STIR/SHAKEN registration that puts a “Caller Verified” badge on your calls
STIR/SHAKEN is a framework carriers use to verify the organizations and phone numbers behind mass calling.
Once carriers attest your numbers, contacts see a “Caller Verified” badge instead of “Potential Spam”, so your calls earn more trust and more answers.

Verified calls vs unverified calls
Carriers introduced STIR/SHAKEN to reduce fraudulent robocalls. When they attest your numbers, they can label your calls “Caller Verified” instead of “Potential Spam”.
Unverified and verified calls
| Unverified calls | STIR/SHAKEN verified calls |
|---|---|
| Carriers may label your calls “Potential Spam”. | Carriers can show a “Caller Verified” badge. |

| You can’t tell whether carriers see you as legitimate. | Carriers validate your organization and your numbers. |
