Understanding A2P Registration

What Is The A2P 10DLC Registration?

A2P (Application-to-Person) 10DLC is a messaging system required by U.S. carriers that allows businesses to send SMS and MMS messages to customers using a Local or Mobile number.

The goal of A2P registration is to verify your business and protect consumers from spam messages. Once registered, your messages are delivered more reliably, faster, and with fewer chances of being filtered or blocked.


🧾 Why A2P Registration Matters

Without A2P registration:

  • Your messages may fail to send.
  • You may experience delivery delays or filtering by carriers.
  • U.S. carriers may impose fines or block unregistered traffic.

With the registration:

âś… Higher message delivery rates

âś… Better compliance with carrier requirements

✅ Protects your phone number’s reputation
