New identity and governance assessment process will support expanded call authentication capabilities via interoperability between Governance Authorities worldwide.
WASHINGTON, D.C. AND MCLEAN, VA / ACCESS Newswire / July 23, 2026 / The Secure Telephone Identity Governance Authority (STI-GA), under the auspices of ATIS, today announced that it has selected Numeracle™, Inc. (Numeracle) to design and implement a comprehensive governance vetting framework for evaluating Non-Jurisdictional Governance Authorities (NJGAs) seeking interoperability with the U.S. STIR/SHAKEN ecosystem, the primary tool for the authentication of telephone caller identity.
Mandated domestically by the TRACED Act of 2019, STIR/SHAKEN has since become the foundation for global call authentication efforts. As STIR/SHAKEN deployment expands globally, governance authorities worldwide are working to establish trusted authentication environments capable of supporting existing national frameworks. To ensure the security of cross-border connections, the STI-GA is establishing a consistent approach to validate the identity, governance practices, and operational integrity of authorities requesting interoperability with the U.S. ecosystem.
The growing global momentum behind authenticated communication channels highlights the need for reliable mechanisms to confirm that each participating governance authority maintains sufficient controls to uphold the integrity of interconnected authentication frameworks. These developments emphasize the importance of consistent, rigorous vetting and ongoing oversight as global interworking evolves.
Under this engagement, the STI-GA and Numeracle have developed a comprehensive assessment process to evaluate an NJGA’s identity, governance structure, certificate-management security, and alignment with STI-GA policies, as well as its readiness for secure cross-border authentication. The framework also establishes procedures for ongoing monitoring to ensure continued compliance, enforcement consistency, and sustained trustworthiness over time.
“As authenticated communications adoption accelerates internationally, establishing trust between governance authorities is essential for global interoperability,” said Susan Miller, President and CEO of ATIS. “ATIS’ STI-GA is where the industry comes together to agree on the solutions that are advancing call authentication globally.”
Glenn Clepper, STI-GA Chair, stated “Our focus here is specifically on non-jurisdictional governance entities, those not established by national regulators, where independent validation is needed to ensure their policies and operations meet the security expectations required for technical interworking.”
“Authenticated communications only work if trust holds at every point in the chain. Fraud doesn’t stop at a border, so trust can’t either,” said Rebekah Johnson, Founder and CEO of Numeracle. “This framework gives governance authorities worldwide a consistent standard for vetting and accountability. The whole industry is required to work together to protect verified identity across networks and borders, and Numeracle is honored to help lead that effort.”
This collaboration supports the STI-GA’s mission to preserve the security and integrity of the U.S. STIR/SHAKEN ecosystem while laying the groundwork for trusted, cross-border interoperability as global governance models continue to emerge.
