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.
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.
