A2P 10DLC: The SMS Compliance Guide for Investors

If you are sending text messages to motivated sellers, you must be A2P 10DLC compliant. Non-compliant messages get filtered or blocked by carriers.

What Is A2P 10DLC?

A2P stands for Application-to-Person. 10DLC stands for 10-Digit Long Code (your regular phone number). Together, it is the carrier-approved system for sending business text messages from standard phone numbers.

Why It Matters

Before A2P 10DLC, anyone could blast SMS from any number. Carriers cracked down. Now:

  • Unregistered messages have 80-95% filter rates
  • Registered messages have 5-15% filter rates
  • Carriers can fine you for non-compliance
  • Your number can be permanently blocked

Step-by-Step Setup

Step 1: Register Your Brand

Submit your business information to The Campaign Registry (TCR):

  • Legal business name (must match LLC/EIN exactly)
  • EIN (federal tax ID)
  • Business address
  • Website URL (must match your business)
  • Business type and vertical

Critical: Your LLC name, EIN, and domain must align. Mismatches cause rejection.

Step 2: Register Your Campaign

Describe your use case:

  • Use case: Real estate investment marketing
  • Sample messages: Include 2-3 example texts
  • Opt-out language: Must include STOP to unsubscribe
  • Volume: Estimated monthly message count

Step 3: Domain Verification

Carriers verify your website domain matches your brand. Your website must:

  • Be live and accessible
  • Show your business name
  • Include contact information
  • Have privacy policy and terms of service

Step 4: Carrier Approval

After TCR and campaign registration, carriers review and approve. Timeline: 1-3 weeks.

Common Rejection Reasons

  1. LLC name does not match EIN records
  2. Domain does not match business name
  3. Sample messages too aggressive or misleading
  4. Missing opt-out language
  5. Website not live or incomplete
