STIR (Secure Telephone Identity Revisited) / SHAKEN (Signature-based Handling of Asserted information using toKENs) is a framework designed to assign a certificate of authenticity to each phone call for use across the telecom network. These certificates act as a digital signature of trust passed from carrier to carrier to improve traceable call delivery.
STIR/SHAKEN is a requirement of the TRACED Act, and the FCC has also mandated that both originating and terminating voice service providers were to implement the STIR/SHAKEN caller ID authentication framework by June 30, 2021.
The execution of STIR/SHAKEN deployment requires that the relationship between the identity of the caller and the authorized use of its phone numbers be verified in order to pass STIR/SHAKEN authentication and achieve the "Verified Caller" display. If a service provider hasn't filed its certified Robocall Mitigation Plan with the FCC, its call may be blocked based on the upcoming September deadline.
