Carrier Registration for STI Policy Administrator and Certification Authority Services

To participate in the Secure Telephone Identity (STI) call authentication ecosystem, Canadian carriers must be members of the CST-GA, LLC consortium.

Becoming an authorized carrier in the call authentication ecosystem in Canada is a tightly controlled process to ensure the integrity of the framework and is the only way to originate or receive verified calls within the SHAKEN framework.

Once registered, approved carriers can request and receive a Service Provider Code Token, that allows them use the Token to obtain an STI Certificates from the Certification Authority and use them to then start authenticating calling party information by referencing this issued STI Certificate.
