A2P 10DLC registration for SMS is the The Campaign Registry (TCR) filing that covers Application-to-Person (A2P) text messages sent from a United States 10-Digit Long Code (10DLC). Searchers also use “10DLC SMS registration” for the same event.
RCS, voice, and email are outside this filing. Toll-free SMS and short-code SMS use other tracks.
Why SMS Is Named in the Query
Most CSPs first surfaced the requirement on SMS products. Console banners read “A2P 10DLC registration required” next to SMS services. The registry record still has two layers: brand identity and campaign program.
MMS attached to the same 10DLC campaign follows the approved use case. Do not assume a second registry product is required for MMS when the CSP maps it to the same campaign. Confirm that mapping in the live console.
SMS Content the Campaign Must Describe
- Message purpose
- Expected frequency
- Opt-in source
- STOP and HELP behavior
- Sample copy that matches production SMS
Telephone Consumer Protection Act (TCPA) consent still governs marketing SMS. Registry approval does not write the consent record for you.
10DLC SMS Registration Versus Other Sender Types
| Sender type | Typical registration track |
|---|---|
| US 10-digit long code A2P SMS | TCR brand + campaign |
| US toll-free SMS | Toll-free verification |
| Short code SMS | Short-code application |
| Consumer P2P SMS | Not an A2P campaign |
Mis-tagging the sender type wastes a filing cycle.
