What are the STIR/SHAKEN Attestation Levels and What Do They Mean?
November 30, 2022 / 0 comments

STIR/SHAKEN Attestation levels were developed by the Robocall Taskforce, established by the Federal Communications Commission in response to the overwhelming problem of illegal robocalls. Essentially, the attestation levels are designed to protect the integrity of the telecom networks and provide a way to signal confidence levels to other carriers that the calls can be trusted, and at what level.

 

What are the SHAKEN Attestation Levels?

STIR SHAKEN attestation levels were developed as part of the STIR/SHAKEN telecom protocol which was implemented in phases over the last two years. STIR/SHAKEN was developed in response to the increasing problem of robocalls and caller ID spoofing. To combat this issue, SHAKEN attestation verifies the degree to which the originating telecom carrier knows their customer (KYC) and if the telecom carrier knows the customer has authorization to use the Caller ID number they are inserting into the meta data of the call.
This attestation provides a simple way for carriers to communicate with each other about the potential legitimacy of the phone call.

There are three SHAKEN attestation levels, A, B, and C

A-Attestation (Full attestation) indicates that the telecom carrier that originated the call knows the customer that initiated the call and the customer is authorized to use the Caller ID that the call is being originated from.
B-Attestation (Partial attestation) indicates that the telecom carrier that originated the call knows the customer that initiated the call but does not have an LOA indicating that the customer is authorized to use the Caller ID that the call is being originated from.
C-Attestation (Gateway attestation) means that the telecom carrier does not know the caller’s identity and the source of the call cannot be identified. 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.
Telecom carriers must use the appropriate level of SHAKEN attestation when signing calls. If they do not, they could lose their telecom licenses. As such, telecom carriers have developed procedures to ensure that calls are properly signed with the appropriate level of SHAKEN attestation.

 

What does an attestation rating of C mean for a call?

An attestation rating of C means that the telecom carrier does not know the caller’s identity. This is the lowest level of attestation. Some carriers have a policy to block all calls that are transmitted with a C attestation.

 

What does an attestation rating of B mean for a call?

An attestation rating of B means that the telecom carrier knows the caller’s identity (KYC), but does not have an LOA on file documenting that the caller has authorization to use the Caller ID number.

 

Why is STIR/SHAKEN so important?

STIR SHAKEN attestation levels are a set of technologies that aim to combat robocalling. The goal is to make it more difficult for scammers to disguise their identities, making it easier for regulators and law enforcement to find and penalize the illegal robocallers.
This is important because caller ID spoofing is a common tactic used by scammers to trick people into thinking they are being called by a legitimate business or person. By making it more difficult for scammers to spoof caller ID, STIR/SHAKEN makes it easier for consumers to know who is really calling them.
STIR/SHAKEN is also important because it is a step towards creating a trustworthy marketing and communications channel. As we become increasingly reliant on our phones for communication, it is important that we have confidence that the calls are not scammers or other illegal robocallers trying to trick us and exploit us.
