10DLC number registration is the step that attaches a United States 10-Digit Long Code (10DLC) to an approved The Campaign Registry (TCR) campaign. Purchasing the number from a Campaign Service Provider (CSP) is not registration. Unmapped numbers remain unregistered Application-to-Person (A2P) sources.
Correct Order
- File the brand.
- File the campaign.
- Wait for approved status on both records.
- Assign specific 10DLC numbers to that campaign in the CSP console or API.
- Send production A2P only from mapped numbers.
Assigning a number to the wrong campaign recreates use-case misalignment at the traffic layer.
What Reviewers Do Not See
TCR reviews brand and campaign packages. Number inventory lives at the CSP. A large number pool does not raise a trust score. Clean identity and a matching program do.
FAQ
Do I register every 10DLC separately with TCR?
You register the brand and campaign, then map numbers. You do not open a new brand for every DID in a standard program.
Can I move a number to a new campaign?
Follow the CSP’s reassignment rules. Treat a new use case as a new campaign first.
