Understanding A2P 10DLC

A2P (Application-to-Person) 10DLC (10-Digit Long Code) is a system that allows businesses to send SMS and MMS messages using a standard 10-digit phone number through Aloware. While A2P 10DLC registration is a mandatory requirement in the United States by both the FCC and mobile carriers, the rules differ for Canadian traffic.

Knowing when registration is necessary for Canadian numbers is crucial to maintaining compliance.


Traffic scenarios and requirements

Here’s a quick guide to the different traffic scenarios and their corresponding A2P 10DLC registration requirements:

Type of traffic

Visual indicators in Aloware

When sending messages to US numbers without A2P 10DLC registration, a warning banner appears across Aloware's messaging interfaces. The banner serves as a reminder to complete registration before sending US-bound messages to ensure proper delivery.

This warning displays:

  • While selecting a line to send messages in Talk

  • Setting a line for broadcast

  • Selecting a line in sequences


Next steps for registration

To get started with A2P 10DLC registration, review your current messaging setup and assess your needs based on the scenarios outlined above. Make sure to complete any necessary registrations for US-bound messaging to ensure compliance and maintain message delivery rates.
