STIR/SHAKEN Compliance for Calling Campaigns

Would you want your calls to be labeled “Potential Spam”? Of course not!

That’s why you must register for a STIR/SHAKEN attestation. Carriers implemented these protocols to verify and attest organizations and the phone numbers they use for mass calling.

STIR/SHAKEN comparison

STIR/SHAKEN is a new technology framework introduced to reduce fraudulent robocalls.

When adopted, carriers validate and attest your numbers. The attestation helps carriers determine if a call should be labeled as ‘Caller Verified’ or ‘Potential Spam’.

For a legitimate organization, your contacts will see the ‘Caller Verified’ badge when you call them. Fraudsters that illegally spoof caller IDs are identified and blocked.

How does STIR/SHAKEN help you?

The authenticated calls with the Caller Verified badge help you build trust among your contacts and increase your answer rate.

How does STIR/SHAKEN work?

You register for a STIR/SHAKEN attestation on CallHub [Settings > Compliance > SHAKEN/STIR] with details about your organization (including identifiers like your EIN number] and contact details. CallHub will submit this information to the carriers and get your number attested.

STIR/SHAKEN attestation levels

A-level attestation: Verifies caller identity and legitimate use of provided phone numbers for outgoing calls.

B-level attestation: Verifies caller identity but indicates uncertainty about their authorization to use specified phone numbers for calls.

C-level attestation, or Gateway Attestation: Applies when originating carriers can’t verify calls at A or B levels; often used for international calls.

Campaign teams ❤️ using CallHub


“When other platforms were struggling, CallHub could easily scale up quickly when needed; from texting 5 people to calling 5 million, we could trust CallHub.”

-John Robinson, Bernie Campaign
Organizing for Change
“A lot of our folks are volunteers, a lot of them are retired, they are often anxious with technology and they were able to use CallHub easily. It’s empowering for volunteers who don’t see themselves as very tech-savvy to be able to pick up a new piece of software and a new program and just use it, so that was great.”
-Celine Trojand, Organizer, Organizing for Change 
“I really love your team. You are just super responsive and super friendly and nothing’s too difficult! It’s been a really good experience.”
– Shaun Murray, Senior Organizer, GetUp
“We can make calls at about 5x the rate that we would with a manual dialer, getting through a list of 100 calls in just over an hour. This has been a huge capacity saver in our organization.”
– Amanda Destefano, Leadership Organizer, United Workers
