10DLC registration enforcement is the set of carrier actions applied to unregistered or non-compliant Application-to-Person (A2P) SMS on United States 10-Digit Long Codes (10DLC). T-Mobile, AT&T, and Verizon consume The Campaign Registry (TCR) records and their own codes of conduct.
Enforcement is active. Historical rollout dates do not create a remaining grace period for new programs.
Enforcement Actions
- Message blocking or grey-filtering
- Throughput throttling
- Sender or brand suspension
- Cross-carrier complaint sharing
- Campaign rejection or later deactivation
Unregistered A2P and registered-but-misaligned A2P can both be filtered. Approval does not freeze later enforcement if complaint rates rise or copy drifts.
What Triggers Action After Approval
- STOP failures
- SHAFT or prohibited vertical content
- Use-case drift
- Consent complaints
- Brand data that no longer matches the legal entity
Telephone Consumer Protection Act (TCPA) private actions can run in parallel. Statutory exposure is $500 per message, or $1,500 for willful violations. Carrier filtering and TCPA litigation are different tracks.
FAQ
Who enforces 10DLC registration?
US mobile operators, using TCR data and their messaging policies. The FCC enforces TCPA, not the TCR form itself.
When did 10DLC registration start?
Carriers phased requirements over several years. New traffic should treat registration as currently required.
