Understanding A2P 10DLC

  • Updated

In this article, you will learn about A2P 10DLC.

What is A2P 10DLC?

A2P 10DLC is a new, standardized system in the US that allows businesses to send Application-to-Person (A2P) messages to consumers using a standard 10-digit long code (10DLC) phone number.

In 2022, major carriers across the US (e.g., T-Mobile, AT&T, Verizon) adopted A2P 10DLC, which impacts the way businesses can send messages to consumers. These changes apply to companies using a software service for business messaging such as Workiz Phone. These changes are beyond Workiz’s control and are ultimately designed to protect consumers from receiving potentially unwanted, spam-like messages.

How does A2P 10DLC work?

With these new changes, carriers are differentiating between P2P and A2P.

  • P2P: Basic text message exchanges between two people using mobile phones and SIM cards is known as Person-to-Person (P2P) messages.
  • A2P: Text message exchanges between a software application (such as Workiz Phone) and mobile phones is known as Application-to-Person (A2P) messages.

With A2P 10DLC, carriers are focusing on the second of these two messaging types: A2P.

A2P and P2P are also differentiated between purpose and send volume. Where P2P messages are often used for personal reasons, A2P messages are typically used for commercial purposes. This includes SMS marketing campaigns and appointment reminder messages.

A2P 10DLC supports transactional and promotional messaging for all US area codes.

The limitations to A2P 10DLC will vary depending on the mobile carrier your recipients use, including constraints on the number of message parts that can be sent per minute (AT&T) or the number of total messages that can be sent per day (T-Mobile).
