What is U.S. A2P 10DLC?

A2P 10DLC is the system in the U.S. that enables the sending of Application-to-Person (A2P) messages through a 10-digit long code (10DLC) phone numbers. 10DLC is the new, approved solution in the U.S. for A2P messaging over long numbers.

By switching to A2P 10DLC, businesses can now engage with their consumers through a verified local identity. This new system will increase deliverability and throughput. U.S. Carriers, AT&T and T-Mobile are requiring a registration process so that they know who they are and what messages they are sending.

What do you need to do?

If you do not send messages via local long codes within the United States, you do not need to do anything.

This will prevent disruptions to your messaging service and ensure that you keep sending engaging and time-critical messages to your customers.

Why the change to A2P 10DLC?

Carriers want end-users to have a better customer experience and receive relevant text messages that are not spam. The more regulated ecosystem to send SMS traffic over U.S long numbers will prevent misuse and have added benefits for your company and customers. Failure to adhere to the new rules and regulations will result in SMS traffic being blocked and possible fines implemented.
