Arizona Business Entity Searches & Naming Your LLC

We’re here to help you find the right business name for your Arizona LLC. From searching for a business entity name with the AZ Corporation Commission to understanding naming rules or creating a “Doing Business As” name to register your entity, you’re in the right place.

Arizona Corporation Commission Search

It’s the Arizona Corporation Commission that administers businesses in AZ, rather than the secretary of state. They’ll help you check whether there’s already another Arizona LLC registered with your desired business name. That means searching the Arizona Corporation Commission website using their business search tool. You can easily look up AZ LLCs and corporations by name and other details.

If the business name is already used, that means it’s not available and you won’t be able to register it. Try searching for a different business name instead.

Business Name Registration Rules for Arizona LLCs

Once you’ve decided on a name for your LLC and checked business name availability, you’ll need to meet Arizona Corporation Commission naming rules. Naming rules do vary from state to state — we’ve got general naming rules below, as well as naming rules specific to LLC businesses formed in AZ.

Standard LLC Naming Rules

These rules typically apply to all LLCs, no matter what state they are formed in. You will need to pay attention to these rules, as they will influence the name you choose for your Arizona LLC.

Specific Business Naming Rules in Arizona

In addition to the general rules listed above, the Arizona Corporation Commission has some specific business naming rules for your LLC. You will need to follow these rules if you want to name your AZ business appropriately:

  • If the LLC name contains any of the following words, prior written approval must be obtained from the Arizona Department of Financial Institutions before registration is allowed: 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.
  • Non-professional LLCs shall contain the words “limited liability company” or “limited company” or the abbreviations “L.L.C.”, “L.C.”, “LLC”, or “LC”. If the existing limited liability company name or the fictitious name adopted for use in Arizona does not contain one of those words or an abbreviation of one of those words, then one of those words or an abbreviation of one of those words must be added to it.
  • Non-professional LLCs shall not contain the words “association”, “corporation”, “incorporated”, or an abbreviation of those words.

Arizona LLC Trade Names/“DBA” Names

You might choose to do business under a different name from your legal LLC name. In Arizona, a “DBA” or “Doing Business As” name is referred to as a “Trade Name.” You might choose to use a different name from your AZ formal LLC name for a variety of reasons.

For example, your LLC might be called Phoenix Property Development Holding Company LLC, and you have a chain called Gila Riverside Apartments. You should file a Trade Name to let the Arizona Corporation Commission know. In Arizona, you can do that online, or you can have Incfile do it on your behalf through our Assumed Business Name service.

Trademarks and Service Marks

You must be careful that your Arizona LLC name does not infringe on the trademark or service mark of another business. The easiest way to make sure your proposed business name does not infringe is to carry out a trademark search through Incfile. If it doesn’t infringe, you can even register the name you want as a trademark yourself.
