10DLC (10 Digit Long Code) registration refers to the process of registering a standard 10 digit phone number for a business to use for sending SMS and MMS messages to customers. Technically, this is only currently necessary when sending to the United States, but is now required by most messaging providers in Canada as well. It is not possible to limit messages to just Canada, and message may pass through US providers even when going between Canadian numbers. The registration process ensures that the 10DLC number is approved, and the messaging services meet carrier guidelines and industry regulations. Once registered, messages stand a better chance of delivery and not being caught in anti-spam filters.

Brand and campaign registration

As part of the registration process, you will need to provide information about your business or organization, including the company name, address, company website,  company registration number and DUNS number. You will also need to describe the purpose or campaign for which you will use the 10DLC number (e.g., low volume business communication, marketing, customer support, or notifications).

The application also needs to describe how users can opt in to your program.  For example,  a customer could text “START” to your number, or register on a website.

It should also indicate how users can opt out.  For example, texting “STOP” would remove the number from receiving further messages and send a confirmation.

We can submit this information on your behalf.   There is a one time registration fee and small monthly charge.

It may take a few days for the information to be validated and activate


It’s important to note that businesses must comply with applicable regulations, such as the Telephone Consumer Protection Act (TCPA) and the Cellular Telecommunications Industry Association (CTIA) guidelines, when using 10DLC numbers for messaging.

Failure to comply with these regulations can lead to penalties, fines, or suspension of messaging services.  In Canada, businesses and organizations need to comply with the Canadian Radio-television and Telecommunications Commission (CRTC) rules and the Canadian Anti-Spam Legislation (CASL) when sending SMS and MMS messages. CASL requires businesses to obtain explicit consent from recipients before sending commercial electronic messages, provide identification information, and offer an opt-out mechanism in every message. 

Penalties for sending unsolicited SMS messages without proper consent can range from $500 to $1,500 per message, per recipient, depending on whether the violation was deemed willful or not.
