GoHighLevel A2P Registration: (Helpful Tutorial)

If you're using GoHighLevel to send SMS or MMS messages to your leads or customers, there's one important step you can't ignore – A2P Registration.

With the rise of spam and SMS regulations in the U.S., mobile carriers now require all businesses to register before sending texts through software like GoHighLevel.

This process is known as A2P 10DLC registration (short for Application-to-Person via 10-digit long code).

In this helpful tutorial, you’ll learn exactly what A2P registration is, why it matters, and how to complete it step-by-step inside your GoHighLevel dashboard.

Whether you're a digital agency, local business, or SaaS reseller, this guide will help you stay compliant, improve message delivery, and avoid blocked texts.

In this guide, I'll walk you through the process so you can start texting the right way – with full compliance and confidence.

Let's start!

What is A2P Registration in GoHighLevel?

A2P registration in GoHighLevel refers to the process of registering your business and phone numbers with mobile carriers to legally and reliably send SMS and MMS messages in the United States.

A2P stands for Application-to-Person, and it involves using software (like GoHighLevel) to send text messages to people.

Because of rising spam and fraud through SMS, U.S. carriers now require all businesses to register their brand and messaging campaigns before sending texts from local (10-digit) phone numbers – known as A2P 10DLC registration.

Here’s what this means for you:

• Your business must be verified (with basic legal info like name, EIN, and website).
• Your SMS campaign type must be declared, such as appointment reminders, promotions, or lead follow-ups.
• All this happens directly in GoHighLevel through the Trust Center under the A2P registration tab.

Once you’re approved, you get:

• Higher message delivery rates
• Fewer blocked or filtered texts
• Full compliance with U.S. carrier rules

If you plan to use GoHighLevel for texting leads, clients, or customers, A2P registration is not optional – it's essential.

Why You Need A2P Registration

If you're planning to send SMS or MMS messages using GoHighLevel, A2P registration isn’t just a recommendation – it's a requirement.

Here’s exactly why you need it:

• ✅ Compliance with Carrier Regulations

Mobile carriers in the U.S. (like AT&T, T-Mobile, and Verizon) now require all businesses using SMS to register under A2P 10DLC.

Without this registration, your messages could get flagged, delayed, or outright blocked.

• 🚫 Avoid Message Filtering and Deliverability Issues

Unregistered numbers face heavy message filtering and low delivery rates. A2P registration ensures your texts reach your customers reliably, especially for important messages like:

• Appointment reminders
• Order updates
• Lead follow-ups
• Promotional campaigns

• 🔒 Build Trust with Customers

Registered A2P numbers are seen as more legitimate. This boosts your brand's reputation and makes recipients more likely to engage with your texts, improving overall conversion rates.

• ⚡ Access to Full SMS Functionality in GoHighLevel

Until you complete your A2P registration, GoHighLevel may limit your ability to send SMS/MMS messages.

To unlock full texting capabilities across workflows, campaigns, and automations, you must register your business.

• 📈 Better Performance, Fewer Headaches

A2P-registered numbers get:

• Higher throughput (faster sending rates)
• Better deliverability
• Carrier trust scores for scaling campaigns

Bottom line?
If you're using GoHighLevel’s texting tools to reach leads or clients in the U.S., A2P registration is critical to protect your delivery, reputation, and results.

What You’ll Need Before Starting

Before you begin your GoHighLevel A2P registration, it’s important to gather a few key details to make the process smooth and successful.

Here's what you'll need:

• ✅ 1. A GoHighLevel Account

To register for A2P messaging, you must already have an active GoHighLevel account. The A2P setup is done directly inside your GoHighLevel dashboard under the Phone Numbers section.

• 🏢 2. Your Business Information

You’ll need valid business credentials, including:

• Business name
• EIN (Employer Identification Number) or Tax ID (for U.S. businesses)
• Business address
• Website URL

This information is used to register your business with The Campaign Registry (TCR) — the official body that handles A2P messaging approvals.

• ☎️ 3. A Registered Phone Number

The number you plan to use for messaging must be a dedicated business line — typically a 10-digit long code (10DLC). This number must be connected to your GoHighLevel account.

• 📢 4. Campaign Use Cases

You’ll be asked to specify how you plan to use SMS messaging. Be prepared to describe your campaign use cases, such as:

• Appointment reminders
• Order/shipping updates
• Marketing promotions
• Internal alerts
• Lead follow-ups

Providing this detail ensures that your application is clear and more likely to be approved.

Pro Tip:
Make sure the information you submit is consistent with your public-facing brand (i.e., your website and business listing). Discrepancies can lead to delays or rejections.

With these items ready, you’ll breeze through the A2P registration and unlock full messaging capabilities in GoHighLevel.

Your sample messages and campaign purpose must follow CTIA and carrier guidelines.

Common red flags include:

• Promoting illegal or restricted products (e.g., cannabis, firearms)
• No clear opt-in or opt-out language
• Spamming or misleading offers

Fix:
Use clean, compliant messaging with proper disclosures. Include lines like:

“Reply STOP to unsubscribe.”

If your campaign gets rejected:

• Log into GoHighLevel
• Go to Settings → Phone System Settings → A2P Registration
• Look for the rejection reason (shown next to the campaign)

Bonus Tip: Make the Most of Your SMS Campaigns

Once your A2P registration is approved, don’t stop there. To truly maximize the power of your SMS efforts in GoHighLevel.

Here’s how to level up your campaigns:

✅ 1. Segment Your List

Don’t send the same message to everyone. Break your contact list into groups based on:

• Buyer behavior
• Location
• Engagement level
• Lead source

Example: Send personalized reminders to booked appointments, and separate offers to cold leads.

⚙️ 2. Use Automation (With Compliance in Mind)

Set up smart automations in GoHighLevel using workflows to:

• Send SMS immediately after a form is submitted
• Trigger follow-ups if a reply isn't received
• Add opt-out logic automatically

Remember: Always include opt-out language like “Reply STOP to unsubscribe” in your messages.

📊 3. Monitor Deliverability Regularly

Use GoHighLevel’s reporting to track:

• Delivery rates
• Open/read rates
• Opt-outs and bounces

If numbers drop, review your message content and sending patterns to stay compliant and effective.

Smart SMS strategy = better engagement + fewer issues + higher ROI.
