Why A2P 10DLC campaigns get rejected, and how to fix them

A2P 10DLC campaigns are rejected when the registration does not match what a reviewer can see: an opt-in flow that is not visible or not documented, a website or privacy policy that says nothing about text messaging, a vague campaign description, sample messages that do not match the use case, or brand details that do not match the business record. Fix the evidence, not the wording of the form.

The common reasons and the fix

ReasonWhat the reviewer seesFix
Opt-in cannot be verifiedNo page or form showing how a person agrees to textsPublish the form with an unticked consent box, the disclosure text, message frequency, rates notice and STOP and HELP instructions
Privacy policy or terms lack SMS languageA policy that never mentions text messagingAdd a section on messaging and a clear statement that mobile information is not shared with third parties for marketing
Brand details do not matchLegal name, address or tax ID differ from the website and the registryMake the website, the registration and the business record say the same thing
Use case does not match the messagesPromotions sent under a customer-care use caseRegister the use case you actually send, or split into separate campaigns
Vague campaign description'Marketing messages' and nothing elseSay who receives messages, what they say, how often and why the recipient expects them
Sample messages are incompleteNo business name and no opt-out in the samplesWrite samples as you will send them, including the name and STOP language
Public link shortenersA generic shortened URL in a sampleUse a link on your own domain
Website not live or placeholderA parked page or a coming-soon siteLaunch the real site before you register
Restricted contentCategories carriers prohibit or restrictCheck the carrier and registry content rules for your industry before registering

Before you resubmit

  1. Open your own opt-in page as a stranger would and confirm every required disclosure is visible without scrolling through unrelated text.
  2. Read your privacy policy and terms for the messaging language, not just the existence of the pages.
  3. Compare the legal name, address and tax ID across the registration, the website footer and the state business record.
  4. Rewrite the campaign description and samples so a reviewer who knows nothing about you understands the program.
  5. Resubmit once with every fix made, rather than one fix at a time.

One business, one registration

Each business needs its own brand and campaign registered under its own legal identity. Reusing another business's registration, even a related one, is a common cause of rejection and a compliance risk for both.

What we do

We build registered, compliant texting engines for businesses, including the registration, the consent flow and the policy language, on the client's own numbers. See the texting engines build.

Questions people ask.

Why was my A2P 10DLC campaign rejected?

Most often because the opt-in is not visible or documented, the privacy policy and terms omit SMS language, the brand details do not match, or the campaign description and sample messages are vague or mismatched.

Can I fix a rejected campaign and resubmit?

Yes. Fix every issue in the rejection reason first, then resubmit once, so you do not cycle through repeated rejections.

Does a small business need A2P 10DLC registration?

If you send application-to-person texts over standard 10-digit local numbers in the United States, carriers expect the brand and campaign to be registered.
