# 30757: Brand Registration Failure: Missing Business Registration Number 

Log Type: APPLICATION

Log Level: ERROR

## Description

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.

### Possible causes

* 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.

### Possible solutions

* 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](https://help.twilio.com/articles/4405758341659-A2P-10DLC-Brand-Approval-Best-Practices))
* If the brand already failed, update the associated customer profile and submit the brand again through the Messaging compliance flow.
