§2518 Procedure for interception of wire, oral, or electronic communications

Title 18 › Part PART I— - CRIMES › Chapter CHAPTER 119— - WIRE AND ELECTRONIC COMMUNICATIONS INTERCEPTION AND INTERCEPTION OF ORAL COMMUNICATIONS › § 2518

Last updated Apr 6, 2026|Official source

Summary

You must make a written, sworn request to a judge to get permission to listen to or record someone’s wire, oral, or electronic communications. The request must say who is asking and include required facts and details. A judge can ask for more testimony or papers. The judge can approve the request without telling the target, if the facts support it. Any order must spell out key details like who/what is to be intercepted, where and how it will happen, time limits, and steps to avoid listening to people who are not the target. Any order can last no longer than 30 days. The 30-day period starts on the earlier of the day interception first begins or 10 days after the order is entered. The order can be extended, but only by applying again and meeting the same judge-made findings, and any extension can be no longer than 30 days. Orders must be carried out as soon as possible, must try to minimize non-target interceptions, and must stop when the goal is met or after 30 days. If a message is in a code or foreign language and no expert is available, minimization can happen as soon as practical after interception. Government staff or contractors can do the interception under supervision. The judge may require progress reports. Before any trial or hearing, each party must get a copy of the order and application at least 10 days beforehand, unless the judge allows a shorter time. A service provider asked to help can ask the court quickly to change or cancel an order if help cannot be given in time.

(1)Each application for an order authorizing or approving the interception of a wire, oral, or electronic communication under this chapter shall be made in writing upon oath or affirmation to a judge of competent jurisdiction and shall state the applicant’s authority to make such application. Each application shall include the following information:
(2)The judge may require the applicant to furnish additional testimony or documentary evidence in support of the application.
(3)Upon such application the judge may enter an ex parte order, as requested or as modified, authorizing or approving interception of wire, oral, or electronic communications within the territorial jurisdiction of the court in which the judge is sitting (and outside that jurisdiction but within the United States in the case of a mobile interception device authorized by a Federal court within such jurisdiction), if the judge determines on the basis of the facts submitted by the applicant that—
(4)Each order authorizing or approving the interception of any wire, oral, or electronic communication under this chapter shall specify—
(5)No order entered under this section may authorize or approve the interception of any wire, oral, or electronic communication for any period longer than is necessary to achieve the objective of the authorization, nor in any event longer than thirty days. Such thirty-day period begins on the earlier of the day on which the investigative or law enforcement officer first begins to conduct an interception under the order or ten days after the order is entered. Extensions of an order may be granted, but only upon application for an extension made in accordance with subsection (1) of this section and the court making the findings required by subsection (3) of this section. The period of extension shall be no longer than the authorizing judge deems necessary to achieve the purposes for which it was granted and in no event for longer than thirty days. Every order and extension thereof shall contain a provision that the authorization to intercept shall be executed as soon as practicable, shall be conducted in such a way as to minimize the interception of communications not otherwise subject to interception under this chapter, and must terminate upon attainment of the authorized objective, or in any event in thirty days. In the event the intercepted communication is in a code or foreign language, and an expert in that foreign language or code is not reasonably available during the interception period, minimization may be accomplished as soon as practicable after such interception. An interception under this chapter may be conducted in whole or in part by Government personnel, or by an individual operating under a contract with the Government, acting under the supervision of an investigative or law enforcement officer authorized to conduct the interception.
(6)Whenever an order authorizing interception is entered pursuant to this chapter, the order may require reports to be made to the judge who issued the order showing what progress has been made toward achievement of the authorized objective and the need for continued interception. Such reports shall be made at such intervals as the judge may require.
(7)Notwithstanding any other provision of this chapter, any investigative or law enforcement officer, specially designated by the Attorney General, the Deputy Attorney General, the Associate Attorney General, or by the principal prosecuting attorney of any State or subdivision thereof acting pursuant to a statute of that State, who reasonably determines that—
(8)
(9)The contents of any wire, oral, or electronic communication intercepted pursuant to this chapter or evidence derived therefrom shall not be received in evidence or otherwise disclosed in any trial, hearing, or other proceeding in a Federal or State court unless each party, not less than ten days before the trial, hearing, or proceeding, has been furnished with a copy of the court order, and accompanying application, under which the interception was authorized or approved. This ten-day period may be waived by the judge if he finds that it was not possible to furnish the party with the above information ten days before the trial, hearing, or proceeding and that the party will not be prejudiced by the delay in receiving such information.
(10)
(11)The requirements of subsections (1)(b)(ii) and (3)(d) of this section relating to the specification of the facilities from which, or the place where, the communication is to be intercepted do not apply if—
(12)An interception of a communication under an order with respect to which the requirements of subsections (1)(b)(ii) and (3)(d) of this section do not apply by reason of subsection (11)(a) shall not begin until the place where the communication is to be intercepted is ascertained by the person implementing the interception order. A provider of wire or electronic communications service that has received an order as provided for in subsection (11)(b) may move the court to modify or quash the order on the ground that its assistance with respect to the interception cannot be performed in a timely or reasonable fashion. The court, upon notice to the government, shall decide such a motion expeditiously.
