if technically or economically infeasible in a specific situation
  • Subpart F — Pricing of Elements (TELRIC) (§§ 51.501–51.515): the most technically complex and litigated subpart — establishes the Total Element Long-Run Incremental Cost (TELRIC) pricing standard for UNEs; § 51.503 — rates must be just, reasonable, and nondiscriminatory; § 51.505 — forward-looking economic cost equals the sum of (1) the total element long-run incremental cost (TELRIC) — the cost a hypothetically efficient carrier would incur to provide the element — plus (2) a reasonable allocation of forward-looking common costs; § 51.507 — cost recovery must match how costs are actually incurred (flat rates for dedicated facilities, usage-based rates for shared elements); § 51.511 — forward-looking cost per unit is the total forward-looking cost divided by total expected units; § 51.513 — state commissions may use cost proxies where cost data is insufficient, subject to FCC-approved methodologies
  • Subpart G — Resale (§§ 51.601–51.617): ILECs must offer their retail telecommunications services for resale at wholesale rates (the retail rate minus avoided costs); § 51.607 — restrictions on resale are presumptively unreasonable; § 51.613 — wholesale discount rates are set by state commissions using an "avoided cost" methodology
  • Subpart H — Reciprocal Compensation (§§ 51.700–51.715): § 51.700 — these rules govern the transition from the historical calling-party's-network-pays model to bill-and-keep (carriers do not charge each other for termination of calls): § 51.701 — scope covers both interstate and intrastate traffic; § 51.703 — each LEC must establish non-access reciprocal compensation arrangements with any requesting carrier; § 51.705 — the default compensation rate for Non-Access Telecommunications Traffic exchanged between a LEC and a CMRS (wireless) provider is $0.0007/minute transitioning to $0 (bill-and-keep); § 51.711 — reciprocal compensation rates must be symmetrical unless carriers mutually agree otherwise; § 51.713 — bill-and-keep: carriers exchange traffic with no per-minute termination charges — the approach that replaced the old calling-party-pays compensation regime after the FCC's 2011 Intercarrier Compensation Reform order (FCC 11-161)
  • Subpart I — Procedures for Implementation of Section 252 (§§ 51.801–51.813): state commissions are the primary arbitrators of interconnection agreements — they receive, mediate, and arbitrate disputes; § 51.803 — a carrier requesting interconnection may file an arbitration petition with the state commission if negotiations are not concluded within 135 days of the initial request; state commission must resolve the arbitration within 9 months of the initial request; § 51.807 — state commission must approve or reject negotiated and arbitrated agreements within 90 days; § 51.809 — FCC retains authority to review state commission actions under Section 252 and can assume authority if a state commission fails to carry out its responsibilities (§ 51.320)
  • Subpart J — Transitional Access Service Pricing (§§ 51.901–51.915): rules for transitioning legacy interstate and intrastate switched access rates to the new intercarrier compensation regime over a multi-year glide path; carriers with rates above the applicable benchmark must reduce rates according to the schedule; rate reductions are partially offset by Access Recovery Charges (ARCs) on end users

  47 CFR Part 51 is the regulatory backbone of post-1996 local phone competition — the rules that required AT&T, BellSouth, Verizon, and other ILECs to open their networks to CLECs (companies like MCI WorldCom and Covad that entered the local market after the 1996 Act). While the CLEC competitive entry wave of the late 1990s largely faded after the dot-com bust and subsequent UNE-P (UNE Platform) rule changes, Part 51 remains operative for interconnection arrangements, especially for CLECs providing business voice services over ILEC copper loops and for the wireless-wireline interconnection rules governing the termination of calls between networks. The TELRIC pricing standard (§ 51.505) was upheld by the Supreme Court in Verizon Communications v. FCC (2002) and remains the FCC's forward-looking cost methodology for UNE pricing wherever it still applies. The 2011 bill-and-keep reform (FCC 11-161) substantially restructured Subpart H and set a 10-year glide path for eliminating per-minute intercarrier compensation charges — a reform that has significantly affected the economics of small rural phone companies that relied on access charge revenues.

• 47 CFR Part 54 — Universal Service (257 sections across 20 subparts — the FCC's complete regulatory framework for the $8+ billion/year Universal Service Fund):

  • Subpart C — Eligible Telecommunications Carriers (5 sections): only FCC-designated ETCs may receive USF support; state commissions designate ETCs for their states; wireless carriers can be ETCs; ETC obligations include advertising services and publicizing support amounts
  • Subpart D — High Cost Support (21 sections): the legacy high-cost program for carriers serving areas where the cost of providing telephone service exceeds the national average; carrier-specific support calculated using cost models; Connect America Fund (CAF) framework for larger carriers and rate-of-return support for smaller rural carriers; build-out obligations tied to high-cost support — carriers must offer voice and broadband to a minimum percentage of supported locations
  • Subpart E — Low-Income Consumers / Lifeline (20 sections): monthly subsidy for low-income consumers (qualifying at or below 135% of the federal poverty level or participating in specified assistance programs); the subsidy amount is set periodically by the FCC; Lifeline can be used for either voice or broadband service; one Lifeline benefit per household; supported by SNAP, Medicaid, veterans' pension, and tribal eligibility criteria; fraud and waste is a chronic program challenge — the FCC has required enhanced identity verification and increased carrier compliance auditing
  • Subpart F — Schools and Libraries (E-Rate) (15 sections): the E-Rate program subsidizes broadband internet and telecommunications services for K-12 schools and public libraries; annual funding is approximately $4 billion; school districts and library systems apply annually to USAC (Universal Service Administrative Company) for priority 1 services (telecommunications and broadband — fully funded at the 90% discount level for the most disadvantaged schools) and priority 2 services (Wi-Fi equipment and installation — funded when funds remain); eligible entities must be in USAC's program and comply with competitive bidding requirements for all funded services
  • Subpart G — Rural Health Care (34 sections — largest): broadband funding for rural health care providers; two programs — the Telecommunications Program (cost difference between rural and urban rates for voice/data services) and the Healthcare Connect Fund (HCF, consortium and individual healthcare provider broadband support up to 65% cost); telehealth infrastructure subsidized by this program expanded significantly during COVID-19; annual funding is approximately $700 million
  • Subpart H — Administration (14 sections): USAC (Universal Service Administrative Company) administers all four USF programs under FCC oversight; USAC is a private not-for-profit organization — a unique administrative structure; FCC reviews all USAC decisions; contributors to USF are all interstate and international telecommunications providers; contribution factor (the percentage of interstate revenues paid into USF) is set quarterly by FCC and has been trending upward as interstate revenues decline while program costs rise
  • Subpart L — Mobility Fund (22 sections): one-time and ongoing support for mobile broadband deployment in areas without 4G LTE service; Phase I provided one-time support; Phase II (5G Fund) is providing up to $9 billion over 10 years for 5G coverage in rural areas, including tribal lands priority
  • Subpart O — Uniendo a Puerto Rico Fund and Connect USVI Fund (24 sections): dedicated USF programs for rebuilding and expanding broadband infrastructure in Puerto Rico and the U.S. Virgin Islands following Hurricanes Maria and Irma (2017); separate from the mainland high-cost program; funded at approximately $950 million for Puerto Rico and $48 million for USVI over 10 years
  • Subpart Q — Emergency Connectivity Fund (19 sections): temporary COVID-era program ($7.17 billion) to fund off-campus broadband connections and devices for students, library patrons, and school staff who lacked internet access at home; expired after funding disbursement but demonstrated scale of federal broadband investment possible outside the permanent USF structure
  • Subpart R — Affordable Connectivity Program (15 sections): successor to the Emergency Broadband Benefit; $30/month ($75/month on qualifying tribal lands) broadband discount for low-income households; ran from 2021 until funding exhausted in April 2024; affected approximately 23 million households who lost the subsidy when ACP expired without congressional reauthorization

• 47 CFR Part 61 — Tariffs (55 sections — the FCC's rules governing how common carriers file, publish, and revise their tariffs with the Commission; implements the Communications Act's requirement that interstate carrier charges be publicly posted and non-discriminatory). Key provisions:

  • § 61.1 — Purpose and application: Part 61 applies to all FCC-regulated common carriers required to file tariffs, primarily interstate interexchange carriers and incumbent local exchange carriers (ILECs) for regulated services; international carriers with Title II obligations also fall within the Part's scope
  • § 61.13 — Electronic filing: all carriers required to file tariffs must do so electronically through the FCC's Electronic Tariff Filing System (ETFS); tariff publications must be filed in a format compatible with public retrieval via the FCC's tariff database
  • § 61.14 — Method of filing: publications filed electronically are captioned to the FCC Secretary; letters of transmittal must accompany all tariff filings specifying the nature of the changes, effective date, and legal justification for the filing
  • § 61.15 — Letters of transmittal: must be filed concurrently with tariff publications and must include a statement of the date of filing, the proposed effective date, and identification of changed pages; without a proper letter of transmittal, a tariff filing is procedurally deficient
  • § 61.16 — Base documents: carriers must maintain a complete "Base Document" incorporating all effective tariff revisions as of the preceding month's end; the Base Document is the authoritative consolidated version of the carrier's tariff and must be available for public inspection
  • § 61.17 — Special permission applications: a carrier may apply for FCC permission to file a tariff on less than the standard 15-day notice (§ 61.58) — used when market conditions require urgent rate changes or when a rate filing is needed to cure a compliance deficiency
  • § 61.131–61.136 — Concurrences for through services: when two carriers jointly provide end-to-end service and the originating carrier's tariff covers the through rate, the second carrier must file a "concurrence" — a formal agreement that the originating carrier's tariff governs the jointly-provided service; concurrences may be revoked by notice and are used to allocate interstate revenue among jointly-operating carriers
  • § 61.171–61.172 — Successor carrier obligations: when a carrier transfers its operating properties to a successor, the successor must adopt the original carrier's tariff by filing an Adoption Notice; rates and terms transfer with the carrier authority, preventing gaps in service during M&A transactions

  Common carrier tariff obligations under Part 61 are a legacy of the pre-deregulation telephone era when AT&T's Bell System was the dominant interstate carrier. Following the AT&T divestiture (1984) and the Telecommunications Act of 1996, tariff requirements were eliminated for most competitive interstate long-distance services ("detariffing") — most long-distance and wireless carriers now set rates through individual contracts without FCC tariff filing. However, ILECs providing interstate access services (the charges for connecting long-distance calls to local networks) remain subject to tariff requirements, and the tariff filing rules continue to govern access charge rates that all long-distance callers pay, embedded in their carrier's costs. The FCC's online tariff database (fcc.gov/telecommunications/tariffs) remains the authoritative source for interstate access rates.

• 47 CFR Part 63 — Extension of Lines, New Lines, and Discontinuance of Service by Common Carriers; International Section 214 Authorizations (39 sections — the FCC's procedural framework implementing Section 214 of the Communications Act of 1934, which requires common carriers to obtain FCC authority before constructing new lines, extending existing lines, acquiring operating rights, or — critically — discontinuing service):

  • § 63.01 — Domestic Section 214 blanket authority: any party that is or would be a domestic interstate common carrier is automatically authorized to provide domestic interstate services, build new facilities, or extend existing lines without seeking advance FCC approval; the FCC eliminated advance domestic approval requirements for new entry and expansion in the 1990s competition reforms — the regulatory bottleneck is now at the state PUC level, not the FCC, for domestic entry
  • § 63.03 — Domestic transfers of control: a carrier seeking FCC approval to transfer control of its Section 214 authorization (i.e., a merger or acquisition of a common carrier) files an application that receives streamlined 30-day review if the transaction is uncontested and the public interest showing is straightforward; contested transactions or those raising competition concerns receive full review (typically 180 days); large mergers (AT&T/T-Mobile, Sprint/T-Mobile) require DOJ antitrust review concurrently, and the FCC's public interest review can impose conditions that the DOJ review cannot
  • § 63.11 — Notification and prior approval for U.S. carriers affiliated with foreign carriers: a U.S.-authorized international carrier must notify the FCC and may need FCC approval before it becomes affiliated with a foreign carrier that has 25% or more ownership stake; if the foreign affiliate has market power in a particular country (controls essential facilities, lacks competitive alternatives), the FCC may impose conditions on the U.S. carrier's international traffic routing arrangements to prevent the affiliate from leveraging market power at the expense of U.S. customers
  • § 63.14 — Prohibition on special concessions: no international carrier authorized under Part 63 may agree to receive preferential facilities, routing arrangements, or access terms from a foreign carrier in exchange for routing international traffic — the "no special concessions" rule prevents foreign incumbents from striking side deals with U.S. carriers that circumvent competitive international settlement rates and effectively lock out other U.S. carriers from those routes
  • § 63.19 — Discontinuance of international service: unlike domestic service, discontinuance of international services requires advance FCC approval; a carrier must file an application to withdraw from an international route; the FCC must ensure continuity of service to affected customers and evaluate whether competing carriers can absorb the traffic before approving discontinuance
  • §§ 63.500–63.505 — Domestic service discontinuance applications: a carrier seeking to dismantle a trunk line, sever connections with another carrier, or discontinue local telephone service must file a detailed application showing: affected customers and their alternatives, notice given to customers, the timing of discontinuance, and the carrier's assurance that no customer will be left without a comparable alternative; these rules govern the copper network retirement process — AT&T, Verizon, Lumen, and other ILECs have been systematically discontinuing copper PSTN service in communities where they are deploying fiber or exiting the wireline business; a 2023 FCC order (88 FR 21444) strengthened customer notice requirements and required carriers to verify that alternative broadband-based service (VoIP) is available and functional before retiring copper-based POTS (plain old telephone service)

  Part 63 is the procedural gateway for carrier entry, M&A, and exit in the communications market. The most visible current application is copper retirement: major ILECs have disclosed plans to retire millions of copper POTS (plain old telephone service) lines and replace them with fiber-based voice service (VoIP) or simply exit the wireline market in some areas. Customers who rely on copper for medical monitoring devices, alarm systems, or fax machines — where VoIP service may be inadequate — face potential service disruptions. The FCC's 2023 rules require ILECs to give 180 days' advance notice to affected customers and to document that a comparable voice service is available and accessible before they can discontinue copper service. Consumer advocates have argued the protections are insufficient for vulnerable customers, while ILECs argue that maintaining copper networks indefinitely impedes investment in fiber. The proceeding continues to generate filings at the FCC as the copper retirement accelerates.

• 47 CFR Part 64 — Miscellaneous rules relating to common carriers (privacy, slamming, cramming, call completion)

• 47 CFR 64.2005-64.2010 — Customer Proprietary Network Information (CPNI) (restricts telecom carriers' use and disclosure of customer data without approval; requires safeguards, notice, and opt-in consent for sharing with third parties)

• 47 CFR Part 11 — Emergency Alert System (EAS): the FCC's rules governing the broadcast-based national emergency alert infrastructure that delivers emergency warnings through AM/FM radio, TV broadcast stations, cable systems, satellite radio (SiriusXM), and direct broadcast satellite. The EAS is the legacy emergency alerting system — mandatory for broadcasters, complementary to but distinct from the wireless WEA (Part 10) system. Key provisions:

  • § 11.2 — Definitions: the National Emergency Message (EAN) — formerly called the Emergency Action Notification or "Presidential alert" — is the highest-tier EAS activation that all EAS participants must transmit; the EAN is the broadcast equivalent of WEA's Presidential Alert; lower-tier messages include State and Local Area alerts from state and local officials and the National Weather Service
  • § 11.11 — EAS composition: the EAS encompasses AM, FM, and Low-power FM stations; digital audio broadcasting (DAB) stations; television broadcast stations; cable systems (all sizes); satellite digital audio radio services (SiriusXM); direct broadcast satellite services (DirecTV, DISH); digital television; and other distribution systems; cable operators must pass through EAS alerts from head-end to all subscribers; the EAS is the "backbone" network over which alerts cascade
  • § 11.18 — EAS Designations and the Primary Entry Point (PEP) system: the EAS operates through a tiered network architecture; at the top are approximately 77 Primary Entry Points (PEPs) — cooperatively selected AM and FM radio stations that serve as the first-transmit stations for a Presidential EAN; PEPs receive alert audio directly from FEMA's All-Hazard Emergency Message System (AHEM) and broadcast simultaneously to seed the cascade; below PEPs are Local Primary (LP), State Primary (SP), and National Primary (NP) stations with decreasing priority in the cascade; Participating National (PN) stations receive EAS from the network
  • § 11.21 — State EAS Plans: each state must develop and maintain an EAS plan specifying: which stations serve as State Primary sources; the relay network within the state; the header codes used for different types of state and local alerts; procedures for activating the EAS during different emergency scenarios; coordination with the National Weather Service; the state plan is reviewed by FEMA and the FCC's state coordinator
  • § 11.31 — EAS protocol (the four-part message structure): every EAS alert transmission consists of: (1) Preamble and EAS Header Codes (data blocks identifying the event code, affected areas (counties/states), duration, and originator); (2) Attention Signal (the distinctive two-tone alert tone that signals an incoming EAS message, not to be confused with the WEA alert tone); (3) Audio message (the actual emergency information — voice or synthesized); (4) Preamble and End Of Message (EOM) codes (signaling that the alert has concluded); EAS header codes use standardized SAME (Specific Area Message Encoding) format — a digital code preceding the audio that allows automated equipment to decode and filter messages; broadcast stations and cable systems must transmit the complete four-part message
  • §§ 11.35–11.61 — Equipment requirements (Subpart B): all EAS participants must have FCC-approved EAS equipment that can: receive EAS alerts from designated sources; decode SAME header codes; store received messages; automatically activate and interrupt regular programming to broadcast EAS alerts; generate appropriate audio signals; equipment must be tested and maintained at specified intervals
  • Subpart E — Tests: the EAS requires two types of tests: (1) Required Weekly Tests (RWT) — weekly audio tests between 8:30am and local sunset conducted on a rotating schedule; (2) Required Monthly Tests (RMT) — monthly full EAS activations including all four message parts; the FCC also conducts periodic National Periodic Tests (NPT) — nationwide EAS activations testing the full national cascade, typically announced in advance; the first nationwide EAS test was conducted in November 2011

  The EAS and WEA serve complementary functions: EAS is the broadcast backbone (reaches anyone with a TV or radio, including people without cell phones), while WEA is the cellular network (reaches smartphones directly with location targeting). FEMA's IPAWS (Integrated Public Alert and Warning System) is the federal platform that sends messages to both systems simultaneously. The EAS's primary limitation is geographic granularity — SAME codes can target specific counties but not sub-county geographies, while WEA can target specific polygon areas. Recent rulemakings: 87 FR 39698 (July 2022) — updated EAS equipment requirements for enhanced accessibility features (visual and tactile alerts); 86 FR 71718 (December 2021) — national EAS test procedures update.

• 47 CFR Part 10 — Wireless Emergency Alerts (WEA): the FCC's rules implementing the Warning, Alert, and Response Network (WARN) Act, governing the system that sends geographically targeted emergency messages to cell phones in affected areas without requiring subscribers to opt in. Key provisions:

  • § 10.2 — Voluntary participation: WEA is voluntary — CMS providers are not required to participate, but essentially all major carriers have elected to participate; non-participating carriers face subscriber notification requirements (§§ 10.240–10.250) that effectively publicize non-participation and create market pressure to join
  • § 10.10 — Four alert categories: (1) Presidential Alerts — government-originated national emergency messages; subscribers cannot opt out of Presidential Alerts at any level (carrier or device); the class was tested nationwide in October 2018; (2) Imminent Threat Alerts — severe weather, terrorism, life-threatening events; subscribers may opt out; (3) AMBER Alerts — child abduction emergencies; subscribers may opt out under § 10.280; (4) Public Safety Messages — non-life-threatening notifications; subscribers may opt out
  • § 10.280 — Subscriber opt-out rights: for AMBER and Imminent Threat classes, carriers that participate must allow subscribers to opt out; the opt-out operates at the device firmware level (phones can silence the WEA tone) rather than carrier filtering; Presidential Alerts cannot be blocked at any level
  • § 10.320 — Provider gateway requirements: participating CMS providers must maintain a secure, redundant, reliable gateway supporting the Common Alerting Protocol (CAP) format connected to FEMA's IPAWS; gateways must support geographic targeting (sending to devices in specified polygons, not entire service areas)

  WEA uses cell broadcast technology — a one-to-many broadcast to all compatible devices within range of specified cell towers, reaching roaming devices and devices with unknown numbers. The character limit for WEA messages has been extended from 90 to 360 characters on 4G/5G devices to allow actionable information. Recent rulemakings: 88 FR 86837 (December 2023) — updated participation election procedures; 84 FR 3507 (February 2019) — Spanish-language support and geographic targeting accuracy requirements.

• 47 CFR Part 80 — Stations in the Maritime Services (338 sections): the FCC's comprehensive radio licensing and technical standards framework for vessels operating in U.S. waters. Key provisions:

  • Subpart B — Applications and licenses: ship station licenses are required for vessels operating on U.S. navigable waters that use radio; license applications filed through the FCC's Universal Licensing System
  • Subpart C — Operating requirements and procedures (51 sections): radiotelephone testing procedures (§ 80.101); station identification (§ 80.102 — call sign plus vessel name in English at the beginning of each communication and at intervals); prohibited communications; priority of distress calls
  • Subpart D — Operator requirements: persons operating ship radio stations must hold an FCC-issued operator credential; GMDSS-equipped vessels require a GMDSS Radio Operator's License (§ 80.1073 — at least two GMDSS operators required)
  • Subpart G — Safety watch requirements: compulsory vessels must maintain continuous radio watches on distress frequencies (Channel 16 VHF-FM is the international hailing and distress frequency)
  • Subpart U — Bridge-to-bridge radiotelephone (§§ 80.1001–80.1023): implements the Vessel Bridge-to-Bridge Radiotelephone Act; applies to all power-driven vessels 20 meters or over and vessels 100 gross tons and up; must maintain a radiotelephone capable of operating on Channel 13 (156.650 MHz, navigational) and Channel 22A (157.100 MHz, Coast Guard liaison); use restricted to the master or designated navigator
  • Subpart W — Global Maritime Distress and Safety System (GMDSS) (36 sections): mandatory for all passenger ships and cargo ships of 300 gross tons and over (§ 80.1065); requires two GMDSS Radio Operator's Licenses onboard (§ 80.1073); equipment must be inspected annually by an FCC-licensed GMDSS Radio Maintainer (§ 80.1067); vessels must be capable of ship-to-shore distress alerting by two independent means on sea areas (A1: VHF coastal, A2: MF coastal, A3: satellite, A4: HF global) (§§ 80.1069, 80.1081); EPIRBs (emergency position-indicating radio beacons) and SARTs (search-and-rescue transponders) are core GMDSS equipment

• 47 CFR Part 15 — Radio Frequency Devices (106 sections — the FCC's foundational rule for consumer electronics; every device that emits radio frequency energy — computers, Wi-Fi routers, Bluetooth speakers, microwaves, LED drivers — is either authorized under Part 15 or must hold a separate FCC license). The three device categories and their authorization paths:

  • Incidental radiators (§ 15.13): devices that emit RF energy as a byproduct of operation (electric motors, fluorescent lighting, switching power supplies); must use good engineering practice to minimize emissions; no prior authorization required; subject to complaint-based enforcement if they cause interference
  • Unintentional radiators (§§ 15.101–15.123): digital devices and peripherals that generate RF signals but are not designed to radiate by antenna — computers, printers, monitors, cable boxes, TV receivers; divided into Class A (commercial/industrial) and Class B (residential use); Class B emission limits are stricter, reflecting the closer proximity to sensitive radio receivers in homes; authorization through either Declaration of Conformity (manufacturer self-certification with FCC-registered lab testing — most consumer electronics) or Certification (FCC review of test results — higher-risk devices); must carry the FCC ID or Part 15 compliance statement in instruction materials; TV broadcast receivers must display V-chip blocking technology (§ 15.120)
  • Intentional radiators (§§ 15.201–15.260): devices that deliberately transmit RF energy — Wi-Fi access points, Bluetooth devices, cordless phones, baby monitors, radar detectors, remote controls; all require FCC Certification before marketing; transmit only within permitted frequency bands and power limits; antennas cannot be modified to boost power beyond certified limits (§ 15.204); restricted bands (§ 15.205) near aviation navigation, GPS, and federal radar frequencies are off-limits for unlicensed intentional radiators regardless of power level
  • Key technical limits: Class B digital devices at 3 meters must not exceed 100 μV/m at frequencies from 30–88 MHz, rising to 500 μV/m at 960–1000 MHz (§ 15.109); intentional radiators in the 902–928 MHz and 2400–2483.5 MHz ISM bands (where Wi-Fi and Bluetooth operate) may use spread spectrum techniques allowing higher EIRP than the general 30 mW limit; outdoor Wi-Fi (5.8 GHz UNII-3 band) may use up to 1 W output with directional antennas up to 23 dBi gain
  • The Part 15 compliance statement: the FCC requires that instruction manuals for Class B unintentional radiators include the following statement (§ 15.105): "This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation." This statement appears on hundreds of millions of consumer electronics sold in the United States annually and is the most widely printed FCC regulatory text in existence
  • Enforcement: Part 15 is a general authorization, not a license — the FCC cannot revoke it from a specific device owner; enforcement targets manufacturers and importers through Notices of Apparent Liability; penalties can reach $25,000 per device type per day of violation; recall orders are available for devices causing widespread harmful interference to licensed services

• 47 CFR Part 5 — Experimental Radio Service (74 sections across 9 subparts): the FCC's licensing framework for radio transmissions conducted for research, development, testing, and market evaluation purposes — distinct from commercial licenses because experimental stations may use any frequency band and any emission type not available under commercial service rules, allowing innovators to test technologies that don't yet fit into the commercial licensing framework. Six types of experimental authorizations:

  • Conventional experimental radio licenses (Subpart B/C): for companies, universities, and research organizations conducting R&D, prototype testing, and proof-of-concept demonstrations; licenses issued for up to 2 years (renewable); applicants must describe the experimental program, requested frequencies, power levels, geographic area, and duration of operations; conventional licenses authorize communications only with other experimental stations or as specifically needed for the experiment (§ 5.111); stations must operate at the minimum power necessary and minimize interference to licensed services
  • Program experimental radio licenses (Subpart E): blanket authorizations for entities with recurring experimental needs — allows a company to conduct a defined scope of experiments without seeking individual approval for each test; program licensees must report annually on experiments conducted under the blanket authority; valuable for large R&D organizations (automotive, aerospace, technology companies) that continuously test multiple device configurations
  • Broadcast experimental licenses (Subpart D): for testing new broadcast equipment, systems, or technologies in the broadcast bands; may not be used for regular program service; broadcast experimental licensees often test new codec technologies, modulation schemes, or transmission systems before they're incorporated into broadcast service rules
  • Medical testing experimental licenses (Subpart F): narrow authorizations for testing medical devices that use RF energy (implantable devices, wireless monitoring equipment, imaging systems); tied specifically to the medical testing program described in the application; important pathway for FDA-regulated medical devices that must also meet FCC RF emission requirements before commercial deployment
  • Spectrum Horizons experimental licenses (Subpart I): created in 2019 for frequencies above 95 GHz where the Commission has not established traditional licensed or unlicensed services; license terms up to 10 years; designed to enable experimentation in millimeter wave and terahertz (THz) bands that may support 6G cellular, imaging, sensing, and other emerging technologies; the FCC established this pathway to prevent the regulatory framework from becoming a barrier to innovation at spectrum frontiers
  • Product development and market trials (Subpart H): allows device manufacturers to place experimental devices with up to 2,500 users in a limited geographic area for market testing before commercial FCC certification; devices may not be sold (no compensation may be exchanged) — they are placed with users for evaluation only; this pathway bridges the gap between R&D testing and commercial deployment, giving manufacturers real-world usage data to refine products before seeking commercial authorization

  Part 5 is the entry point for new wireless technologies into the U.S. market. Technologies including 5G millimeter wave beamforming, automotive radar, Wi-Fi 6E, and satellite direct-to-cell communications were tested under experimental licenses before the FCC established commercial service rules. The FCC's experimental licensing database (available at wireless.fcc.gov) is a public record of the wireless technologies companies are developing — patent filings and experimental license applications often appear simultaneously as early signals of emerging technology directions.

• 47 CFR Part 97 — Amateur Radio Service: the FCC's complete regulatory framework governing amateur ("ham") radio operations in the United States. With approximately 750,000 licensed amateur operators in the U.S., Part 97 is one of the FCC's most widely-applied service rules. Key provisions:

  • § 97.1 — Purpose: amateur radio exists for five regulatory purposes: advancing communications and technical skills, expanding the existing pool of trained radio operators for emergencies, providing voluntary non-commercial communications, promoting international goodwill, and contributing to communications experimentation and development
  • § 97.5 — Station license required: every amateur station must be under the control of a person holding a valid FCC amateur operator/station license; the license grant authorizes both the operator (the person) and the station (the equipment) — a unified license
  • §§ 97.501–97.527 (Subpart F) — Licensing and examination system: amateur operator licenses are issued in three classes — Technician (entry-level; VHF/UHF privileges plus limited HF), General (all-band HF privileges with some restrictions), and Amateur Extra (full operating privileges across all amateur bands); each class requires passing a written examination administered by FCC-accredited Volunteer Examiner teams; license term is 10 years (§ 97.25), renewable without re-examination; there is no FCC license fee for amateur radio (eliminated in 2022, now a small administrative fee via ARRL/VE teams)
  • § 97.113 — Prohibited transmissions: amateur stations may not transmit communications for hire or material compensation, music, obscene language, false distress signals, or encrypted messages intended to hide their meaning; the prohibition on compensation-based communications is what distinguishes amateur service from commercial broadcasting
  • § 97.115 — Third-party communications: an amateur station may transmit messages on behalf of a non-licensed person (a third party), but third-party traffic to foreign countries is only permitted where the foreign government has a formal reciprocal arrangement with the U.S. — a list maintained by the FCC
  • § 97.119 — Station identification: each amateur station must transmit its FCC-assigned call sign at the end of each communication and at least every 10 minutes during a communication; call signs are in standardized formats (e.g., K1ABC, W6XYZ, KD9ZZZ) assigned by the FCC ULS database
  • § 97.301 — Authorized frequency bands: amateur service has allocated spectrum across a wide range from 135.7 kHz (LF/MF) through the microwave bands; the most commonly used HF (shortwave) bands include 160m, 80m, 40m, 20m, 15m, and 10m; VHF/UHF includes the popular 2m (144-148 MHz) and 70cm (420-450 MHz) bands; band access depends on operator class (Technician vs. General vs. Extra)
  • § 97.313 — Transmitter power standards: amateur stations must use the minimum power necessary to carry out the desired communications; the maximum power level is 1.5 kW PEP (peak envelope power) output; specific bands or modes may have lower power limits
  • §§ 97.401–97.407 (Subpart E) — Emergency communications: amateur stations may use any available means to provide essential communications in an emergency, even overriding normal frequency and emissions restrictions; the Radio Amateur Civil Emergency Service (RACES) — registered with civil defense organizations — provides a formal structure for government-coordinated emergency amateur communications; amateur radio's role in disaster response (ARES/RACES teams) is recognized by FEMA and has been critical in hurricanes, earthquakes, and wildfires where commercial communications infrastructure fails

  Amateur radio is the only radio service where individuals are licensed to build their own transmitters and operate across a wide variety of frequency bands and modes. Part 97's self-governance ethos — enforced by community norms and the FCC's licensing system rather than routine inspections — makes it unusual among FCC services. The ARRL (American Radio Relay League) serves as the national membership organization and a key liaison to the FCC on rule changes. For the 33% of licensed amateurs who hold only Technician class licenses, upgrading to General (which requires passing the 35-question General exam) unlocks worldwide shortwave communications — one of the significant privileges that motivates exam preparation.

• 47 CFR Part 9 — 911 Service Requirements: FCC's comprehensive framework for 911, Enhanced 911 (E911), and Next Generation 911 (NG911) service — the rules that connect callers to emergency services and ensure location data is transmitted. Part 9 applies to telecommunications carriers, interconnected VoIP providers, wireless carriers, Multi-Line Telephone System (MLTS) operators, and mobile satellite service providers:

  • § 9.10 — 911 service mandate: all telecommunications carriers and covered interconnected VoIP providers must transmit 911 calls to a Public Safety Answering Point (PSAP); carriers may not block, delay, or otherwise interfere with 911 calls; an obligation to transmit all 911 calls exists even if the caller has no service agreement with the carrier (a cell phone with no service contract must still be able to call 911)
  • § 9.11 — E911 requirements: "Enhanced 911" means routing the call to the appropriate PSAP with automatic number identification (ANI) and automatic location identification (ALI) — the caller's phone number and location; for Phase I, carriers must provide the cell tower location; for Phase II, carriers must provide handset-derived location within specified accuracy requirements (horizontal accuracy of 50–150 meters depending on technology); the accuracy requirements reflect the public safety reality that dispatchers need precise location to send help
  • § 9.16 — MLTS/enterprise 911 requirements: operators of Multi-Line Telephone Systems (office buildings, hotels, campuses, hospitals — any facility with an internal phone system) must configure the system to (1) allow users to directly dial 911 without first dialing a trunk prefix ("9"); (2) automatically notify an on-site person (front desk, security) when a 911 call is made; and (3) provide dispatchable location information — not just "building X" but a specific location within the building (floor, wing, room) that a first responder can actually find; the "Kari's Law" and "RAY BAUM's Act" requirements (codified at §§ 9.16(a)–(b)) are named for real people who died because 911 systems in hotels and office buildings prevented or delayed emergency response
  • § 9.19 — Network reliability: covered 911 service providers (carriers, PSAPs, and related entities) must maintain reliable 911 service; outage reporting is required within 120 minutes for qualifying 911 service disruptions; FCC maintains a 911 Reliability section that tracks major outages; several significant nationwide 911 outages (including a 2020 T-Mobile network failure) have prompted FCC enforcement and technical guidelines
  • § 9.29 — NG911 transition: Next Generation 911 replaces legacy analog telephone switching with IP-based call routing; NG911 enables call centers to receive texts, photos, and video from the public (not just voice calls); the transition also enables interconnection between PSAPs for call overflow and geographic routing; FCC encourages NG911 adoption and requires carriers to comply with NG911 routing requests from 911 authorities once technically feasible
  • §§ 9.21–9.26 — 911 fee diversion prohibition: states and localities collect fees from telephone customers (usually a small per-line monthly charge) explicitly for funding 911 services; these sections implement FCC oversight of states that may "divert" 911 fees to general government funds rather than emergency communications; states that divert fees must disclose this annually, and FCC may restrict federal funding if diversion continues

• 47 CFR Part 14 — Access to Advanced Communications Services and Equipment by People with Disabilities: the FCC's implementing rule for Section 716 of the Communications Act (added by the Twenty-First Century Communications and Video Accessibility Act of 2010, CVAA), which requires that advanced communications services (ACS) and the equipment used to provide them be accessible to people with disabilities — or made compatible with assistive technology — if achievable:

  • § 14.1 — Coverage: applies to (1) manufacturers of equipment used for advanced communications services (smartphones, VoIP handsets, broadband routers, computers used for ACS), and (2) providers of advanced communications services (interconnected VoIP, non-interconnected VoIP, electronic messaging services, interoperable video conferencing services); "advanced communications services" is broadly interpreted to include IP-based voice, messaging, and video — covering most modern communications apps and devices
  • § 14.2 — "Achievable" standard: manufacturers and providers are not absolutely required to provide accessibility if doing so is not achievable — defined as feasible with reasonable effort or expense; the achievability analysis considers: (1) the nature and cost of the step needed to make the service or equipment accessible; (2) the technical and economic impact on the manufacturer's or provider's operations and products; (3) the type of operations; and (4) the extent to which the manufacturer or provider in question has resources; the achievability defense recognizes that some legacy systems or small providers may face genuine technical barriers
  • § 14.20 — Core obligations: covered entities must (1) ensure that equipment and services are accessible to people with disabilities (can be fully operable without relying on a specific sense or ability); (2) usable by people with disabilities (features are implemented in accessible ways); and (3) compatible with assistive technology (peripheral devices and software designed to assist people with disabilities can interface with the product)
  • § 14.21 — Performance objectives: accessibility means that individuals with disabilities can locate, identify, activate, configure, and use the equipment and service; specific objectives cover input/output, manipulation, voice input, audio output, visual output, and operable controls; if a feature cannot be made accessible, the equipment or service must be compatible with assistive technology that provides the function; the "compatible" alternative matters for screen readers, captioning decoders, and TTY/TDD devices
  • § 14.2 — Recordkeeping and complaint process: manufacturers and service providers must keep records of their accessibility efforts for two years after discontinuing a product or service; consumers may file ACS accessibility complaints with the FCC through the Consumer Complaint Center; the FCC may refer unresolved complaints to an Accessibility Dispute Resolution Process involving industry-retained accessibility advocates

  Part 14 extended the Americans with Disabilities Act and Section 508 (federal procurement) accessibility frameworks into the commercial communications products market. The CVAA and Part 14 have driven accessibility improvements in smartphones, video calling software, and messaging applications — the FCC regularly updates its enforcement priorities as technology evolves. For consumers with disabilities, Part 14 is the legal basis for requiring that communications equipment and services work with assistive technology, while Part 79 covers TV and online video.

• 47 CFR Part 79 — Accessibility of Video Programming: the FCC's comprehensive rules requiring that television programming, streaming video, and video-capable devices include closed captions, audio description, and accessible emergency information. Part 79 implements Sections 713 and 203 of the Communications Act (as amended by the CVAA):

  • § 79.1 — Closed captioning of televised video programming: broadcast and multichannel video programming distributors (MVPDs — cable, satellite, telco TV) must provide closed captions for virtually all programming; Spanish-language programming must also be captioned; caption quality standards require accuracy, synchrony, completeness, and placement (captions may not obscure on-screen faces or important information); the FCC enforces caption quality through complaints and periodic audits; every television must be sold with a functioning caption decoder capable of displaying CEA-708 digital captions
  • § 79.2 — Accessible emergency information: when a broadcaster delivers emergency information (tornado warnings, evacuations, shelter-in-place, AMBER alerts) as audio-only crawls, the same information must be provided in visual text; broadcasters that use audio descriptions of emergency graphics (a visual emergency notification on screen) must also make that audio accessible to the deaf/hard-of-hearing through a visual text equivalent; since 2018, some broadcasters must provide emergency information through a secondary audio stream that is audibly accessible to the blind
  • § 79.3 — Audio description: the top broadcast stations in the top 60 designated market areas (DMAs) must provide audio description (verbal narration of key visual elements during natural pauses in dialogue) for at least 50 hours per calendar quarter of prime-time and children's programming; audio description allows people who are blind or have low vision to follow the visual narrative of a program; the 50-hour quarterly minimum has been progressively increased since the CVAA; streaming video provided by the same entities that provide described programming on broadcast must provide equivalent audio description for that programming when distributed online
  • § 79.4 — Online video closed captioning: video programming distributed via Internet Protocol — streaming services, websites, and apps that distribute content previously shown on television — must be captioned if the underlying content was captioned when broadcast; this requirement means that Netflix, Hulu, Amazon Prime Video, and similar services must caption all their licensed television and film content that aired on U.S. television; clips, trailers, and behind-the-scenes content have separate rules; the rule has been progressively tightened to cover more categories of online video content
  • §§ 79.102–79.109 — Equipment requirements: all television sets, set-top boxes, DVRs, Blu-ray players, and video streaming devices must include functioning caption decoders; user interfaces for navigating programming and changing accessibility settings must be accessible; devices must allow one-touch activation of accessibility features (closed captions, audio description) without navigating multiple menus; navigation devices (remote controls, on-screen guides) must allow users with disabilities to browse programming listings and activate accessibility features independently

  Part 79 is one of the most user-visible federal accessibility mandates — the "CC" button on every remote control and the caption track options on every streaming service exist because of these rules. Enforcement is complaint-driven: consumers can file Part 79 complaints at the FCC Consumer Complaint Center (consumercomplaints.fcc.gov) for specific failures of captioning quality or availability. The FCC has fined broadcasters millions of dollars for systematic captioning failures. Recent rulemakings: 87 FR 67139 (November 2022) — updated online captioning rules to require auto-generated captions to meet accuracy standards; 83 FR 29862 (June 2018) — expanded audio description requirements to top 60 DMAs.

• 47 CFR Part 90 — Private Land Mobile Radio Services (232 sections across 21 subparts): the FCC's comprehensive licensing and technical standards framework for private radio systems that are not open to the general public — including public safety communications (police, fire, EMS), business and industrial radio, transportation communications, and specialized mobile services. Part 90 is one of the largest and most operationally significant parts of the FCC's wireless rules because it governs the radio systems that coordinate emergency response, industrial operations, and critical infrastructure across the country. The six major categories of service:

  • Public Safety Radio Pool (Subpart B): frequencies reserved exclusively for government and qualifying public safety agencies — state and local police departments, fire departments, emergency medical services, public works, and highway maintenance. Licensees must be governmental entities or entities authorized to provide public safety communications; the public safety pool includes VHF (150-174 MHz), UHF (450-512 MHz), and 800 MHz bands historically assigned to public safety; the FCC protects these frequencies from commercial encroachment and requires that public safety systems have technical priority over co-channel business users
  • Industrial/Business Radio Pool (Subpart C): business and industrial users — manufacturers, utilities, pipeline operators, oil companies, construction firms — may license private radio systems for internal business communications; these systems support plant coordination, fleet dispatch, and field operations; business licensees must demonstrate they are engaged in regular business activity that justifies private radio (as opposed to using commercial CMRS networks); the industrial pool includes VHF and UHF frequencies shared with public safety under frequency coordination rules
  • 800 MHz Specialized Mobile Radio (Subpart S, §§ 90.1001–90.1055): the 806-824 MHz and 851-869 MHz bands, originally allocated to private land mobile (SMR) in the 1970s, which became the basis for commercial mobile data and dispatch networks (Nextel's iDEN network was built in 800 MHz SMR spectrum); the 800 MHz band rebanding — a decade-long, $950 million spectrum reconfiguration completed around 2013 — separated public safety from commercial SMR operations to eliminate mutual interference; public safety agencies now operate in the 806-815 MHz band and commercial SMR in the 817-824 MHz band, with guard bands between them
  • 220 MHz Service (Subpart T, §§ 90.1001–90.1019): the 220-222 MHz band, auctioned competitively under § 90.1001, supports narrowband services including telemetry, data, and paging; licensees may partition and disaggregate geographic area licenses under § 90.1019 to sell portions of spectrum or geography to secondary licensees
  • Intelligent Transportation Systems (Subpart M, §§ 90.371–90.389): the 5.850-5.925 GHz band allocated for vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) communications supporting collision avoidance, traffic management, and autonomous vehicle applications; ITS Radio Service licensees are state and local transportation agencies; the FCC's 2020 ITS reallocation decision divided the 5.9 GHz band between automotive safety (lower 30 MHz) and unlicensed Wi-Fi (upper 45 MHz), a significant shift that prioritized broadband connectivity over vehicle safety communications
  • 4.9 GHz Public Safety Broadband (Subpart Y, §§ 90.1201–90.1217): the 4940-4990 MHz band exclusively for public safety agencies, providing high-capacity broadband for video surveillance, interoperable communications, and emergency operations; only government entities providing public safety services (§ 90.1203) may hold 4.9 GHz licenses; licensed systems may share the band with temporary fixed stations and mobile units; the 4.9 GHz band has been underutilized relative to its capacity, prompting FCC proceedings on how to maximize its use for public safety broadband

  Operating requirements (Subpart N) apply across all Part 90 services: frequency coordination requirements (§ 90.175) — applicants for new stations must coordinate proposed operations with existing licensees through FCC-designated frequency coordinators; interference protection — stations must be engineered to not cause harmful interference to co-channel licensees within the coordination distance; identification — all stations must identify by transmitting their FCC call sign; control point requirement — each station must have an accessible control point from which operations can be suspended immediately. Technical standards (Subpart I) set emission limits, antenna height restrictions, and equipment authorization requirements: all transmitters used in Part 90 services must be certified under Part 2 of the FCC's rules, and the Part 90 bandwidth and power limits (§§ 90.205–90.215) determine what modulation rates and frequencies are permissible.

  Part 90 licenses are issued on a site-by-site basis (for fixed systems) or a geographic area basis (for certain mobile and SMR services). The Universal Licensing System (ULS) is the FCC's electronic database and filing system for all Part 90 licenses — frequency coordinators, applicants, and licensees interact with ULS to file applications, renew licenses, and search for existing licensees when performing frequency coordination. License terms are 10 years; renewal requires demonstration of continued eligibility and operation. Recent rulemaking: the FCC's ongoing 6 GHz proceeding (adjacent to the 4.9 GHz public safety band) and the post-Nextel 800 MHz rebanding completion are the most significant recent developments affecting Part 90 licensees.

• 47 CFR Part 52 — Numbering: the FCC's rules governing the North American Numbering Plan (NANP) and telephone number assignment within the United States — the framework that determines how phone numbers (area codes, central office codes, and subscriber numbers) are assigned, administered, and protected from anti-competitive hoarding. Part 52 implements the Communications Act's requirement that the FCC oversee number portability and numbering administration:

  • §§ 52.11–52.16 — North American Numbering Plan Administration: the FCC designates a North American Numbering Plan Administrator (NANPA) — a non-governmental, independent entity responsible for administering the NANP across the U.S., Canada, and participating Caribbean nations; the current NANPA is SOMOS, Inc.; key NANPA functions: assigning Numbering Plan Areas (NPAs — area codes) when existing codes approach exhaustion; assigning Central Office (CO) codes (the 3-digit NXX that follows the area code) to telecommunications providers; maintaining the publicly accessible NANP database; administering the Billing and Collection (B&C) Agent function that charges providers for number administration
  • § 52.15 — Central office code administration: each NANPA-assigned CO code provides 10,000 phone numbers (0000–9999); providers request CO codes when they need number blocks to serve customers; the North American Numbering Council (NANC — an FCC advisory committee composed of carrier representatives, state regulators, and consumer advocates) advises the FCC on numbering policy, including when new area codes are needed and what number conservation measures are required
  • §§ 52.101–52.111 — Toll-free number administration: toll-free numbers (800, 833, 844, 855, 866, 877, 888 area codes) are administered by a separate Toll Free Numbering Administrator (TFNA) — currently SOMOS; providers acquire toll-free numbers for their customers through "Responsible Organizations" (RespOrgs), which are registered entities that can reserve and manage toll-free numbers in the TFNA database; the rules address three toll-free number market dysfunctions: warehousing (§ 52.105 — a RespOrg reserving numbers with no customer), hoarding (§ 52.107 — a subscriber acquiring more numbers than it intends to use), and excessive brokering (charging fees for number transfers); § 52.109 imposes a permanent cap of 2,000 reserved numbers or 7.5% of the RespOrg's active inventory on number reservations
  • § 52.109 — Permanent reservation cap: a Responsible Organization may not hold more than 2,000 toll-free numbers in "reserve" status (not yet assigned to a subscriber) or 7.5% of its active inventory, whichever is greater; this prevents carriers and brokers from hoarding vanity toll-free numbers (e.g., 1-800-FLOWERS-style numbers) to sell at a premium, which the FCC has found constitutes unjust enrichment at the expense of businesses that need toll-free numbers for customer service

  The telephone numbering framework directly affects phone number availability and competition. When an area code is exhausted (too many numbers assigned to carriers), NANPA and the relevant state public utility commission implement relief — typically a new overlay area code (adding a new area code to the same geographic area, requiring 10-digit dialing) rather than a split (dividing the geographic area and reassigning one portion to a new code). The NANP database also underpins Local Number Portability (LNP) — the system that lets consumers keep their phone numbers when switching carriers, which is administered separately under FCC rules implementing 47 U.S.C. § 251(b)(2).

• 47 CFR Part 78 — Cable Television Relay Service (CARS) (44 sections across 4 subparts — the FCC's licensing and technical standards framework for cable television relay stations):

  CARS stations are microwave relay stations used by cable television operators to transport TV signals from the point of reception (a broadcast tower or satellite downlink site) to a cable system headend or distribution point. Before fiber optics became practical in the 1980s and 1990s, CARS microwave hops were the primary method for cable operators to pick up distant broadcast signals and retransmit them via cable. Authorized frequency bands include 2,025–2,110 MHz, 6,425–6,525 MHz, 6,875–7,125 MHz, 12,700–13,250 MHz, and higher microwave bands up to 19.7 GHz (§ 78.101). Each band has different maximum power limits and EIRP caps.

  Applications and licenses (Subpart B): CARS licenses are issued for specific point-to-point paths rather than geographic areas — an applicant files for a specific transmitting site to a specific receiving site. Frequency coordination with other CARS stations and with other microwave services (fixed, private, government) is required before the FCC grants the license. Operating requirements (Subpart C) include station identification, operator supervision, and log-keeping. Technical standards (Subpart D) govern emission masks, authorized bandwidth, and interference protection. While CARS usage has declined as fiber has replaced microwave relay for most cable distribution, active CARS licenses remain in use for rural cable systems and as backup paths. The statutory authority is the broad FCC communications licensing power at 47 U.S.C. § 152, rather than a specific cable-TV provision.

• 47 CFR Part 65 — Interstate Rate of Return Prescription, Procedures, and Methodologies (24 sections — the FCC's procedural framework for prescribing an authorized rate of return for telephone exchange carriers):

  Part 65 implements the FCC's authority to set a maximum allowed rate of return on interstate exchange access service — the regulatory mechanism that prevents incumbent local telephone companies from earning monopoly profits on their interstate telephone services. The rule is triggered by a market signal: § 65.101 provides that whenever the monthly average yield on 10-year U.S. Treasury securities remains at least one percentage point above or below the current authorized rate of return for six consecutive months, the FCC may initiate a prescription proceeding. The cost of capital methodology (Subpart C) specifies how to calculate cost of debt (§ 65.302), cost of preferred stock (§ 65.303), and capital structure weights (§ 65.304), then combine them into a weighted average cost of capital (§ 65.305) — the floor for the authorized rate of return.

  The maximum allowed rate of return is the computed cost of capital plus a 40-basis-point increment (§ 65.700). Exchange carriers whose actual interstate earnings exceed this ceiling must reduce rates. Those falling more than 100 basis points below the authorized rate must notify the FCC. The rate of return framework applies to regulated incumbent local exchange carriers (ILECs) — primarily the large Bell Operating Companies and remaining independent telcos. As competition has grown and most voice service has shifted to wireless and VoIP, the practical significance of rate-of-return regulation has diminished for large ILECs, but it remains the primary tool for regulating the roughly 1,000 smaller rate-of-return carriers serving rural areas under a separate Universal Service Connect America Fund regime.

• 47 CFR Part 32 — Uniform System of Accounts for Telecommunications Companies (190 sections — the FCC's mandatory accounting framework for incumbent local exchange carriers; authority: 47 U.S.C. § 219):

  The Uniform System of Accounts (USOA) is the financial backbone of telephone rate regulation. Before the FCC can prescribe an authorized rate of return under Part 65 or conduct cost-of-service proceedings for access charge disputes, it needs a consistent, standardized accounting record of what ILECs actually spend and earn. Part 32 provides that record by requiring ILECs to maintain their books in a prescribed chart-of-accounts format that separates regulated telecommunications activities from non-regulated and affiliate activities. Without the USOA's discipline, carriers could shift regulated costs to non-regulated subsidiaries, inflate the regulated cost base to support higher rates, or obscure cross-subsidization between competitive and captive services.

  Part 32 applies to incumbent local exchange carriers (ILECs) under § 251(h) of the Communications Act — principally the Bell Operating Companies and independent local telephone companies. Price cap carriers (large ILECs that have migrated to price cap regulation) and carriers offering business data services under § 61.50 may opt out of the full USOA requirements, since price cap regulation does not require the same cost-of-service underpinning as rate-of-return regulation. The roughly 1,000 smaller rate-of-return carriers serving rural areas remain fully subject to Part 32:

  • § 32.11 — Carriers subject to Part 32: ILECs and carriers the FCC designates by order; price cap opt-out option; non-dominant successor companies of ILECs are excluded; carriers must notify the FCC before switching regulatory regimes
  • § 32.101 — Balance sheet structure: the USOA divides balance sheet accounts into four zones: (1) current assets and other non-fixed assets (Account 1120 — Cash, through Account 1500 — Other jurisdictional assets); (2) regulated fixed assets, the Telecommunications Plant accounts (Account 2001 — Telecom plant in service, through Account 2007 — Goodwill, including plant under construction, held for future use, and under capital lease); (3) asset reserves (Accumulated depreciation Accounts 3100–3300, Accumulated amortization Accounts 3400); and (4) liabilities and stockholders' equity (Accounts 4000 — Current accounts/notes payable through Account 4550 — Retained earnings)
  • § 32.102 — Nonregulated investments: non-telecommunications activities conducted through the same legal entity as regulated operations but without joint use of assets must be tracked in the Nonregulated Investments account — this is the Part 32 firewall that prevents non-regulated ventures from distorting the regulated cost base
  • Subpart D (Revenue Accounts, §§ 32.5000–32.5280): USOA revenue accounts track four categories — local network service revenues, network access revenues (the access charges paid by interexchange carriers to connect to the local loop), long-distance revenues, and miscellaneous revenues from directory advertising, billing services, and other ancillary sources; the revenue account structure corresponds directly to the access charge proceeding categories that drive most ILEC rate proceedings
  • Subpart E (Expense Accounts, §§ 32.6110–32.7400): expense accounts are organized by the FCC's separations framework — plant-specific operations (expenses tied to specific categories of telephone plant), plant non-specific operations (expenses common to the entire network), customer operations (sales and marketing, operator services), corporate operations (executive, accounting, legal, human resources), and depreciation and amortization; the separation of plant-specific from plant non-specific expenses is critical because interstate vs. intrastate separations (how costs are divided between federal and state jurisdiction under 47 CFR Part 36) depend on this account structure

  The USOA's most important regulatory function is enabling the FCC's Part 64 Accounting Safeguards — the rules that prevent ILECs from subsidizing competitive services with regulated monopoly revenues. When a Bell Operating Company provides both regulated local exchange service and competitive long-distance or data services, Part 32's account separation rules create the audit trail for detecting affiliate transactions that shift monopoly profits to competitive affiliates or cross-subsidize competitive prices at the expense of regulated customers. State public utility commissions conduct intrastate rate proceedings using the same account structure, creating a consistent regulatory accounting framework from federal to state jurisdiction.

  Recent rulemakings: 82 FR 20842 (2017) — updated depreciation accounting provisions for telecom plant assets reflecting changes in technology lifetimes; 67 FR 5686 (2002) — significant revision simplifying the USOA for smaller carriers and aligning account categories with contemporary telecommunications services.

• 47 CFR Part 53 — Special Provisions Concerning Bell Operating Companies (8 sections — the FCC's implementing rules for Section 272 of the Telecommunications Act of 1996):

  Section 272 of the Telecom Act required Bell Operating Companies (BOCs — AT&T's regional successors: Verizon, AT&T regional units, CenturyLink/Lumen, and their predecessors) to provide certain interLATA (long-distance) services through a structurally separate affiliate before the BOC's own local exchange network had been opened to competition. The idea was to prevent a BOC from leveraging its local monopoly to gain an unfair advantage in the competitive long-distance market. Part 53 specifies exactly what structural separation means in practice:

  • § 53.203 — Operational independence: the Section 272 affiliate and the BOC may not jointly own transmission or switching facilities; must maintain separate books, records, and accounts; the affiliate must obtain access to BOC facilities at the same rates and on the same terms as any unaffiliated carrier (no preferential treatment); employees of the affiliate may not be officers, directors, or employees of the BOC simultaneously
  • § 53.209 — Biennial audit: a Federal/State joint audit must be conducted every two years by an independent auditor to verify that the BOC and its affiliate are actually operating independently, not sharing facilities or giving preferential access; audit scope includes financial records, operational systems access, and physical facilities
  • § 53.207 — Successor entities: if a BOC transfers network elements (required to be provided on an unbundled basis under § 251(c)(3)) to an affiliated entity, that affiliate inherits the structural separation obligations

  Most Section 272 BOC separation requirements sunset after three years from RBOC authorization to provide in-region long-distance service; Part 53 governs the residual requirements and audit obligations that survive the sunset for certain activities.

• 47 CFR Part 6 — Access to Telecommunications Service, Telecommunications Equipment, and Customer Premises Equipment by Persons with Disabilities (8 sections — the FCC's implementing rule for Section 255 of the Communications Act):

  Section 255 of the Telecom Act (47 U.S.C. § 255) requires manufacturers of telecommunications equipment and customer premises equipment (CPE) and providers of telecommunications services to make their products and services accessible to people with disabilities — if doing so is readily achievable. Part 6 translates this statutory command into compliance requirements.

  • § 6.5 — General obligations: manufacturers must design and develop equipment so that it is accessible to and usable by individuals with disabilities, if readily achievable; where it is not readily achievable to make the product accessible, manufacturers must ensure compatibility with peripheral devices and specialized customer premises equipment commonly used by people with disabilities
  • § 6.7 — Product design evaluation: manufacturers and service providers must evaluate accessibility during the design and development phase — not just at the end — and must consult with individuals with disabilities in that process
  • § 6.9 — Information pass-through: equipment must pass through cross-manufacturer, non-proprietary, industry-standard codes, translation protocols, formats, and industry standards to allow interoperability with assistive technology (screen readers, TTY devices, hearing aid compatibility systems)
  • § 6.11 — Documentation and training: companies must provide accessible information to their customers about product accessibility features; customer service representatives must be trained to handle accessibility inquiries
  • §§ 6.15–6.16 — Complaint procedures: any person may file an informal or formal complaint alleging violation of Section 255 or Part 6; the FCC's Consumer and Governmental Affairs Bureau handles informal complaints; formal complaints follow the Part 1 complaint adjudication procedures with potential civil penalties

  Part 6 covers traditional telecommunications equipment and services — landline phones, wireless phones (basic voice services), operator services, voicemail, call forwarding. The companion rule, 47 CFR Part 14 (added by the CVAA in 2010), extends similar requirements to advanced communications services including VoIP, text messaging, and video calling. Together, Parts 6 and 14 provide end-to-end accessibility coverage across both legacy and modern communications technologies.

Recent Developments

• The BEAD (Broadband Equity, Access, and Deployment) program from the Infrastructure Investment and Jobs Act ($42.5B) is the largest broadband infrastructure investment in U.S. history — state allocations were finalized in 2024 with deployment underway
• Net neutrality regulatory authority remains contested following the Supreme Court's Chevron deference reversal and Sixth Circuit's 2025 decision on FCC authority
• The Affordable Connectivity Program expired in 2024 after Congress did not reauthorize funding, ending $30/month broadband subsidies for ~23 million households
• E-Rate Wi-Fi hotspot rules withdrawn; Lifeline reform proposed (2025-2026): FCC partially withdrew its July 2024 E-Rate Wi-Fi hotspot lending rules — which would have allowed schools and libraries to lend subsidized Wi-Fi hotspots to students for home use — citing legal uncertainty about whether hotspot lending falls within E-Rate's statutory scope. The FCC separately proposed Lifeline reform (April 2026) to strengthen anti-fraud measures in the $9.25/month low-income broadband subsidy program, following Inspector General findings that a substantial percentage of Lifeline subscribers were ineligible or duplicatively enrolled. These changes tighten access to the two federal programs most directly supporting low-income household connectivity.
• 5G spectrum, AI robocalls, and net neutrality (2025-2026): Mid-band 5G spectrum deployment accelerated with CBRS band openings and C-band deployments by AT&T, Verizon, and T-Mobile. AI-generated robocalls — used for political messaging and scams — prompted FCC enforcement actions and rulemaking requiring voice carriers to implement more aggressive STIR/SHAKEN call authentication. Net neutrality remains unresolved: the Sixth Circuit's 2025 decision found the FCC lacked authority to impose broadband reclassification under the Chevron-free Loper Bright standard, leaving the 2024 net neutrality rule in legal limbo. The Republican-majority FCC under Chair Brendan Carr has indicated no intent to re-propose neutrality rules.
• In February 2026, the FCC sought comment on proposed application limits and eligibility restrictions for new noncommercial educational (NCE) reserved-band FM translator station applications in the upcoming 2026 filing window.
• In February 2026, the FCC announced an open meeting to consider a Notice of Proposed Rulemaking on reforms to the Lifeline program — the federal subsidy for low-income telecommunications access — seeking to ensure federal dollars reach eligible beneficiaries and reduce waste and fraud.
• National security threats in domestic telecom (April 2026): The FCC circulated a proposal to strengthen protections against national security threats in domestic telecommunications service, building on prior actions to remove equipment from designated companies (Huawei, ZTE) and expanding oversight of foreign-owned telecom providers.
• Electronic device testing integrity (April 2026): The FCC proposed new rules to ensure integrity and security in electronic device testing — addressing concerns that devices certified for U.S. markets may not meet actual emissions and safety standards if testing processes are compromised.
• FCC suspends seven convicted criminals from USF programs (April 2026): The FCC suspended seven individuals convicted of crimes from participating in Universal Service Fund programs, reinforcing anti-fraud enforcement in the $8+ billion annual USF subsidy system.
