A2P 10DLC Registration for GoHighLevel
US carriers block business SMS sent from unregistered numbers. The message shows as sent, the lead never sees it, and nothing in the dashboard tells you.
A2P 10DLC is the registration system US carriers use to decide whether application to person messaging from a ten digit long code is allowed through. Without a registered brand and campaign, your SMS is filtered before it reaches the handset. GoHighLevel will still show it as delivered to the carrier.
This is the single most common reason a technically correct GoHighLevel build produces no results. The workflows fire, the messages send, and the follow up never lands. Registration is not optional and it is not automatic.
What registration involves
Two separate approvals, in order, plus the caller ID layer on the voice side.
Brand registration
The legal business entity is submitted and verified. EIN, legal name and address must match public records exactly.
Campaign registration
The use case is declared with sample messages, opt in evidence and STOP and HELP handling.
SHAKEN/STIR attestation
Signs outbound calls so they are not presented as likely spam.
CNAM caller ID
Sets the name that displays on the receiving handset.
Why submissions get rejected
Rejections are rarely about the business being illegitimate. They are about evidence.
Entity details do not match
A legal name or address that differs by a word from what the registry holds will fail verification.
Opt in evidence is missing
The form collecting consent has to be publicly reachable and has to state what the contact is agreeing to receive.
Sample messages do not match the use case
Samples that do not resemble the declared campaign type are rejected.
STOP and HELP not handled
Keyword handling must be in place and demonstrable.
What I do on this
Every one of the nine production systems I have built runs on a registered brand and campaign. That includes accounts where the first submission had already been rejected.

Common questions
Can you fix A2P 10DLC registration rejections?
Yes. Most rejections come down to entity details that do not match public records, or opt in evidence that is not publicly reachable. Both are correctable and resubmittable.
Do I need A2P 10DLC if I only send a few messages?
Yes, if you are sending application to person messages to US numbers from a ten digit long code. Volume does not exempt you.
Does this apply to UK businesses?
A2P 10DLC is a US carrier requirement. It applies when you are messaging US numbers, regardless of where your business is registered.
