A2P 10DLC registration in HighLevel
If a business texts US numbers from a regular 10-digit local number, it needs an approved A2P 10DLC brand and campaign, and the number must be linked to that campaign before sending. [What is A2P 10DLC: Brand and Campaign Registration, updated 2026-09-04; checked 2026-10-25] Here is the process, what it costs, and how to avoid the usual rejections.
Where it lives
In the sub-account: Settings > Phone System > Trust Center, then the A2P messaging section. Each business registers its own brand with its own legal details.
Step 1: choose the brand type
| Brand type | Who it's for | Registration fee (one-time) | Campaign fee (monthly) |
|---|---|---|---|
| Sole Proprietor | Individuals or one-person businesses with no EIN or other business registration number. One number can be linked. | $22.5 (includes $3 non-refundable Fast Track) | up to $2.10 |
| Standard, Low Volume | Businesses with an EIN/Tax ID and lower daily volume | $22.5 | $1.50–$10.50 |
| Standard, High Volume | Businesses with an EIN/Tax ID and higher volume | $64 | $10.50 |
[LC Phone Pricing & Billing Guide, updated 2026-10-12; checked 2026-10-25] A business that has a Tax ID must register as a Standard brand, not Sole Proprietor. When re-billing is enabled, a 5% markup applies to these pass-through fees at the sub-account level.
Step 2: brand details (must match tax records)
- Legal business name and EIN exactly as on IRS records (an LLC's full legal name, including "LLC"). Uploading the CP-575 letter can pre-fill fields.
- Registered address, business type, industry, region.
- An authorised contact: name, a phone they answer, an email they monitor, job title.
- A live public website that names the business and matches the brand details.
New EIN? A newly issued EIN that hasn't propagated yet is a listed rejection reason. If the EIN is only days old, wait before submitting.
Step 3: campaign
You choose between Chat Widget Setup (the default: HighLevel generates an opt-in widget and pre-fills most fields) and Manual Setup (for consent collected another way: your own web form, paper, QR code, kiosk, verbal).

- Use case: Marketing/Promotional, Informational/Non-marketing, or Mixed. Pick what you will really send. Declaring "informational" and then sending promotions is a use-case mismatch.
- Description: who sends, who receives, what's sent, and how people opt in.
- Two sample messages: include the business name, match the use case, include opt-out wording, and contain no merge fields or custom values.
- Opt-in flow: where the number is entered, what the person sees, and confirmation that opting in is optional. If the form isn't public, provide a public screenshot link.
- Opt-in confirmation message: business name, message frequency, "Msg & data rates may apply", HELP and STOP instructions.
- Privacy Policy and Terms URLs, both publicly accessible.
- Run Review Application (the AI compliance check) and fix anything flagged. Passing it doesn't guarantee carrier approval.
Example sample message

Reply C to confirm or R to reschedule. Reply STOP to opt out.Example opt-in confirmation
Summit Plumbing: You're subscribed to appointment and service texts.
Up to 4 msgs/month. Msg & data rates may apply. Reply HELP for help, STOP to opt out.Rejections and how to fix them
| Rejection cause | Fix |
|---|---|
| Legal name or EIN mismatch | Copy the name character-for-character from the IRS letter. |
| Website not live, or doesn't match the brand | Publish the site with the same business name and contact details. |
| Privacy Policy or Terms missing or not public | Add both pages and link them in the footer. |
| Chat widget on a page with another SMS opt-in form | The widget must be the only SMS consent form on that page. |
| DBA inconsistency | Make the website, policies and checkbox text match. If you use a DBA, add "We are doing DBA as [name]" to the use case. |
| Sample messages missing sender name or opt-out, or containing merge fields | Rewrite them as plain example messages like the ones above. |
| Mixed use case with a pre-checked consent box | Two separate consent checkboxes, neither pre-selected. |
Open the rejected campaign and choose View required fixes to see the reason. Some fields lock after submission, which can mean creating a new campaign; eligible rejected campaigns can be resubmitted without a second vetting fee.

After approval
- Under Settings > Phone System > Phone Numbers, the sending number should show A2P Verified. If not, link it to the approved campaign.
- Carriers can take several business days to receive the updated registration after approval.
- Toll-free numbers use a separate verification process, and Canada-to-Canada messaging from numbers bought on or after 26 March 2025 also needs registration or verification.
