# 30701: Brand Registration Failure: Invalid input parameters

Log Type: APPLICATION

Log Level: ERROR

## Description

Your Brand registration request includes one or more fields that do not pass validation. Review the specific field names and validation messages returned with the error, then correct those inputs before you resubmit the Brand. Common validation failures include length limits, invalid enum values, country-specific address checks, invalid phone number formatting, and invalid email addresses.

### Possible causes

* A text field exceeded the allowed length for that property, such as `friendly_name`, `business_name`, `business_registration_number`, `first_name`, `last_name`, `street`, `city`, `email`, `stock_ticker`, or `website_url`.
* `phone_number` or `mobile_phone_number` was not provided in `E.164` format.
* An address field failed validation. This can happen when `street`, `city`, `region`, `postal_code`, or `iso_country` does not form a valid address for the country you submitted. For U.S. and Canadian addresses, `region` should use the two-letter state or province abbreviation.
* `email` was malformed, used an unknown domain, used a disposable domain, or otherwise failed email validation.
* An enum field used an unsupported value, such as `stock_exchange` or `business_industry`.
* The invalid value is stored in the customer profile or related registration data used to create the Brand, so the Brand submission continues to fail until that underlying data is corrected.

### Possible solutions

* Review the error details for the exact field names that failed validation, then update only those properties and resubmit the Brand registration.
* Keep each submitted value within the allowed length for that field. If you send enum fields such as `stock_exchange` or `business_industry`, use only supported values.
* Format contact phone numbers in `E.164`, for example `+12025550123`.
* Use a well-formatted email address with a valid, non-disposable domain.
* Verify that the business address is complete and valid. Use the correct street, city, matching `postal_code`, a two-letter `region` value where required, and a two-letter `iso_country` code.
* If the invalid data is in the customer profile or trust bundle associated with the Brand, update that underlying record first, then resubmit or update the Brand registration.
