30903: Campaign rejection - Incorrect Sole Prop Brand Registration

Eligible for resubmission. Stated by: GHL 155000007572; LC 155000004749.

What this error means

You submitted a campaign for a Sole Proprietor brand that doesn't qualify as one.

Causes, most likely first

  1. The business has an EIN or other tax ID, making it ineligible for Sole Proprietor registration.
  2. Business located outside the US or Canada.
  3. Brand or profile submission has incomplete, invalid or inconsistent business information.
  4. Invalid registration details, a brand name that isn't the real business name, a disposable email, an invalid address, or a mobile number that can't be used for verification.

Fields Twilio names for this error

Twilio’s page for this error names these submission fields in its description of what failed:

  • brand name
  • email address
  • business address
  • verification mobile number

Sole Proprietor limits

Twilio's A2P 10DLC documentation states two separate caps on a Sole Proprietor brand, and they are often confused with each other:

  • One campaign per brand. Twilio's A2P 10DLC overview lists the Sole Proprietor tier as "One Campaign per Brand".
  • One 10DLC number. Only one +1 10DLC number can be registered to a Sole Proprietor campaign. Additional numbers added to that campaign stay unregistered and keep failing.

Neither cap is a queue and neither clears with time. If the business has an EIN, it belongs in Standard or Low-Volume Standard registration instead, which changes both limits.

Sending while registration is still in progress

Twilio documents a stopgap for traffic that cannot wait for registration to complete: use a sender type that is not part of A2P 10DLC. Its documentation names a toll-free number, a short code, or Twilio Verify for verification use cases. This is a way to keep messages moving during registration, not a way around registration.

How to fix it

If your numbers are managed by a platform

If your numbers sit inside a reseller platform, for example LeadConnector numbers inside GoHighLevel, you do not have access to the Twilio Console, and the interface shows the rejection without the code. Ask that platform's support team for the Twilio rejection error code, in writing, before you change anything. You can also read it yourself from your browser, which is faster: see how to get the code.

The substance of the fix is yours to make: the business details, the website, and the opt-in flow described in the Twilio path all belong to you, not to the platform. Make those changes first, confirm they are live, then ask support to resubmit. A resubmission filed before the underlying facts change will fail again on the same reason.

If you own the Twilio account

Confirm eligibility before resubmitting: if the business has a tax ID, register it as Low-Volume Standard or Standard instead. Correct the business details, real business name or DBA, valid email, valid US/Canada address, valid US/Canada mobile for verification (not a CPaaS number). If the campaign failed because of brand or profile data, delete the failed campaign, correct the brand/profile, resubmit the brand, then register a new campaign. If you previously registered Sole Prop and now have an EIN, create a separate Customer Profile, brand and campaign.

Timing and resubmission

Brand-level fault: delete campaign → fix profile → resubmit brand → new campaign. That's a full re-registration cycle, not an edit.

Twilio publishes an indicative review timeline for campaigns: Sole Proprietor campaigns are typically approved or rejected within hours to days, and Standard campaigns go through several layers of vetting and can take up to several weeks. Twilio also states that the vetting fee is assessed only once per campaign, so editing and resubmitting the same campaign does not incur a new fee, while deleting and recreating it does.
