Why did my 10DLC brand registration fail with an EIN or legal name mismatch?

The brand is the first half of 10DLC registration. It tells carriers who is sending. Before you can register a campaign, The Campaign Registry checks your tax ID, legal name, and address against outside records. If they do not line up, the brand is marked unverified and everything else stops.

What does this rejection mean?

It means the registry could not match your business details to a real record. Bandwidth describes these identity statuses:

Twilio shows this as error 30795 (tax ID data mismatch) or 30799 (unable to verify registration details). Twilio says most brand checks finish within a few minutes, but a few take more than seven days.

Why does it happen?

1. The name is not exact. Twilio says abbreviations, missing suffixes like "Inc." or "LLC," and DBAs all cause mismatches.
2. The name came from the wrong document. Twilio says to use the IRS CP 575 letter, not a W-2 or W-9. If the name spans two lines on the letter, include both.
3. The EIN is new. Twilio says new tax IDs can take 30 to 90 days to reach the databases used for checks.
4. An SSN was used. Twilio 30795 lists a personal SSN in place of a business EIN.
5. The wrong business type was chosen. A company with an EIN registered as a sole proprietor fails with Twilio 30915.
6. The DBA was entered as the legal name. Put the legal name in the legal name field and the trade name in the DBA field. Twilio 30918 covers a DBA that does not match the legal name.
7. The address is off. Twilio's brand troubleshooting guide lists a legal name or address that does not match tax records as a common cause.

How do I fix it?

1. Find your IRS CP 575 letter. If you lost it, the IRS can issue a 147C letter that confirms the same record.
2. Copy the legal name character for character, including punctuation and the entity suffix.
3. Enter the EIN with no typos. Do not use an SSN.
4. Use the address on file with the IRS or your state.
5. Put any trade name in the DBA field, not the legal name field.
6. Show the same legal name on your website, usually in the footer and on the About or Contact page. See brand name match.
7. If your EIN is brand new and everything matches, wait a few weeks or ask for a manual review.

Twilio says it offers a manual identity review for urgent cases if you send the full EIN letter. It usually takes 5 to 7 business days, and fees apply.

How do I resubmit?

On Twilio, you can resubmit a brand in the unverified or failed state up to three times for free. After that, contact support. Twilio charges $10 for an appeal-based manual re-vet. Twilio also warns that brand resubmissions carry charges from its registration partners, so check before you try again. Other providers price this differently.

Only move on to the campaign once the brand shows Verified or Vetted Verified. See the rejection triage for the campaign stage.

My brand is verified, but my vetting score is low. Is that a rejection?

No. A low score still lets you register campaigns. It lowers how much you can send. Bandwidth says Standard vets are automated reviews by Aegis Mobile or WMC Global, and Enhanced vets are manual and take 2 to 3 months. Commio lists brand vetting at $41.50 to $101.50 at the time of writing.

Bandwidth says a re-vet uses your highest score, not your latest one. Twilio says T-Mobile's cap is shared by every brand under the same EIN. For more, see the T-Mobile page, the AT&T page, and brand vetting.

What if I am a sole proprietor?

The sole proprietor path is for businesses with no EIN. Twilio says it is open to US and Canadian businesses without a business tax ID. It comes with firm limits:

• One campaign per brand and one phone number per campaign (Twilio)
• A one-time passcode sent to your mobile, which you must answer within 24 hours (Twilio)
• The same mobile number used no more than three times, and the same email no more than ten times (Twilio)
• 1,000 messages a day to T-Mobile and 15 SMS per minute to AT&T (Telnyx)

Not every provider offers it. Bandwidth says it does not support Sole Proprietor use cases at this time. If you have an EIN, register a Standard or Low-Volume Standard brand instead. See sole proprietor brand.

What error code will I see?

Other providers show the identity status Unverified with their own wording.
