30757: Brand Registration Failure: Missing Business Registration Number

This error means the brand registration request did not include a business registration number, so Twilio cannot complete brand registration until you add the missing value.

• The brand registration request is missing the business registration number.
• The business registration number was not added to the customer profile or registration data used to create the brand.

• Add the business registration number to the brand registration data, then resubmit the brand.
• Make sure the registration details match the legal business information you use for A2P 10DLC onboarding. (help.twilio.com)
• If the brand already failed, update the associated customer profile and submit the brand again through the Messaging compliance flow.
