Last Updated on

Quick Reference

In Missouri, a business operating under a fictitious name will need to register.  Learn more about what a Fictitious Name is, who needs one and how to register.

What is a Fictitious Name?

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

When a business wants to operate under a name other than their legal name, the state of Missouri, like most states, require the business to register their business name.  The registration requirement was designed to protect consumers from business owners hiding anonymously behind the name of a business.

Who needs to register?

The requirements and need to register for a Fictitious Name vary, depending on the type of business entity.

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 but doesn’t use a business name he doesn’t have to register.  If John decides to name his business John’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.
