How to search your Arizona LLC name

LLC namesThe first step to forming an LLC in Arizona is to compare your desired Arizona LLC name against the names of existing businesses registered in the state and make sure it’s available for use.

(This is known as being “distinguishable upon the records” with the Arizona Corporation Commission)

Additionally, your Arizona LLC name must follow certain requirements and restrictions in order to comply with Arizona LLC law.

Arizona LLC Name Requirements

Before searching your LLC name in Arizona, there are a few requirements you need to know:

1. Designator

Your Arizona LLC name must include the proper designator (ending) as a part of its official name. As per Arizona statutes, the allowable designators are “LLC” (the most common), “L.L.C.”, “LC”, “L.C.”, “Limited Company”, and “Limited Liability Company”.

2. Not a Corporation

Because an LLC is not a Corporation, your desired name cannot use the word “Corporation”, “Incorporated”, or their abbreviations “Corp” or “Inc”.

3. Distinguishable

Your desired LLC name must be distinguishable. This means it must be different and unique from all other businesses registered in Arizona.

Differences in designators (the identifiers at the end of a business name) and differences in grammar do not create distinguishability.

For example:

  • LLC, L.L.C, Inc., Corp.
  • singular, plural, and possessive
  • A, An, The
  • and, or, &
  • hyphens, slashes, periods, commas
  • three vs. 3

The following examples are NOT distinguishable:

  • Smith Investments, LLC vs. Smith Investments, Inc.
  • Apple Farm, LLC vs. Apple Farms, LLC
  • Print Shop, LLC vs. The Print Shop, LLC
  • Night & Day, LLC vs. Night and Day, LLC
  • Peter Paul & Mary Studios, LLC vs. Peter-Paul-Mary Studios, Inc
  • Three Teachers Consulting, LLC vs. 3 Teachers Consulting, LLC

Searching the Arizona Business Name Database

To make sure your LLC name is distinguishable and available for use, you’ll need to search it in the Arizona Business Entity Database.

1. Visit the AZCC Business Entity Search Page:
Arizona Corporation Commission: Business Entity Search

2. Enter your complete LLC name (including the designator) and click “Name Availability Check”. If a pop-up message appears stating “The Name is Available”, then you’re good to go. If the pop-up message states “The entity name is not available”, you’ll need to come up with a new LLC name or create a variation.

3. To be certain that your Arizona LLC is truly unique in the state, instead of doing a “Name Availability Search”, enter your desired LLC name, but this time leave out the designator and click “Search” instead. This way, you can see the names of existing businesses in the state to make sure that your LLC name is not only unique, but that it stands out (in case there is a very similar business name already in existence):

  • If a “No search results were found” message appears, this confirms your desired Arizona LLC name is unique and distinguishable.
  • If the results show business names that are not too similar to yours, then your desired Arizona LLC name is unique and distinguishable.
  • If your desired LLC name appears in the list exactly as you want it, this confirms your LLC name is not available for use and you’ll need to come up with a new LLC name or a unique variation.
  • If you find an LLC name (or names) that are very similar to your desired LLC name, while the name may be available for use, you may want to consider coming up with an alternative LLC name that is more unique.

Does my LLC need a Trade Name (DBA)?

You don’t need to register a Trade Name (DBA/”Doing Business As”) if your LLC will operate under its true and legal name.

Next Step: Arizona LLC Registered Agent

Once you find an LLC name that is unique and distinguishable, you’re ready to select your LLC’s Registered Agent (aka Statutory Agent). We’ll discuss this in the next lesson: Arizona Statutory Agent.

  1. I am attempting to form a multi member LLC in Arizona with two members. When filing for my EIN, it tells me that because there are only two members, I must file a corporation. Is that true?


    • Hi Gary, that is incorrect. You are likely incorrectly interpreting the message in the EIN Online filing. It states, “Since you are a Multi-Member LLC, we must initially classify you as a Partnership. If you do not wish to accept the default classification of Partnership, you can…” and then it tells you that you can file Form 8832 to have your LLC taxed as a C-Corporation or you can file Form 2553 to have your LLC taxed as an S-Corporation. We also recommend checking out how will my LLC be taxed? Hope that helps!
