For Canadian 10-digit long code (10DLC) numbers, there are a few things you need to keep in mind when messaging. Let’s take a look at what to do and how to do it.

Messaging Within Canada #

If your phone number was purchased before 26th March 2025, you’re not required to undergo Application-to-Person (A2P) registration for messaging fellow Canadians. If purchased after that point, A2P registration is mandatory to send messages to Canadian recipients.

Messaging to the United States #

To reach U.S. recipients, your 10DLC number must be A2P registered. This requirement applies to all Canadian numbers.

Messaging Content #

Ensure your messages contain a clear way for customers to disengage with your marketing, and avoid prohibited content categories to ensure compliance with legal regulations.

Follow these guidelines and enjoy your CRM’s messaging capability.
