What you need to do

Use the checklist below based on your messaging route:

If you message U.S. recipients (CA → US)

1. Complete A2P Brand & Campaign registration for your Canadian 10DLC number.
   
   

2. Only begin messaging U.S. recipients after your registration is approved.

Additional details

• These requirements are based on destination country (where the recipient is) and the purchase date of the Canadian 10DLC number.
  
  

• If your business messaging needs change (e.g., you start messaging U.S. recipients), you may need to complete A2P even if you previously sent only within Canada.

FAQs

Q: Do these requirements apply to toll-free numbers?

No. These requirements apply to Canadian 10DLC long code numbers. Toll-free numbers are not affected.

• Purchased on or after March 26, 2025: you can send Canada-only messages by completing A2P registration or Persona verification (if you choose not to complete A2P).

Confirm:

• The destination route (CA → CA vs. CA → US)
