A2P 10DLC Rejection Reasons: 12 Fixes for HighLevel Agencies

Getting an A2P 10DLC campaign rejected feels like a punch in the gut. You spent an hour filling out forms for your client, you waited days for a response, and now you’re staring at a vague error code with no idea what to fix.

This guide walks through every common rejection reason we see in HighLevel and gives you the exact fix — so you can resubmit with confidence.

Why A2P 10DLC campaigns get rejected

The Campaign Registry (TCR) reviews every brand and campaign submission against a strict checklist. If anything doesn’t match, you get rejected. The frustrating part is that TCR stops reviewing the moment they find the first issue — so fixing one problem doesn’t guarantee approval. You need to submit a complete, compliant package on the first try.

Here are the 12 most common rejection reasons and how to fix each one.

1. EIN mismatch with legal business name

The error: “Business registration number does not match legal name.”

The fix: Open your client’s CP 575 EIN Confirmation Letter from the IRS and copy the legal business name exactly as it appears there — including punctuation, “Inc.”, “LLC”, and capitalization. Even a missing comma can trigger a rejection.

Pro tip: If your client doesn’t have their CP 575 letter, they can request a confirmation letter (147C) by calling the IRS at 800-829-4933.

2. Website is missing or returns an error

The error: “Website URL is invalid or unreachable.”

The fix: The website you submit must:

Be publicly accessible (no password protection)
Return HTTP 200 (not a 404 or redirect loop)
Have working HTTPS (no SSL warnings)
Match the brand name and business

If your client doesn’t have a website, you need to build one. A compliance-focused landing page is not enough — TCR wants to see a real, multi-page business website. A2P Genius generates a TCR-compliant six-page website automatically from a webhook payload.

3. Missing privacy policy

The error: “Privacy policy not found or non-compliant.”

The fix: Your client’s website must have a privacy policy page that explicitly states the following:

SMS opt-in data will not be shared with third parties for marketing or promotional purposes
How phone numbers collected via the website will be used
How users can opt out

The policy must live on the same domain as the website (not a link to a PDF or a third-party service). It must be linked from the same page that collects the phone number.

4. Missing or non-compliant SMS opt-in language

The error: “Opt-in consent is insufficient or missing.”

The fix: Your opt-in form needs a checkbox (not pre-checked, not required to submit the form) next to disclosure language like:

By checking this box, you consent to receive SMS notifications from [Business Name]. Message frequency varies. Message and data rates may apply. Reply STOP to unsubscribe, HELP for help.

All six elements must be present: business name, frequency, rates disclosure, opt-out instructions, help instructions, and explicit consent.

5. Sample messages don’t match the use case

The error: “Sample messages inconsistent with campaign use case.”

The fix: Your sample messages must:

Match the campaign use case you selected (don’t use OTP-style messages in a Marketing campaign)
Include your client’s actual business name (not a placeholder like [BUSINESS NAME])
Include opt-out language like “Reply STOP to unsubscribe”
Use brackets to show templated fields like {{first_name}} or {{appointment_time}}

Submit at least two sample messages, and at least one should include the business name plus an opt-out.

6. Brand vs. website mismatch

The error: “Brand name does not match website content.”

The fix: The business name you submit must appear prominently on the website homepage. If the brand is “Acme Marketing LLC” but the website says “Acme Digital,” TCR will reject it. Make sure the site’s title tag, footer, and about page all reference the registered brand name.

7. Content violations (SHAFT categories)

The error: Error code 30883 or specific granular codes (30884, 30885, 30897) after March 2026.

The fix: A2P messaging cannot mention or promote:

Sex — adult content, dating, escorts
Hate — hate speech or discrimination
Alcohol, firearms, tobacco
Tobacco and vaping products
Cannabis (even in states where it’s legal)
Payday loans, debt collection
Gambling

If your client’s business touches any of these categories, A2P 10DLC approval is unlikely or impossible.

8. PO Box used for business address

The error: “Business address must be a physical location.”

The fix: Use a physical street address on both the registration and the website. A home address is fine; a PO Box is not.

9. Missing terms of service

The error: “Terms of service page not found.”

The fix: Terms of service are required alongside the privacy policy. Both must be linked from the same page where the phone number is collected. A2P Genius generates both automatically.

10. Forbidden use case

The error: “Campaign use case not permitted.”

The fix: Some use cases are outright banned for A2P 10DLC. Notably, you cannot register a campaign for:

Lead generation to third parties
Affiliate marketing
Cold outreach where consent wasn’t collected from the recipient directly

If your campaign description mentions any of these, reword it to focus on your client’s direct relationship with their own customers.

11. Brand is not a US business

The error: “Brand could not be verified as a US entity.”

The fix: A2P 10DLC is a US standard. If your client is Canadian, you may need to use the Sole Proprietor brand type. If they’re outside North America, A2P 10DLC may not apply.

12. Inconsistency in campaign description

The error: “Campaign description does not match sample messages or use case.”

The fix: Rewrite the campaign description to clearly explain:

What kind of messages will be sent
Who they’ll be sent to
How those recipients gave consent
An example of the message flow

Your description should match the sample messages exactly. If your description says “appointment reminders” but your samples are promotional, TCR will reject it.

The fastest way to avoid all 12 rejections

Every single one of these rejection reasons comes down to mismatches between what TCR expects and what your submission shows. Manual form-filling makes these mistakes almost inevitable — especially when you’re registering A2P for dozens of HighLevel sub-accounts.

A2P Genius solves this by generating a TCR-compliant website and pre-filling every field of the registration form automatically, based on a simple client onboarding form. The business name matches the EIN, the website has all required pages, the opt-in language is compliant, and the sample messages match the use case — every time.
