AT&T Call Trace (*57)

Find out who called with Call Trace.


Learn about Call Trace

Note: Call Trace helps you handle obscene, harassing or threatening calls. This feature should only be used to trace harassing or threatening calls that warrant legal action. After activating Call Trace, you must contact your local law enforcement agency. Successful trace information is provided only to the customer's law enforcement agency and will be used when investigating harassment. Information obtained is never divulged to the customer by AT&T.

Call Trace allows you to initiate an automatic trace of the last incoming call received. You must dial the designated code to activate the option each time you want to trace the last call. You don't need to keep the caller on the line for any length of time for Call Trace to work. Call Trace is a pay-per-use option in which charges will be reflected on the bill following usage. When dialing *57, customers agree to accept charges for using the service.

To activate Call Trace, follow these steps:
  1. After receiving a harassing call, hang up the phone.
  2. Immediately pick up the phone and press *57 to activate call trace. Choices are *57 (touch tone) or 1157 (rotary).
    • If Call Trace is successful, a confirmation tone and message will be heard. A written log tracking date and time of annoyance calls must be kept by the customer in order to retrieve Call Trace information.
    • An error message will let you know if the call can't be traced.
    • In case of an emergency, contact your local law enforcement agency.

Note: Hearing impaired customers should dial *57 to activate call trace and keep a written log of the time and date of the harassing call or calls. This information is critical in tracing the call.

After call trace activation
  • Contact your local law enforcement agency.
  • Information is released only if law enforcement authorities follow proper legal process to request records.
  • The time, date, and phone number involved are recorded at an AT&T location and saved approximately for one year.

Helpful hints

  • Call Trace traces the last number that called you. Therefore, *57 must be dialed immediately after the harassing call and prior to receiving another call or hearing the call waiting tone.
  • You are not charged for unsuccessful attempts. However, you are billed for successful attempts, even if there is no follow up action on the captured number. Charges vary by area of service.
  • This option is not available in all areas.
