A2P Registration Rules for Canadian 10DLC Numbers in Sparkforge

By Sparkforge Support Team ·Last reviewed May 3, 2026

A2P registration is required for any Canadian 10DLC number sending SMS to U.S. recipients. Canada-only messaging may need A2P or Persona verification depending on when the number was purchased.

If you send SMS from a Canadian 10DLC long code number in Sparkforge, the registration rules depend on two things: where you are sending and when the number was purchased. Toll-free numbers are not affected by these rules.

Rule summary

Route	Number purchased before March 26, 2025	Number purchased on or after March 26, 2025
Canada to United States (CA to US)	A2P required	A2P required
Canada to Canada (CA to CA)	No registration required	A2P or Persona verification required

Messaging from Canada to the United States

A2P Brand & Campaign registration is required for every Canadian 10DLC number that sends SMS to U.S. recipients, whether the number is new or existing. Persona verification is not accepted for CA-to-US traffic. Complete A2P and wait for approval before sending.

Messaging within Canada

Numbers purchased before March 26, 2025

No registration is required for Canada-only messaging. If you later start messaging U.S. recipients, A2P registration becomes required.

Numbers purchased on or after March 26, 2025

You have two options for Canada-only messaging: complete A2P registration, or complete Persona verification if you do not want to do A2P.

What to do

Identify your messaging route (CA to US, CA to CA, or both).
Check the purchase date of the Canadian 10DLC number in your sub-account's phone management area.
If you message any U.S. recipients, complete A2P registration in the Trust Center.
If you only message Canadian recipients with a number purchased on or after March 26, 2025, complete A2P or Persona verification.
Wait for approval before sending.

If messages are failing

Confirm three things: the destination route, whether the number requires A2P or Persona based on its purchase date, and your registration status in the Trust Center. A pending or rejected registration will block delivery.

Frequently Asked Questions

Do these rules apply to toll-free numbers?

No. The rules cover Canadian 10DLC long code numbers only. Toll-free numbers follow a separate registration process.

Can I use Persona verification for CA-to-US messaging?

No. A2P Brand & Campaign registration is required for any Canadian 10DLC number sending SMS to U.S. recipients.

What if I started with Canada-only messaging and later want to send to the U.S.?

You must complete A2P registration before sending any CA-to-US messages, even if your number was previously exempt.

How do I find out when my number was purchased?

Check the purchase or assignment date in your sub-account's phone number management area. If you cannot find it, contact support with the number and sub-account details.

What happens if I send before registration is approved?

Messages will fail or be filtered. Wait for A2P or Persona approval to confirm before sending production traffic.
