30734: Brand Registration Failure: Sole Proprietor brands are not enabled

Sole Proprietor brand registration is not enabled for this account. Sole Proprietor registration is available only for eligible customers in the United States or Canada who do not have a business Tax ID and who use the supported onboarding flow.

• This account is not enabled to create Sole Proprietor brands.
• The business is not eligible for Sole Proprietor registration. Sole Proprietor registration is limited to U.S. or Canadian sole proprietors without an EIN or Canadian Business Number. Businesses with a Tax ID must register as a Standard or Low-Volume Standard Brand instead.
• The wrong onboarding path is being used. Direct customers register Sole Proprietor brands in Console, while ISVs typically register Sole Proprietor brands for customers through the API flow.

• If you are a direct customer, create a Starter Profile and register the Sole Proprietor brand from Console under Messaging > Regulatory Compliance > Onboarding.
• If you are registering brands for customers as an ISV, use the Sole Proprietor API onboarding flow and verify that the registration information is complete before you submit the Brand.
• If the business has an EIN, a Canadian Business Number, or is located outside the United States or Canada, register it as a Standard or Low-Volume Standard Brand instead of a Sole Proprietor Brand.
• If this account should be able to register Sole Proprietor brands, contact Support for enablement help.
