GoHighLevel A2P 10DLC Registration: Registering Client Senders Step by Step

HighLevel's overview article, modified on 4 September 2026, says A2P registration is required for sending SMS or MMS to US recipients from standard 10-digit numbers, and that numbers should be linked to an approved campaign before sending. Toll-free numbers follow a separate verification process and do not use brand and campaign registration.

The registration belongs to the business that sends the messages. Twilio's guide for software vendors, which describes the same registry system, says a brand represents the sender of a messaging use case, such as the customer's company, and that the vendor should enter the customer's details and not its own. For an agency that means one brand per client.

HighLevel's articles describe four stages: brand details, campaign details, a compliance review inside HighLevel, and submission for carrier review. The sections below take them in order.

HighLevel's overview defines the two paths. A standard brand is for a business with an EIN, tax ID, business number or another accepted registration number. A sole proprietor is for an individual or a very small business with one employee and no EIN, tax ID, business number or registered entity. It says a business with a tax ID should register as a standard brand.

The standard path then splits by volume. HighLevel's campaign guide describes a low-volume standard brand as up to 6,000 SMS segments a day and a high-volume standard brand as up to 600,000, both with multiple numbers.

HighLevel's overview lists the requirements. The legal business name and EIN should match official records, and uploading the IRS CP 575 letter can help. The website has to be live and public, identify the business and match the brand. The campaign needs a realistic description and sample messages. Consent details have to be accurate, with a message frequency disclosure, HELP and STOP information, and accessible privacy policy and terms pages.

The name is where many registrations fail. HighLevel's rejection guide says the legal name and EIN must exactly match the CP 575, that the name on a W-2 or W-9 should not be used, and that if the name runs over several lines, all the lines above the address should be entered.

The website has to be the business's own. The guide lists codes for a site that requires a login, a site under construction, a site that is only a form with no business context, and a privacy policy that could not be found.

• Legal name and EIN exactly as on the CP 575 letter, or a 147c letter from the IRS
• A live public website that names the business and describes what it does
• Privacy policy and terms pages that cover text messaging
• A business email address on the client's own domain
• The list of message types the client will send, marked promotional or informational
• The page where the consent form or widget will be installed

HighLevel's campaign guide sets out the steps. First choose low or high volume. Then choose the setup path. Chat Widget Setup is the default and uses an opt-in widget that HighLevel generates. Manual Setup is for consent collected another way, such as an existing form, a paper form, a QR code, a kiosk or verbal consent.

There are three use case options: marketing or promotional, informational or non-marketing, and mixed. Selecting mixed sets the registered use case to low volume mixed automatically.

On the manual path you write the campaign yourself. The guide asks for a use case description covering who sends, who receives, what is sent and how contacts opt in. Sample messages should identify the sender, match the use case and include opt-out wording, with no custom fields or values. The consent details include the opt-in method, a public address for the opt-in form or a hosted image of it, a description of the flow, the opt-in message, and public addresses for the privacy policy and terms.

Before submission HighLevel runs what it calls an AI compliance review. If a check fails, you fix it and run the review again, and you cannot submit until all required checks pass. The guide states that passing does not guarantee carrier approval.

HighLevel's article on the pre-built campaign flow, modified on 11 September 2026, describes the widget. It carries the frequency disclosure and the data-rates notice. For a mixed program it shows two separate consent boxes, one informational and one promotional, and neither is selected by default.

The agency can change the colors and the header text. The disclosures, required fields, consent boxes, STOP and HELP text and frequency notice are locked. Selecting marketing together with financial or loan content prompts a switch to informational, and age-gated or financial content adds a date of birth field that cannot be removed.

Two conditions catch agencies. The widget has to be installed and publicly viewable on the submitted page before the compliance check and the final submission. And the campaign guide says it must be the only SMS consent form on that page, so it should not sit beside a contact, lead capture or appointment form that also collects texting consent.

HighLevel's fees article, modified on 10 November 2026, says the one-time fee covers the brand, the first campaign and a 3 dollar fast-track charge meant to bring approval within three business days. It is 22.50 dollars for sole proprietor and low-volume standard brands and 64 dollars for high-volume standard brands. The article says all fees are passed through from The Campaign Registry, Twilio and the carriers with no HighLevel markup.

Monthly campaign fees in that article are 2 dollars for a sole proprietor campaign, 10 dollars for standard use cases, 1.50 dollars for low volume mixed, 3 dollars for charity and 5 dollars for emergency services. HighLevel's LC Phone pricing guide, modified on 12 October 2026, lists slightly higher ceilings of 2.10 and 10.50 dollars. The two pages do not agree, and the Trust Center shows the price that applies.

The LC Phone guide says charges begin when a campaign is submitted, whatever the review outcome, and that deleting the campaign stops future monthly charges. It also says campaign resubmissions have been free since 1 February 2026, when an earlier 15 dollar resubmission fee was removed. The fast-track charge is described as non-refundable.

HighLevel's guide to rejection reasons, modified on 16 October 2026, says granular codes replaced general ones from 23 March 2026. It groups the correctable codes by area and lists a second set that is not eligible for resubmission, covering restricted content such as cannabis, gambling, payday loan marketing, third-party debt collection and third-party lead generation.

The guide's instructions depend on status. While a campaign is pending, wait, and do not resubmit or create another. When it is rejected and correctable, open the required fixes, correct every reason, review the whole campaign and resubmit. It warns that the use case and the opt-in message may not be editable, in which case a new campaign is needed, and that a second rejection may raise new reasons.

Brand attempts are limited. The guide says that a message reading 'Maximum 3 tries exhausted' means registration attempts failed on mismatched or invalid business details, and that the way forward is to send HighLevel the CP 575 letter through a form so its team can submit the brand.

HighLevel's article on the Agency Trust Center, modified on 27 October 2026, says the console is limited to agencies on its 497 dollar a month plan and to agency owners and agency admins. It sits under Settings, Phone Integration, Trust Center. The sub-account Trust Center remains in place.

It has three tabs. The overview shows counts of sub-accounts that are fully approved, in review and rejected, with the brand and campaign rejection reasons. The brands and campaigns tabs list each registration with filters and an actions menu that offers fix and resubmit where the status allows. A sub-account counts as fully approved only when both its brand and its campaign are approved.

An agency admin can start a registration from there: open the brands tab, choose to start a registration, select the target sub-account, enter the business details and submit. A campaign can be created only for an approved brand.

An approved campaign records how the business says it collects consent. It holds no record of which contacts gave it. That record has to exist somewhere else, for each person.

The gap has shown up in court. TCPAWorld, a law-firm blog, reported in March 2026 on Garvey v. Gaitan, a class action in the District of Nevada against a Las Vegas realtor who sent ringless voicemails to expired listings through GoHighLevel. The blog reported that the class was certified and that the defendant had no documentation of consent. We read this through our research notes and did not open the court's order.

CTIA's guidelines list the records a sender should keep for each opt-in, including the timestamp, the wording and action used, and the phone number.
