GoHighLevel A2P 10DLC registration guide
A practical walkthrough for preparing a GoHighLevel A2P 10DLC registration: business identity, brand registration, campaign use case, opt-in evidence, sample messages, website compliance and what to check when a campaign is rejected.
What A2P 10DLC registration is doing
A2P 10DLC is the registration framework used for application-to-person messaging over U.S. 10-digit long-code numbers. The process identifies the business sending messages (the Brand) and the messaging purpose, consent flow and message behavior (the Campaign). Registration is not just a formality: the submitted information needs to match the real business, website and customer opt-in journey.
GoHighLevel A2P registration: the practical sequence
1. Verify the business identity
Use the exact legal business information that can be verified. Keep the legal name, tax/registration details, address, website and contact information consistent with the business's public presence.
2. Prepare the website before submission
The website should make the business identifiable and support the stated opt-in process. If a web form collects phone numbers for SMS, the consent language and surrounding disclosures should be visible and accurate.
3. Register the brand
The Brand identifies who is sending the messages. Complete this using the correct business type and verifiable information rather than abbreviations or details that conflict with public records.
4. Define the campaign use case
Explain what messages will be sent, who receives them and why. A vague description such as “marketing” does not explain the actual customer journey.
5. Document exactly how users opt in
Describe the real consent path: web form, booking flow, keyword, paper form or another method. The reviewer needs to be able to understand and, where applicable, verify that flow.
6. Write representative sample messages
Samples should match the campaign description and identify the sender. They should reflect the messages the business genuinely intends to send, including applicable opt-out language.
7. Submit and review the result
After submission, watch the Trust Center status. If a campaign is rejected, use the stated reason to correct the underlying registration, consent, website or message issue before resubmitting.
8. Link approved messaging correctly
Approval is only one part of the setup. Make sure the relevant number and messaging configuration are associated correctly before assuming an approved campaign is ready to send.
Opt-in and consent: where many submissions go wrong
The campaign registration should explain how a person knowingly agrees to receive the specific type of SMS being sent. If the registration says users opt in through a website, the website should support that claim. Twilio's current guidance says the message flow should describe how end users opt in and, for website opt-in, provide the relevant website and privacy-policy information. It also emphasizes that consent cannot be solicited through an SMS sent before the recipient has consented.
Make the consent specific
Don't rely on a generic form submission to imply SMS consent. The user journey should make clear what they are agreeing to receive.
Keep the registration and website aligned
If your campaign description says customers opt in through a booking form, reviewers should not find a completely different process when they inspect the website.
Privacy and terms matter
For web-based opt-in, make the relevant privacy policy and terms accessible. Current carrier/TCR guidance scrutinizes these URLs and the mobile-data disclosures attached to the consent flow.
Document non-public opt-in
If consent happens somewhere reviewers cannot access, use the evidence method permitted by your provider, such as a public screenshot or demonstration of the actual flow.
How to write the campaign description and sample messages
Treat the campaign description, use case, opt-in explanation and message samples as one story. If those pieces contradict one another, the registration becomes harder to verify.
Campaign description
State the sender, the recipients and the reason messages are sent. Describe the actual purpose rather than using a one-word label.
Sample messages
Use realistic examples that align with the campaign. Identify the business/brand, represent variable content clearly and include appropriate opt-out instructions.
Why a GoHighLevel A2P campaign may be rejected
A rejection should be diagnosed, not guessed at. Common problem areas include inconsistent business information, an unclear or unverifiable opt-in path, missing website disclosures, campaign details that do not match the stated use case, and sample messages that do not represent the campaign properly.

Frequently asked questions
Do I need A2P 10DLC for GoHighLevel SMS?
