While it’s not required, we would recommend first checking to see if there is a trademark protecting the name you want to use. To research names:
– Go to the United States Patent & Trademark Office at
– When you get to click on Trademarks.
– Click on the Search Trademark Database.
– Next click on Basic Word Mark Search.
– In the Search Term field type in the business name you want to use.

There are a number of listings that will likely come up. If the name you want to use shows up with a live status, this would be a cause for concern because someone has a registered trademark. There may be similar names that incorporate the name you want to use, which could be close enough to keep you from using that name.

If you do a search and your name you want is registered, you may want to consider getting professional help from an attorney or service that specializes in intellectual property and/or trademarks. If you don’t, you may invest a lot of time and money establishing a business name that you may have to abandon.

Once the trademark search is out of the way, the process of registering a business name will vary depending on the type of organization chosen.

For sole proprietorships or partnerships there are two options. One is to operate under the owner’s full first and last name, like John Smith. This type of name does not need to be registered. Most businesses will however want to operate under a trade name like John Smith’s Handyman Service, Mr. Handyman, and so on. The term trade name is sometimes referred to as fictitious business name, doing business as, DBA or assumed name. Applying for this type of name allows your business to legally operate and transact business with a name other than your personal name.

To register a business name for a sole proprietorship or partnership, visit the Arizona Secretary of State’s website and fill out the Trade Name Registration form. The cost is and will need to be renewed every five years.

To register a name for a corporation or LLC, you must have a unique name at the time of filing. To check the availability of names, visit the Arizona Secretary of State’s website.
