A2P 10DLC rejected in HighLevel: check the EIN letter first

When A2P 10DLC comes back rejected in GoHighLevel (GHL), first find out whether the brand or the campaign failed. The brand is an identity check: the legal name and EIN on the filing have to match the CP 575 letter, or a 147c letter that replaces it. A campaign rejection can be about consent, the website or the message content instead, and the EIN letter won't fix that.

Brand or campaign: which one failed?

A2P registration has two parts. The brand identifies who is sending. The campaign describes what you send and how people agreed to receive it. They are reviewed separately, and they fail for different reasons.

Open Settings > Phone System > Trust Center and see which one carries the rejection. If it's the campaign, open View required fixes and work through every entry before you resubmit. If it's the brand, the rest of this guide is for you: brand problems are identity problems.

What a brand is checked against

For a US Standard Brand the EIN is required, and a DUNS number is not accepted in its place.

The legal name and EIN on the filing must match the record on the CP 575, the IRS letter that confirms the EIN. If that letter is lost, a replacement 147c letter from the IRS can supply the same registration details.

The legal name means the registered name. A DBA or trade name can't stand in for it, even when it's the name on the sign, the website and every invoice.

The address counts too. A mismatch between the address on the filing and the official record can lower the brand's Trust Score.

Copy the name and EIN from the IRS letter. Not from memory, an invoice or the website.

Compare the filing to the letter, line by line

Do this with the letter in front of you, not from what you remember it says.

  1. Find the CP 575. If it's gone, request a 147c letter from the IRS.
  2. Open the brand details in Trust Center beside the letter.
  3. Check the legal name character by character, exactly as the letter prints it.
  4. Check the EIN digit by digit.
  5. Check the address against the official record and correct any difference.
  6. Resubmit only when every field matches.

Names and addresses that look right but aren't

Each of these is a real name or a real address the business uses every day. None of them is the official identity the brand review looks for:

  • A DBA or trade name in the legal name field.
  • The name from a W-2 or W-9 form instead of the IRS record.
  • A local branch address instead of the registered one.

When every field matches and it still fails

A newly issued EIN may not show up in the verification databases yet, so a brand can be rejected even when the filing matches the letter. In that case, send the federal documentation to HighLevel Support and ask them to review the mismatch.

We can't give you a date for any of this. The carriers review registrations, and the wording of the rejection decides what gets repaired. This isn't legal advice.

Questions

Rejected A2P brands in HighLevel

Can I register the brand under my DBA?
No. The legal name has to be the registered name that matches the IRS record. A DBA or trade name can't replace it, even if it's the name your customers know.
I lost my CP 575. What can I use instead?
Ask the IRS for a 147c letter. HighLevel's guidance accepts it as a replacement source for the registration details the CP 575 would have shown.
Can I use a DUNS number instead of an EIN?
Not for a US Standard Brand. HighLevel requires the EIN for that brand type and doesn't accept DUNS in its place.
Can an address mismatch hurt the brand?
It can. HighLevel's guidance says an address that doesn't match the official record can lower the brand's Trust Score. Use the registered address, not a branch or local office, and correct it before you resubmit.
My campaign was rejected, not my brand. Will the EIN letter help?
Probably not. A campaign rejection is about consent, the website or the message content. Open View required fixes in Trust Center and correct each item it lists before resubmitting.
Everything matches the letter and the brand still failed. Now what?
If the EIN was issued recently, it may not be in the verification databases yet. Send the federal documentation to HighLevel Support for review instead of resubmitting the same details.
