STIR/SHAKEN: authenticating the use of a caller number

Updated 2026-10-30 · Prepared by Call Global Communications Inc

Short answer: STIR/SHAKEN provides a framework for providers to sign and verify assertions about calling-number authorization. It addresses a part of caller identity in supported IP telephone networks.

A verified assertion does not certify the truthfulness of a conversation or display a business name. It is distinct from CNAM and does not make an unwanted call acceptable.
