Mobile carriers implemented a new registration requirement to help verify messaging traffic from business phone numbers. These requirements apply to all customers sending SMS from long code numbers, regardless of country and use case.
-
Why is this happening?
As business SMS traffic increases, so do scammers sending fraudulent messages. Per the 10 Digital Long Code (10DLC) application to person (A2P) classification, legitimate businesses who register can send messages, and carriers can block spam texts from unregistered sources.
-
What do I need to do?
To ensure you are able to continue sending messages, you’ll need to register your business through RingCentral with The Campaign Registry (TCR), a third-party organization. This process verifies you’re a legitimate SMS/MMS messages source. To register, we require you to use the registration form we’ve provided on our website.

Which carriers require SMS compliance?
As of January 6, 2022, the following carriers require TCR registration:
-

-
What if I fail to register?
Everyone are required to register by March 31, 2023. Failure to register will result in SMS being disabled for your account, or any non-registered numbers. To make registration easier, RingCentral will allow self-registration through the admin portal starting February 10, 2023. In the interim, customers may register using the registration form we have provided on our website. -
How does CTIA relate to the FCC?
