What is STIR/SHAKEN?
STIR/SHAKEN is a set of technical standards and protocols that allow for the authentication and verification of caller ID information for calls carried over Internet Protocol (IP) networks that can assist communication service providers in preventing unwanted robocalls from connecting with their desired endpoints.
It allows service providers to place a digital signature on calls as they originate on their network, which verifies the call is being placed from someone with the right to use the number.

How does STIR/SHAKEN work?
STIR/SHAKEN digitally validates the handoff of phone calls passing through the complex web of networks. It allows phone companies to verify that a consumer's incoming call is in fact from the number displayed on Caller ID.
-
Why should I care about STIR/SHAKEN?
STIR/SHAKEN is a set of protocols and procedures mandated by the FCC to combat the rise in unwanted robocalls and unlawful caller ID spoofing. When adopted, carriers can present a trust indicator to recipients’ phones.
STIR/SHAKEN helps improve calling experiences by mitigating spoofed robocalls and, as a result, building consumers’ trust so they’re comfortable answering incoming calls.

Who needs to implement STIR/SHAKEN?
All U.S. voice providers and foreign providers delivering calls to the U.S. for termination must submit a certification of their implementation of STIR/SHAKEN or a robocall mitigation plan.
All voice telephony providers will have a new duty not to accept calls directly from service providers that have not submitted such certifications.
