How to Set Up a DBA in Arizona

Step 1: Start With an Arizona DBA Name Search

If you haven't already, head over to the Arizona Secretary of State's website to make sure your trade name isn't taken by another registered Arizona business. Your name can be similar to other business names, but it’s still a good practice to create a unique name.

TIP: Our business name generator tool is a great resource for entrepreneurs who are still working to create the perfect business name or website address.

In Arizona, your company’s trade name cannot include the following words without approval from the state's Department of Financial Institutions:

  • Bank, Banker, Banking, Banc, Banco, Banque, Credit Union, Deposit, Savings Association, Building Association, Savings and Loan Association, Building and Loan Association, Savings Bank, Thrift, Trust, or Trust Company.

For more information regarding Arizona trade name requirements, check the Arizona Trade Name and Trademark Handbook.

Next, a quick search on the U.S. Trademark Electronic Search System will tell you whether someone else has already trademarked your name.

Now would be the perfect time to make sure there’s a web domain available for your DBA as well.

Is my Arizona DBA protected from being used in other places?

There are some state-level laws that prevent DBAs that are too similar to existing ones from being used, but your name is not protected outside Arizona. It is possible to create a federal trademark for a DBA, which would offer stronger protection across state lines.

How many DBAs can I have?

You can have as many DBAs as you can afford to create and are able to keep track of. However, more isn’t necessarily better. Each one will come with additional incremental expense and paperwork, so you will want to make sure you have a good reason for each one you have.

Can a DBA get an EIN or Tax ID?

DBAs aren’t required to have a separate EIN because DBAs aren’t a business entity. The business entity that the DBA is under would have an EIN if an EIN is required.

To learn more about EINs and when you would need one for your business, read What is an EIN from our friends at TRUiC.

Can a DBA become an LLC?

Your DBA is just a name. A DBA is often confused with a sole proprietorship. If you mean “can my sole proprietorship become an LLC?” then the answer is “Yes. Absolutely.”

To learn how to form an LLC, visit our Form an LLC state guides.

Can a DBA have "Inc." in the name?

A DBA can only have "Inc." in the name if the business entity the DBA is attached to is a corporation.

How do I set up a DBA for a rental property?

It’s always best to consult an attorney. Usually, the best option is to Form an LLC to protect your personal assets in the event of an issue with the rental property. Holding the rental property in your name and with a DBA will not afford you any protection.
