Increase deliverability with SHAKEN/STIR
SHAKEN/STIR aims to ensure that the caller ID information your contacts see on their phone matches the actual origin of the call. It works by verifying the authenticity of the caller's information and attaching a digital signature to the call, so that the receiving phone network can verify if the call is legitimate or not. It was developed to allow mobile carriers like Verizon, T-Mobile, and AT&T, etc. to prevent unwanted spam calls from being delivered to mobile users.
What is SHAKEN/STIR?
SHAKEN is an acronym for "Secure Handling of Asserted information using Tokens":
STIR is also an acronym for "Secured Telephony Identity Revisited"
How does it work?
When a call passes through a network that supports SHAKEN/STIR, it's validated against the digital signature, and if it's verified as legitimate, the caller ID information remains unchanged. If the call doesn't match or fails the verification, it might be labeled as "unverified" or "potential spam" on your phone's display.
What do I need to do?
To ensure your calls get through and your tracking number isn't flagged as "spam," we urge you to register your phone number with SHAKEN/STIR.
How do I register?
As part of the A2P 10DLC requirement, SHAKEN/STIR validation is included in both the Low-Volume Brand and High-Volume Brand tiers. If you are currently registered under the Sole Proprietor Brand tier and wish to add SHAKEN/STIR validation, upgrade your registration to either the Low-Volume Brand or High-Volume Brand tier.
