How to Apply to Register a Trade Name in Arizona

By Terry Masters

Trade names, also known as "doing business as" (DBAs) or assumed business names, enable your company to operate in Arizona using a name that is not its legal name. There are a number of reasons why you may want to use a trade name rather than the legal name of your business. If you're organized as a sole proprietor, a trade name allows you to build a brand around a name that is not your own name. If you're organized as an independent entity, a trade name enables you to operate your business in states where your company's official name is too close to a name used by another entity.

Name Availability

Check to see if the trade name you want to use is available in Arizona. Search the "Registered Name Information Search" database, which is accessible from the Arizona Department of State website, for the same or similar names. Arizona law requires every business to use a name that is unique and easily distinguishable from other business names that are currently in use.

Trade Name Application

Download a Trade Name Registration Application form from the Arizona Department of State website. A link to the form can be found in the business filings section under "Trade Names and Trademarks."

Fill out the Trade Name Registration Application form. The form requires the name and address of the person or entity registering the name, the date the name was first used, and the notarized signature of an authorized party.

Official Registration

File the completed Trade Name Registration Application form with the Arizona Department of State. Include a copy of an identification card, such as a driver's license, for the person who signed the form and the applicable filing fee. The state officially checks the availability of the trade name you want to use. If the name is available, the state will register the name to you. The name will appear in the state registered name database.
