What is The Campaign Registry (TCR)?

The Campaign Registry (TCR) is the industry-authorized entity that manages 10DLC (10-Digit Long Code) brand verification and campaign approval for Application-to-Person (A2P) messaging in the United States. Established under CTIA guidelines and operated through carrier agreements, TCR validates sender identity and assigns trust scores that determine message throughput and approval likelihood.

Why TCR Exists

TCR was created to reduce spam and fraud in business messaging while enabling legitimate organizations to reach customers effectively. By requiring brand verification and campaign approval, TCR helps carriers distinguish between legitimate business communications and unwanted spam.

Key Terms

Understanding the 10DLC Framework

10DLC messaging requires all commercial senders to register their brand and campaigns with TCR before sending messages. This framework applies to all Application-to-Person (A2P) messaging in the United States, including marketing, notifications, alerts, and customer service communications.

CTIA-Mandated

The Cellular Telecommunications Industry Association established 10DLC requirements as the industry standard.

Carrier-Enforced

T-Mobile, AT&T, and Verizon enforce 10DLC through strict message filtering and throughput controls.

Industry-Wide

All messaging service providers (Twilio, Sinch, Vonage, etc.) must comply with these 10DLC requirements.

Business Impact of Non-Compliance

Messages sent without proper 10DLC registration face significant delivery issues:

• Complete message blocking or heavy filtering
• Severe throughput throttling (1 message/minute or less)
• Sender reputation damage affecting future approvals
• Potential service suspension and $10,000 carrier fines

TCR Registration Process

TCR registration involves two distinct phases: Brand Registration (verifying business identity) and Campaign Registration (defining specific messaging use cases). Both are required before sending commercial messages.

Phase 1: Brand Registration

• 1

  Business Verification: Provide legal business name, EIN/Tax ID, business type, and registration details.

• 2

  Contact Information: Submit business address, phone number, and authorized representative contact.

• 3

  External Verification: TCR validates information against DUNS database and public business records.

• 4

  Trust Score Assignment: TCR assigns a score (0-100) based on verification results.

Phase 2: Campaign Registration

• 1

  Use Case Selection: Choose appropriate category (marketing, mixed, customer care, etc.).

• 2

  Sample Messages: Provide representative examples of actual message content containing opt-outs.

• 3

  Opt-In Process: Describe in detail how customers provide consent to receive your messages.

• 4

  Carrier Review: T-Mobile, AT&T, and Verizon review and approve the campaign details manually.

Timeline Expectations

Brand Registration: 1-3 business days (automated); 5-10 days if manual review is triggered.

Campaign Registration: 1-10 business days depending on trust score and use case complexity.

Understanding Trust Scores

Trust scores are TCR's primary mechanism for determining brand credibility and campaign approval likelihood. Scores range from 0-100, with higher scores enabling faster approvals and significantly increased daily message throughput.

Trust Score Improvement Strategies

• Obtain DUNS Number: Adds 10-15 points through enhanced business verification.
• Age Business Domain: Older domains (6+ months) demonstrate business stability.
• Build Online Reviews: 4+ star average across review platforms verifies authenticity.
• Start Conservative: Begin with low-risk use cases (2FA, notifications) before marketing.

Campaign Use Cases

TCR defines specific use case categories that determine campaign approval requirements, throughput limits, and content restrictions. Selecting the appropriate use case is critical for approval success.

Carrier-Specific Requirements

While TCR provides the foundation for 10DLC registration, each major carrier (T-Mobile, AT&T, Verizon) has additional requirements and enforcement policies that affect message delivery and approval success.

T-Mobile Requirements

• Mandatory DUNS-verified brand registration for max throughput.
• Strict SHAFT content enforcement with $10,000 penalties.
• Real-time filtering with immediate throttling for violations.

AT&T Requirements

• ML-based spam detection with behavioral pattern analysis.
• Enhanced scrutiny for financial services and crypto content.
• 100% active blocking of unregistered legacy long codes.

Verizon Requirements

• EIN/Tax ID verification required for all commercial registrations.
• Heightened scrutiny for debt collection and legal services.
• Volume spike monitoring (>300%) with automatic suspensions.

Common Registration Mistakes

Critical Mistakes to Avoid

These errors cause 80% of TCR rejections and can delay approval by weeks, costing $15 per resubmission attempt:

• Inconsistent Business Information: Name, address, or EIN mismatches between TCR and public records (IRS/DUNS).
• Vague Sample Messages: Providing generic or placeholder content (e.g., "Hi customer") instead of actual, structured message examples with STOP language.
• Inadequate Opt-In Description: Unclear or incomplete descriptions of exactly how and where consent is captured.
• Missing Privacy Clause: Failing to explicitly state in your privacy policy that SMS consent is NOT shared with 3rd parties.

Your Next Steps

Now that you understand TCR fundamentals, follow this sequence to begin your registration process and ensure compliance success without wasting time or resubmission fees.
