What does a Verified Phone Call mean?

A verified phone call means the person who is calling us is authorized and verified by our phone carrier. The system of verification is used to reduce and avoid spam calls. These calls are verified by considering the attestation levels on the pre-decided scale. The “Stir and Shaken” standards are the technology that helps to authenticate the identity of the callers. The Secure Telephony Identity Revisited is the abbreviation of Stir and the Secure Handling of Asserted Information Using Tokens is the abbreviation of Shaken. This technology applies to both phone carriers and caller carriers to reduce spoofed calls. This service is not provided by every phone service, so this service may not be visible on all phones.

Attestation Scale 

There are three different attestation levels of attestation scale and all three levels are mentioned below:

Full Attestation

This is the highest attestation level which means the caller’s phone number is authorized and verified by our phone carrier or it is not a spoofed call. It displays the check mark on the phone number that indicates the number is verified by our phone carrier. 

Partial Attestation

This is the second attestation level in which the service provider knows who called us. However, the service provider doesn’t know whether the caller number is authorized or not. It does not display the check mark on the caller’s phone number. 

Gateway Attestation

It is the lowest attestation level of the attestation scale in which the phone carrier doesn’t know the caller’s identity and these calls are assigned from the international gateway. This attestation mostly indicates the spam number.
