What is 10DLC registration?
Updated over a week ago

In an effort to combat spam, and improve the delivery of legitimate text messages, the phone industry is requiring organizations that send text messages to US ten-digit phone numbers to register for A2P 10DLC.

What does A2P 10DLC stand for?

A2P stands for “Application to person” type messaging. In this case, NationBuilder is the application, and you can use your nation to send a text to a person.

10DLC stands for 10-digit long code, which is a technical name for a 10-digit phone number. Example: “555-555-5555”

What is 10DLC registration and why do we have to comply with it?

A2P 10DLC registration is a protocol that is part of a system in the United States that requires businesses to be verified to send texts to people through an app like NationBuilder.

An information hub known as The Campaign Registry (TCR) is the entity that sets out the requirements. The Campaign Registry has a mission to “provide a simplified, fair, and unbiased service by working with carriers, messaging companies, and industry partners to establish common standards for A2P 10DLC messaging.” They work in close collaboration with cellular phone providers in the United States and Canada.

How do I know if my organization needs to register for 10DLC?

If your organization sends text messages through NationBuilder to recipients in the United States from a 10-digit phone number ie: 555-555-5555, then it's recommended you register for 10DLC, and required for large volume senders.

If you do not send text messages to users in the United States, you do not need to do anything.
