# Register an existing US long number

If you have **existing US long numbers** (i.e., numbers you've purchased before the 10DLC regulations were introduced), you are also required to link each number to a registered brand and campaign.

## Register an existing US long number

1. Navigate to *My Workspace --> Long Numbers & Short Codes*. 
2. You will see a *Link to 10DLC* button next to the US long numbers that require linking.
