T-Mobile 10DLC Framework
Mandatory registration requirements and carrier-specific compliance standards
T-Mobile enforces mandatory 10DLC registration for all business messaging with zero exceptions. The carrier operates edge server filtering systems that analyze message content in real-time, throttle throughput for policy violations, and coordinate cross-carrier enforcement actions. DUNS-verified brand registration significantly improves approval speed and trust score assignment.
Zero Tolerance Policy
100% of business messaging requires 10DLC registration. Unregistered traffic faces immediate throttling or blocking.
Edge Server Filtering
Real-time content analysis blocks prohibited content at network perimeter before delivery to subscribers.
Cross-Carrier Coordination
Violation reports shared with AT&T and Verizon for network-wide enforcement and blocklisting.
T-Mobile's Enforcement Philosophy
Critical Success Factors
- DUNS Registration Priority: Obtain DUNS number before brand registration for +10-15 trust score points
- Content Policy Compliance: Zero tolerance for cannabis/CBD, SHAFT content requires strict message validation
- Brand-Website Alignment: Legal business name must match domain registration and state filings exactly
- Use Case Accuracy: Campaign use case must precisely describe actual message content to avoid rejection
