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.

Term Definition Business Impact
10DLC 10-Digit Long Code messaging framework for business communications Enables higher throughput than shared short codes
Brand Registration Process of verifying business identity with TCR Required before campaign creation; affects trust score
Campaign Specific messaging use case registered with TCR Determines message content rules and throughput limits
Trust Score TCR-assigned rating (0-100) based on brand verification Higher scores enable faster approval and increased throughput

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.

Regulatory Authority

  • ✓
    CTIA-Mandated: The Cellular Telecommunications Industry Association established 10DLC requirements as industry standard
  • ✓
    Carrier-Enforced: T-Mobile, AT&T, and Verizon enforce 10DLC through message filtering and throughput controls
  • ✓
    Industry-Wide: All messaging service providers must comply with 10DLC requirements

Business Impact of Non-Compliance

Non-Compliance Consequences

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

  • Message blocking or filtering
  • Severe throughput throttling (1 message/minute or less)
  • Sender reputation damage
  • Potential service suspension

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 score (0-100) based on verification results and reputation signals

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
  • 3
    Opt-In Process: Describe how customers consent to receive messages
  • 4
    Carrier Review: T-Mobile, AT&T, and Verizon review and approve campaign details
Timeline Expectations

Brand Registration: 1-3 business days for automated approval; 5-10 days if manual review required

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 increased message throughput.

Score Range Approval Likelihood Throughput Limit Review Process
75-100 High (>95%) Up to 4,500 msg/min Automated approval
50-74 Medium (70-90%) Up to 600 msg/min Automated + spot checks
25-49 Low (40-60%) Up to 60 msg/min Manual review required
0-24 Very Low (<30%) Blocked pending review Manual + carrier escalation

Trust Score Improvement Strategies

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.

Primary Use Case Categories

  • 📢
    Marketing: Promotional content, sales offers, product announcements (highest scrutiny)
  • 🔔
    Customer Care: Support communications, account notifications, service updates
  • 🔐
    2FA: Authentication codes, login verification (fastest approval)
  • 📋
    Mixed: Combination of multiple message types (requires detailed justification)
  • 🚨
    Emergency: Critical safety notifications (special approval process)
