Put Numbers Attestation For Free

Attestation is a crucial part of the STIR/SHAKEN process and includes three categories to determine essential information about the caller by evaluating the ?attestation? level of each call. These attestation levels distinguish a caller's validity to use a specific number.

Gateway Attestation (C) ? The service provider has authenticated from where it received the call, but cannot authenticate the call source. An example of this case would be a call received from an international gateway.

Full Attestation (A) - The identity of the caller is known, and they have the right to use the Caller ID for this call. Partial Attestation (B) - The originator knows the identity of the caller, but cannot confirm their right to use the Caller ID.

"Gateway Attestation", "C", indicates the call can only be verified as coming from a known gateway, for instance, a connection to another service provider.

If a call is assigned full attestation, it means: The carrier is responsible for originating the call. The carrier has a pre-existing direct relationship with the customer who is making the call and can authenticate and identify this caller. The carrier can verify an association with the number used to make the call.

Before completing a call to the intended party, one of three levels of Attestation is assigned: Full Attestation, Partial Attestation, and Gateway Attestation. Full Attestation (A) means the service provider authenticated the caller and phone number.

There are three SHAKEN attestation levels, A, B, and C This simply means that the call has been routed through a gateway that is STIR-SHAKEN compliant. Calls with this level of attestation are most likely to be blocked or tagged as spam.
