Who Needs to Register for a Wyoming Trade Name?

Sole proprietorships and general partnerships are the most common business structures to register for a Trade Name. By default, the name of a sole proprietorship and general partnership is the owner(s) legal name. But, unlike most states, it is optional for a Wyoming business to register for a Trade Name1. For example, if John Smith starts a business repairing computers operating under John Smith, he doesn’t need to register for a Wyoming Trade Name.  If John decides to name his business John’s Computer Repair or even John Smith’s Computer Repair, he will need to register for a Wyoming Trade Name.

Even though name registration is optional in Wyoming for a sole proprietor or partnership, it’s commonly needed, as some vendors and banks will require this registration to provide proof of business ownership.

Corporations and Limited Liability Companies won’t typically register for a Wyoming Trade Name since a unique entity name is created during the entity formation process. However, some will want to register for a Trade Name if they have another business or brand name they want to operate in addition to the legal name of the business. This can allow multiple businesses to operate with the liability protection of a corporation or Limited Liability Company without having to form another entity.

Steps to Register for a Wyoming Trade Name

Step 1: Verify Name Availability

A business may not register a name that is the same or similar to another business in Wyoming.
