Who needs a trade name registration (DBA) in Wyoming?

Every kind of business in Wyoming

The Wyoming table lists this for every kind of business.

Registration is voluntary in Wyoming and gives notice rather than exclusive rights, but banks and landlords ask for it when the business trades under any name other than the LLC’s registered name. The application is notarized and the name must already be in use when it is filed.
