Canada SMS Features and Restrictions


Canada has very specific messaging restrictions and a direct connection is necessary to ensure message delivery to the numerous networks. Vonage uses an extremely high-quality, direct connection to deliver your SMS to Canada.

Sender ID

All SMS sent to Canada must originate from either a US or Canadian pre-approved long number that is associated with your Vonage API account. Alpha sender IDs are not supported.

Limited numeric sender only. In the “from” field you need to specify your pre-approved Canadian (or US) virtual number in international format, for example, 18479121345. Otherwise your message will get rejected with the API response code 15 Illegal Sender Address - rejected.

You can purchase pre-approved long virtual numbers from the Numbers tab in your Vonage API account dashboard.


P2P: Person-to-Person traffic may be sent to Canada from a long virtual number using the SMS API. SMS may originate from a mobile phone, a computer application, or an internet-based service, but the message must have been initiated due to human interaction.

A2P: Application-to-Person (A2P) traffic may be sent to Canada using the Alerts Short Code API.

Restricted Content

All CAN Numbers traffic adheres to the CWTA guidelines. For more information, see the CWTA Handbook Guidelines.
