How to Set Up SMS & Calling in GoHighLevel (A2P 10DLC Registration Guide) - Step 4

Get your business phone number set up and approved for SMS & calling so you can start communicating with customers legally and effectively.

Written by Eric Kelly

Why Do You Need A2P 10DLC Registration?

If you're in North America, regulations require businesses to register their SMS campaigns under A2P 10DLC (Application-to-Person 10-Digit Long Code). This ensures:
Higher SMS deliverability (avoids being flagged as spam)
Compliance with carriers like AT&T & Verizon
Better customer trust & engagement

🚨 Important: If you're outside North America, check your country’s local SMS regulations.


Step 1: Choose & Set Up a Business Phone Number

1️⃣ Go to SettingsPhone Numbers
2️⃣ Click "Add Number"
3️⃣ Search for a local area code (closest to your business)
4️⃣ Select a number with all capabilities (SMS, MMS, voice)
5️⃣ Click "Buy"

🔹 Pro Tip: Your exact area code may not be available. Choose the closest option.


Step 2: Register for A2P 10DLC (Brand Registration)

Once your number is added, you’ll see a message: "A2P Registration Required"

How to Register Your Brand:

1️⃣ Click "Start Registration"
2️⃣ Your business details will auto-fill (from your earlier setup)
3️⃣ Choose "Low Volume Standard" (most businesses send under 6,000 texts/day)
4️⃣ Click "Continue"


Step 3: Register Your SMS Campaign (Use Case)

To get approval, you must submit a use case description and sample messages.

What You Need to Include:

Use Case Description – Explain what types of messages you send (e.g., appointment reminders, marketing, confirmations).
Opt-in & Privacy Policy Link – Carriers require proof that customers agreed to receive messages.
Sample Messages – Provide real examples (GoHighLevel offers templates to use).

🚀 Pro Tip: Use the free A2P Compliance Snapshot that is preloaded in your account!


Step 4: Submit & Wait for Approval

1️⃣ Click "Submit Registration"
2️⃣ Your request will show as "In Progress"
3️⃣ Approval takes 1-3 business days (sometimes up to 2 weeks)
4️⃣ If rejected, check for errors in your EIN, business details, or missing compliance info

Next Step: Once your brand is approved, you’ll complete Campaign Registration (almost identical to this step).
