Quick answer: A2P (Application-to-Person) verification is required by carriers for any business sending SMS through platforms like GoHighLevel. Without it, your texts get blocked or filtered as spam. The process takes 2-4 weeks if done right, and most rejections come from simple mistakes we'll cover below.
What Is A2P Verification?
A2P stands for Application-to-Person messaging. It's any SMS sent from a software application (like GoHighLevel) to a person, rather than from one person to another.
If you're using GoHighLevel's SMS features — appointment reminders, follow-ups, broadcast campaigns, review request texts — you need A2P verification. Period.
Why It Matters for GHL Agencies
- ▪Without A2P: Your SMS messages get blocked, filtered as spam, or never delivered
- ▪With A2P: Your messages reach customers' inboxes with high deliverability
- ▪Carriers are cracking down: Since 2024, AT&T, T-Mobile, and Verizon have aggressively filtered unverified A2P traffic
- ▪Your clients will blame you: If their appointment reminders stop working, you're the first call
Who Needs A2P Verification?
- ▪Anyone using GoHighLevel SMS features
- ▪Agencies sending texts on behalf of clients
- ▪Businesses using automated SMS sequences
- ▪Anyone sending more than 100 messages/day from a single number
If you're not sure: You need it. Every business using GHL's SMS features needs A2P verification.
The A2P Verification Process (Step by Step)
Step 1: Register in The Campaign Registry (TCR)
GoHighLevel uses The Campaign Registry (TCR) for A2P registration. Here's how to start:
- ▪Log into your GoHighLevel account
- ▪Go to Settings → Phone Numbers → A2P Registration
- ▪Click "Start Registration"
- ▪You'll be redirected to TCR's portal
Step 2: Gather Your Documents
This is where most people fail. You need:
| Document | Why | Tips |
|---|---|---|
| EIN / Tax ID | Proves you're a real business | Use your LLC or Corp EIN, not SSN |
| Business address | Must match your registration | No PO boxes |
| Business website | Must be live and show your business | Not a "coming soon" page |
| Sample messages | Shows what you'll send | Must include opt-out language |
| Opt-in method | How you collect phone numbers | Web form, keyword, verbal consent |
Step 3: Choose Your Use Case
TCR categorizes messages into use cases:
| Use Case | Description | Approval Difficulty |
|---|---|---|
| Marketing | Promotional texts, offers | Medium |
| Transactional | Appointment reminders, order updates | Easy |
| Mixed | Both marketing and transactional | Medium-Hard |
Pro tip: If you're an agency, register under Transactional first (easier approval), then add Marketing later.
Step 4: Submit Sample Messages
You must provide 3-5 sample messages you'll actually send. Each must include:
- ▪Your business name
- ▪Clear description of what you're offering
- ▪Opt-out language (e.g., "Reply STOP to unsubscribe")
- ▪Help information (e.g., "Reply HELP for help")
Bad example:
Hey! Check out our new product. Buy now!
Good example:
Hi [Name], this is [Business Name]. Your appointment is confirmed for [Date] at [Time]. Reply STOP to unsubscribe.
Step 5: Wait for Approval
- ▪Timeline: 2-4 weeks (sometimes faster)
- ▪You'll get: Approved, Rejected, or Pending More Info
- ▪If rejected: Fix the issue and resubmit (most rejections are fixable)
Top 5 Reasons A2P Applications Get Rejected
1. Website Doesn't Match Business
Your website must:
- ▪Show your actual business (not a template)
- ▪Have a privacy policy
- ▪Have a terms of service
- ▪Match the business name on your registration
2. Missing Opt-Out Language
Every sample message MUST include opt-out instructions. Carriers are strict about this.
3. Sample Messages Are Too Vague
"Don't miss our sale!" gets rejected. "Hi Sarah, Orometa here — our annual webinar on marketing automation is live this Thursday. Reply STOP to opt out." gets approved.
4. EIN Doesn't Match
The Tax ID you enter must exactly match what's on file with the IRS. No typos.
5. Using a Personal Number
You can't register A2P on a personal cell phone number. You need a dedicated business number through GoHighLevel.
How Long Does A2P Verification Take?
| Stage | Timeline |
|---|---|
| Document preparation | 1-2 days |
| TCR submission | Same day |
| Carrier review | 5-14 business days |
| Approval/rejection | 1-3 days after review |
| Total | 2-4 weeks |
Speed tip: Have all documents ready before you submit. The #1 cause of delays is back-and-forth requesting missing information.
A2P for Agencies: Managing Multiple Clients
If you're an agency managing SMS for multiple clients, you have two options:
Option 1: Register Each Client Separately
- ▪Each client gets their own A2P registration
- ▪Best for: Large clients with high volume
- ▪Pros: Dedicated numbers, clean separation
- ▪Cons: More paperwork, longer setup
Option 2: Register Under Your Agency
- ▪You register once, send on behalf of clients
- ▪Best for: Small businesses, lower volume
- ▪Pros: Faster setup, less paperwork
- ▪Cons: All messages come from your brand name
Our recommendation: Start with Option 2 (agency registration) for speed, then migrate high-volume clients to Option 1.
Common A2P Issues & Fixes
| Issue | Fix |
|---|---|
| Messages going to spam | Ensure A2P is approved AND number is properly configured in GHL |
| Registration pending for weeks | Check TCR dashboard for "action required" — most delays are missing info |
| Client's messages blocked | Verify the client's number is registered, not your agency number |
| Can't send MMS | A2P verification covers SMS only — MMS requires separate registration |
| Need to change use case | Submit a new registration (don't edit the existing one) |

FAQ
What happens if I don't complete A2P verification? Your SMS messages will be blocked or filtered as spam by carriers. GoHighLevel may also restrict your SMS features until verification is complete.
Do I need A2P for email too? No. A2P verification is specifically for SMS/MMS. Email has its own authentication protocols (SPF, DKIM, DMARC) which GoHighLevel handles separately.
Can I use my existing phone number? Maybe. If the number is already registered with a carrier and not associated with another A2P campaign, you can transfer it. Otherwise, get a new number through GoHighLevel.
How much does A2P verification cost? GoHighLevel includes A2P registration at no additional cost. TCR charges a one-time registration fee (typically $15-45 per number). Carriers may charge a monthly A2P fee ($1-15/month per number).
What if my application gets rejected? Most rejections are fixable. Common fixes: update your website, add opt-out language to sample messages, or correct your EIN. You can resubmit immediately after fixing the issue.
