How to Register a DBA in Wyoming

Last Updated on

Quick Reference

In Wyoming, a business operating under a fictitious name may want to register a DBA.  Learn more about what a DBA is, who needs one and how to register.

What is a DBA?

A DBA, also known as “Doing Business As”, Trade Name, Assumed Name or Fictitious Name is a name used by a business, that is different from the legal name of the business.   

Who needs to register?

It is optional to register a Trade Name in Wyoming.  Even though it is optional, it is often necessary as many banks won’t open a checking account without one.  Additionally, many vendors or suppliers will request one to prove the existence of the business.  The need to register is organized under Wyoming statutes 40-2-101 – 109.

Sole proprietorships and general partnerships are the most common entities to register for a DBA. 

The legal name of a sole proprietor or partnership can be the owner’s full first and last name, which can be used without registering.  For example, if John Smith starts a business repairing computers operating under John Smith he doesn’t need to register.  If John decides to name his business John’s Computer Repair or even John Smith’s Computer Repair then he will need to register. 

Corporations and Limited Liability Companies won’t typically register a fictitious name since a unique entity name is created during the formation process.  Some will file for a DBA if they have another business they want to operate under their corporate/LLC umbrella to keep the liability protection without having to form another entity.

Name Restrictions

DBAs can’t be registered using words that are related to banking or insurance unless the business is licensed to provide those services.  

Protecting your Business Name

While registering your Trade Name will keep someone else from registering the exact same name in Wyoming, it does very little from someone else operating a business under that name in other states.  If stopping others from using your business name is important, you can protect it through a trademark.
