Voice Service Providers have been directed by the FCC to implement robust call authentication by the end of 2019. STIR/SHAKEN standards create a secure framework to guarantee caller ID is accurate.


Secure Telephony Identity Revisited (STIR) is a set of technical standards developed by the Internet Engineering Task Force (IETF) to certify the identity of originating calls.


Signature-based Handling of Asserted information using toKENs (SHAKEN) is a framework developed by the Alliance of Telecommunications Industry Solutions (ATIS) to implement STIR within IP-based service provider networks.

Neustar is a co-author of STIR, co-contributor to SHAKEN and exclusive host of the ATIS Robocalling Testbed for validating STIR / SHAKEN implementations.

Digital certificates are used to authenticate phone calls, similar to the way web transactions are validated. With STIR/SHAKEN in place, spoofed calls can be detected and stopped before they reach consumers, or a warning displayed on caller ID.

How STIR/SHAKEN will block spoofed calls:

  1. When a spoofer places a call, the originating carrier cannot verify that the entity is authorized to use that number, so no authentication token is attached.
  2. Without a token, the call fails verification at the terminating carrier.
  3. A warning is displayed on caller ID, or the call is blocked.

Adoption of STIR/SHAKEN

Many carriers are in progress of implementing this call authentication technology.

In a survey taken early 2019, here's what respondents shared where they are in implementing call authentication.
