A2P 10DLC registration checklist: check your brand and campaign before you submit

Twilio says most Standard and Low-Volume Standard brands fail on a mismatch with tax records, so have the IRS letter open while you go through these.

• The legal name is copied from the IRS CP 575 letter, or the 147C that replaces it, every line of it, not from a W-9.

  Twilio's business information page warns that W-2 and W-9 forms may differ from the name registered with the EIN. In GoHighLevel, uploading the CP 575 fills in the name, EIN and address for you. In the guide

• The EIN was issued more than a few weeks ago.

  Twilio says a new EIN can take 30 to 90 days to reach the databases reviewers check, and HighLevel says one under 15 days old may be rejected. If it cannot wait, Twilio Support runs a manual appeal with the EIN letter: usually 5 to 7 business days and $10. In the guide

• The address is a street address that matches the IRS letter, not a P.O. box.

  HighLevel's brand article rules out P.O. boxes, and Twilio rejects details that do not match the tax records. In the guide

• The support email is on the business's own domain, or it is a free address that is published on your website.

  Rejected as 30971. Twilio accepts a free address only when that exact address appears on your site or social profiles; in GoHighLevel a Standard brand should switch to an address at your domain. In the guide

• The person named works at the business, or the agency registering for you holds a letter of authorization, and the support email is not the agency's.

  An agency's email is 30881; a contact who cannot be verified as authorized is 30972. In the guide

• No old agency or platform still holds a brand under this EIN that you no longer text through.

  Twilio's overview allows five Standard or Low-Volume Standard brands per tax ID before campaigns risk 30898. Ask the old agency to remove theirs. In the guide

• The business has no EIN or other tax ID, and no LLC, Inc. or Corp. in its name.

  Sole proprietor registration is only for businesses without a tax ID. An entity name can trigger 30915, and a sole proprietor brand that turns out to have an EIN gets 30903; register a Standard brand instead. In the guide

• The owner's own mobile phone can answer a verification code within 24 hours, and that number backs no more than three sole proprietor brands.

  Both limits are on Twilio's sole proprietor page. HighLevel adds that the number must be a real mobile, not VoIP or a LeadConnector number. In the guide

• The contact email is a free address such as Gmail.

  HighLevel's brand article requires a free email for a sole proprietor brand, the opposite of the rule for Standard brands. In the guide

• The campaign uses the owner's registered name, not a trade name.

  Twilio's 30914 example rejects "MJ's Pet Grooming" on a brand registered as "Maria Johnson." In the guide

• One campaign and one phone number cover everything you plan to text.

  A sole proprietor brand gets one campaign and about 3,000 message segments a day (Twilio's overview), and an extra number on the campaign is blocked with 30034. In the guide

Twilio screenshots and checks the website. Open it on a phone, signed out, before you tick these.

• The address you submit is the main business website, not a landing page or a form on its own.

  A standalone form or landing page is 30920. HighLevel says a form on a subdomain can pass if it looks like the same brand and shows how people find it. In the guide

• It shows the business name, what you do, how to reach you and that you text customers. Any DBA appears in the header or footer.

  Missing business details are 30919; a DBA that does not match the legal name on file is 30918, fixed by adding the DBA to the brand. In the guide

• It opens without a login, and any sign-up page behind a login has screenshots on a public address.

  Reviewers who hit a login return 30921. In the guide

• It is finished and live: not parked, under construction or redirecting to another brand's site.

  HighLevel's rejections article lists 30907, 30891 and 30922 for a site that does not match, does not load or is not built yet. In the guide

• Every link in the registration starts with https.

  An http link is 30964. In the guide

Twilio's API has required both addresses since June 30, 2026, whatever you send, appointment reminders included.

• A public privacy policy says mobile numbers and opt-in data are never shared with third parties or affiliates for marketing.

  Sharing for partner marketing is 30932. HighLevel asks for a clause word for word; the guide prints it under a compliant submission. In the guide

• The policy says how often you text and includes "Message and data rates may apply."

  Both are on Twilio's registration checklist. In the guide

• Terms of service are published on your own domain, with no login.

  Without them, new campaigns are rejected; through the API the codes are 30933 and 30934. In the guide

• There is one privacy policy, it says nothing about buying or selling leads, and both pages are linked under every form.

  Two policies that conflict are 30908. The lead wording and the footer links are HighLevel's rules. In the guide

This is a plain reading of carrier and platform rules, not legal advice; confirm with counsel.

Twilio ties two of these codes, 30924 and 30925, to TCPA and CTIA requirements, so they are the ones worth reading twice.

• The texting box starts unchecked.

  A pre-selected box is 30925. In the guide

• It is a box of its own, separate from agreeing to the terms and privacy policy.

  A form where the terms box is the only box is also 30925. In the guide

• Someone can book, buy or send the form without ticking it.

  Consent required for service is 30923, and HighLevel's best practices article adds that a collected number is not consent on its own. In the guide

• Beside the box, not in a linked page: the kind of texts, how often, "Message and data rates may apply" and how to opt out.

  All four are required at the box by 30924. In the guide

• Promotions have their own box, apart from service texts, and nobody gives marketing consent only out loud.

  One control covering both, or verbal consent for marketing, is 30913. In the guide

• People can say no: no single button grants every permission at once.

  An opt-in with no way to decline is 30931; HighLevel's fix is an unchecked box or a skip option. In the guide

• The message flow describes every way people opt in (website, keyword, paper form, QR code, out loud), with a public screenshot for paper or logged-in sign-ups that shows your company's name.

  Describing only some paths is 30917; evidence showing a different company is 30927. In the guide

This is a plain reading of carrier and platform rules, not legal advice; confirm with counsel.

These fields have to tell one story. A reviewer reads the description, then checks that the samples and the opt-in match it.

• The use case matches what the business really sends, and Mixed was not picked because you were unsure.

  HighLevel's use case article warns against Mixed by default; lead generation chosen for texts to existing customers, or the reverse, is 30916. In the guide

• The description says who sends, who receives and why, in 40 to 4,096 characters, and names your business, not the software.

  A description that names the platform instead of your business is 30886. In the guide

• Each field has its own wording; no block of text is pasted into every field.

  Duplicate text across fields is 30911. In the guide

• Two to five samples name the business, put changing details in [square brackets] and include "Reply STOP to opt out."

  The guide's compliant submission has two samples written out for a service business, ready to edit. In the guide

• At least one sample is a promotional text.

  When the consent covers promotions, make one sample a promotion so the samples match the campaign. In the guide

• No bit.ly-style shortened links appear in the samples or in the texts themselves.

  Public shorteners are 30892 in samples and 30963 in the campaign. In the guide

• Any sample in Spanish or another language has the English translation beside it.

  Registration must be in English: 30910. In the guide

• If a sample carries a phone number, the embedded phone number box under message contents is ticked.

  HighLevel lists the mismatch as 30889. In the guide

The replies are set when the campaign is created. On Twilio, changing them later means a new campaign and a new vetting fee.

• The opt-out reply confirms the request, says no more texts will come and names the business.

  Rejected as 30887. In the guide

• The HELP reply names the business and gives a phone number or email.

  Rejected as 30890. In the guide

• The first text a new contact gets says "Reply STOP to unsubscribe" or something like it.

  Required by Twilio's Messaging Policy. In the guide
