A2P 10DLC Registration: Brand, Campaign & Number Setup (2026)

What Is 10DLC?

10DLC (10-Digit Long Code) is a system that allows businesses to send Application-to-Person (A2P) messages using standard 10-digit phone numbers. Introduced by major US carriers, 10DLC requires businesses to register their brand and messaging campaigns before sending texts.

Why 10DLC Registration Matters

Without proper 10DLC registration, your messages may be:

• Blocked entirely by carriers
• Throttled to very low throughput
• Flagged as spam, damaging your sender reputation
• Subject to additional per-message fees

The 10DLC Registration Process

Step 1: Brand Registration

Register your business with The Campaign Registry (TCR). You'll need:

• Legal business name and EIN/Tax ID
• Business address and website
• Contact information
• Business type and vertical

Step 2: Campaign Registration

Register each messaging campaign separately:

• Campaign description and use case
• Sample messages
• Opt-in and opt-out workflows
• Proof of consent collection (this is where OptInFix shines)

Step 3: Carrier Approval

After TCR registration, carriers review and approve your campaigns. Higher trust scores lead to:

• Better message throughput
• Lower filtering rates
• Reduced per-message fees

How Consent Management Affects Your 10DLC Score

Your 10DLC trust score is heavily influenced by your consent management practices. Carriers look for:

• Documented opt-in processes with clear consent language
• Verifiable consent records with timestamps and metadata
• Active opt-out management and suppression lists
• Complaint monitoring and response procedures

Tips for Faster 10DLC Approval

2. Provide clear, specific campaign descriptions
3. Include realistic sample messages
4. Show documented opt-in and opt-out flows
5. Maintain low complaint rates through proper consent
