Secure Telephone Identity Governance Authority

What Secure Telephone Identity Governance Authority does

The Secure Telephone Identity Governance Authority (STI-GA) is the FCC-designated governance body responsible for the STIR/SHAKEN (Signature-based Handling of Asserted information using toKENs) caller ID authentication framework in the United States. It operates under the umbrella of ATIS (Alliance for Telecommunications Industry Solutions), a non-profit standards organization, and is overseen by a Board of Directors drawn from the major US voice service providers and ecosystem participants, including AT&T, Verizon, Google, Comcast, Microsoft, and Charter Communications. STI-GA's core function is to define and enforce the policy framework governing how Service Providers obtain STI certificates, how call attestations are validated, and how governance disputes are resolved across the originating and terminating networks.

The authority manages STI Certification Authorities (STI-CAs), vets and approves participants, maintains the published STI Governance Authority documents, and coordinates cross-border interoperability with the Canadian Secure Token Governance Authority (ST-GA) under a 2022 Memorandum of Understanding. Its revenue model is non-commercial: STI-GA is funded through STI Participant fees and ATIS membership dues rather than product sales or transaction pricing. The organization periodically publishes new ATIS standards and policy enhancements, including extensions to toll-free numbers, TDM networks, and enterprise SIP call authentication, in response to evolving FCC mandates such as the Eighth Report and Order.

Because STI-GA is a regulatory governance function rather than a product vendor, its strategic relevance is measured by the scope of its framework and the breadth of its participant base rather than by commercial revenue. Key counterparties include voice service providers, equipment vendors, certificate authorities, and enterprise participants seeking attestation services; AI/ML capabilities are not part of STI-GA's mandate, with analytics-driven robocall mitigation handled by carriers and third-party vendors complementary to the STIR/SHAKEN cryptographic framework.

Core offering

STI-GA governs the STIR/SHAKEN caller authentication framework for the U.S. telecommunications industry, defining policies for certificate management, overseeing the STI-PA registration system (operated by iconectiv) for service providers, certification authorities, and Resp Orgs, and publishing authoritative technical standards (ATIS-1000074, ATIS-1000080, ATIS-1000082) and annual SHAKEN reports that track industry robocall mitigation progress. The organization enables voice service providers to authenticate caller ID through digital signatures to combat illegal robocalling and caller ID spoofing.

Product overview

STI-GA is a governance body, not a product company. It does not sell commercial products. Its offerings consist of governance documents, standards specifications, and operational guidelines that define how the STIR/SHAKEN caller authentication framework operates. The STI-GA Policy Decisions Binder establishes rules for certificate management; ATIS standards (ATIS-1000074, ATIS-1000080, ATIS-1000082, etc.) define the SHAKEN protocol specifications; and annual SHAKEN Reports track industry adoption metrics. The STI-PA Registration Portal (operated by iconectiv) is the primary service interface for ecosystem participants.
