A2P Text Messaging 2025 Approval Guide

A2P 10DLC might sound like technical jargon, but in 2025, it’s an essential piece of doing business if you’re using text messages to reach your audience in the U.S.

It’s no longer enough to just “have a number” and send messages. U.S. carriers require that your phone number, your business, and even your messaging intent are registered, reviewed, and approved. This shift is designed to reduce spam, improve deliverability, and make business messaging more secure for everyone.

Key Takeaways

• A2P 10DLC registration is mandatory for business texting in the U.S.
• Non-compliance leads to message blocking and higher carrier fees
• You need a live website, privacy policy, terms of service, and compliant forms
• Phone numbers must not be required on forms asking for SMS consent
• Approval depends on accurate business information and clear opt-in methods

What is A2P Text Messaging and Why It Matters in 2025

A2P (Application-to-Person) text messaging allows businesses to send SMS messages to customers using a local 10-digit phone number. But as of 2025, U.S. carriers like AT&T, T-Mobile, and Verizon are enforcing stricter guidelines to prevent spam and misuse.

If you’re not registered, your messages could get blocked or carry heavy fees. This makes A2P registration more than a good idea—it’s non-negotiable for any brand using text messaging to communicate with customers.

Step-by-Step A2P Registration Guide

1. Prepare a Compliant Website

• Your site must be live and functional.
• Include:

Business Name (matching your EIN registration)

Logo

Working Forms (with proper consent checkboxes)

Links to Privacy Policy & Terms of Service

Ensure all forms (website, funnel pages, calendars) requesting a phone number include:

• Two checkboxes:

One for Transactional SMS

One for Promotional SMS

Phone number field must be optional, not required.

2. Create Compliant Policies

• Privacy Policy

  • Must clearly state you do not share user data, especially with affiliates or third parties.

  • Avoid high-risk language related to selling data.

  Terms of Service

  • Add a dedicated SMS section covering:

    • Consent

    • Message frequency

    • Opt-out instructions (e.g., text STOP to unsubscribe)

  Boilerplate templates are available from HighLevel, but they must be customized to your business.

• 

3. Buy a Phone Number

Purchase a number inside HighLevel before registering your brand so you can link it to your campaign.

4. Register Your Brand

Use your CP 575 IRS form details to ensure accuracy:

• Legal Business Name (exact match)

• EIN Number

• Registered Business Address

Mismatched data is the #1 reason for registration failure.

5. Register Your Campaign

Include:

• • Use case (e.g., appointments + promotional offers)

  • Sample messages (e.g., appointment reminders, discounts)

  • Opt-in URLs and explanation of the opt-in process

  • Screenshots of forms, if needed, with proof of compliance

6. Activate Compliance Across All Forms

Ensure your forms—calendars, website, landing pages—all include:

Two opt-in checkboxes

• Optional phone field
• Links to privacy/terms

Failing on even one form can result in campaign rejection or suspension.

7. Set Up Automations

Create flows that:

• Respond to STOP/HELP
• Tag users opting in/out
• Alert your team for compliance

These automations help demonstrate compliance and enhance user experience.
