Objective

A registration only affects the numbers attached to it. Assign your phone numbers to a compliance profile or registration so they pick up its benefits, SHAKEN/STIR attestation, a CNAM display name, Voice Integrity protection, or branded calling.

Procedure

1. In the Twilio Console, select Communications in the left sidebar.
2. Select Trust Hub, then either Profiles or Registrations.
3. Open the compliance profile or registration you want to assign numbers to.
4. Select the Assigned phone numbers tab. The numbers already attached are listed there.
5. Select + Add phone numbers.
6. In the panel that opens, find the numbers you want. Use the search box to search by phone number or friendly name, then select the ones to assign.
7. Confirm the assignment. A message tells you the phone number, or numbers, have been successfully assigned to the registration, and they appear in the Assigned phone numbers list.

Additional Information

• Only numbers eligible for that registration are offered. For a Basic branded calling registration, for example, the numbers available are the ones already assigned to its parent Voice Integrity registration.
• If no numbers are available, the panel explains that you need to purchase new numbers or assign existing ones to the connected compliance profile, and offers a link to buy a number.
• Assigning a number to a CNAM registration makes outbound calls from it display your chosen caller name; assigning to a SHAKEN/STIR registration authenticates and verifies its outbound calls.
• For an A2P 10DLC Campaign, senders come from its Messaging Service, so the tab also offers Add numbers to messaging service.
