10DLC applies to U.S. A2P messaging on long code numbers. Brands and campaigns must be registered to support compliant delivery and reduce filtering risk.
Core concepts for program owners and implementation teams.
10DLC is U.S. application-to-person messaging over 10-digit long code numbers with carrier registration and policy requirements.
A brand represents your legal business identity. Campaigns describe message use cases and must align to traffic behavior.
Any business sending A2P traffic on U.S. 10-digit long code pathways should complete registration and campaign approval workflows.
Recommended sequence for onboarding and compliance readiness.
Provide legal entity and contact details with accurate business information for vetting and trust scoring workflows.
Register each message use case with clear consent flow and sample content aligned to actual production behavior.
Associate eligible long code numbers to approved campaigns before launching production traffic.
Maintain opt-in/opt-out controls, content alignment, and campaign hygiene to avoid filtering or enforcement actions.
Operational answers for implementation and support teams.
No. Carriers apply A2P registration requirements beyond marketing traffic. Transactional and operational long-code traffic can still require campaign alignment.
Not always. Toll-free and shortcode programs have different registration and policy paths than 10DLC long-code traffic.
Traffic can be filtered, blocked, or subject to enforcement actions. Maintain registration quality and campaign behavior alignment to reduce risk.
