How to Set Up a DBA in Colorado

by Etch Tabor ; Updated September 26, 2017
In Colorado, DBAs are referred to as trade names.

DBA stands for "doing business as." Nearly all states require that if you are operating a business under a name other than the name of the business owner or business partners, than you must register this name, which is referred to as the DBA. In Colorado, DBAs are known as trade names. Business owners may register their trade names online via the Colorado Secretary of State's Business Division's website. Trade name registration costs $20 per name.

Visit the Colorado Secretary of State's Business Division website. Click on "File a business document" under the "Online Services" section. Then click on "Trade Name" under "Register a." Trade names can only be registered online. If you have any questions regarding the process, you may contact the Secretary of State's Business Division.
