10DLC registration for A2P messaging is the The Campaign Registry (TCR) brand and campaign filing that covers Application-to-Person (A2P) programs on United States 10-Digit Long Codes (10DLC). Bing and Google both surface this phrasing next to “A2P 10DLC registration for SMS.”
What Counts as A2P Messaging Here
- Account alerts
- One-time passcodes
- Delivery and appointment notices
- Customer care
- Promotional SMS
If software or a shared template generates the text, treat it as A2P. Do not park that volume on a consumer P2P path.
Filing Still Has Two Layers
Brand identity first. Campaign program second. Number mapping third. Messaging before those steps is unregistered A2P.
Consent remains a Telephone Consumer Protection Act (TCPA) duty. Marketing A2P needs express written consent. Registry approval does not write that record.
