10 DLC Number Linking Registration Guide


Note: This feature is currently in beta access only.

Step 3 of 10 DLC registration is linking your numbers to campaigns. This is the final step where you will map your numbers to an approved campaign ID.


You can either purchase new phone numbers or use the ones you already have under your account.

Access the Brands and Campaign page and click on your campaign. On the Numbers tab, you will see a list with all the US phone numbers assigned to your account:


On this page you will be able to Link or Unlink numbers with your campaign.

When you click Link you will be able to choose if you want your number to be HIPAA compliant or not. Note that if you want to be HIPAA compliant you need to first reach out to your Account Manager.


After you request to Link a number to a campaign, the process will take a few minutes to complete. During this time you will see a pending status of your number linking.

SMS traffic will be automatically changed to 10 DLC as soon as the number linking to the campaign is complete.

Note that a phone number can only be linked to one campaign.

Rejected Numbers

If the number goes to status rejected after requesting to link it to a campaign, like in the image above, you should retry to link it again in two hours by clicking Unlink and then Link back to the same campaign. If this still does not work for you or you receive any other error message, submit a support request.
