Arizona Business Entity Search

Check your name against Arizona law before you file. The state's search tells you whether a name exists. It does not tell you whether yours is legal, or whether it is too close to one already on the register. This does both.

What this does not check

  • • Whether the name is already taken. That needs the state’s live register, which we link below.
  • • Trademarks. A name can be free on the state register and still infringe a federal or common law mark.
  • • Domain and social handle availability.
  • • Whether the name is available in any other state you later register in.

Arizona LLC naming rules

A.R.S. § 29-3112 and A.R.S. § 29-3112(B), (D)

Your name must include one of

  • Limited Liability Company
  • Limited Company
  • L.L.C.
  • LLC
  • L.C.
  • LC

Your name must not

  • • "Association", "corporation" or "incorporated", or an abbreviation of any of them
  • • "Bank", "deposit", "credit union", "trust" or "trust company", alone or combined, where they suggest the company is in the banking, credit union or trust business, unless it actually is or is a holding company with a substantial interest in one that is

When is a name too close to one already registered?

This is what catches most filings. Arizona compares your name against what is already on the register, and a difference that looks obvious to you may not count.

These do not make a name different

  • • Words, phrases or abbreviations indicating a type of entity are not taken into account at all: corporation, corp., incorporated, Inc., professional corporation, P.C., professional association, P.A., limited, Ltd., limited partnership, L.P., limited liability partnership, L.L.P., registered limited liability partnership, R.L.L.P., limited liability limited partnership, L.L.L.P., registered limited liability limited partnership, R.L.L.L.P., limited liability company, L.L.C., limited cooperative association, limited cooperative, or L.C.A.

These do

  • • The name must be distinguishable on the records of the Commission or the Secretary of State from every existing entity, every name a person is registered to do business under, every reserved or registered name, and any name registered under A.R.S. § 44-1460

Names Arizona will accept with the other company's consent

  • • The holder of a conflicting name may consent in a record, but Arizona asks for more than consent: that person must also submit an undertaking, in a form the Commission finds satisfactory, to change their own name to something distinguishable

Our comparison cannot judge: Repeated or dropped letters. Texas treats "Texxas Strong" as the same name as "Texas Strong". Words that sound alike. Texas treats "Xpress Auto" as the same as "Express Auto". Words that mean the same thing in another language, where the state translates them. Anything the filing officer decides at their own discretion, which every state reserves.

Searching the official register

  • • Arizona compares against registered trademarks as well as entity names, which most states do not
  • • We have not published a direct link to the Commission’s entity search because their site would not serve us when we checked, and we only publish a link once we have loaded it ourselves

Exceptions worth knowing

  • • A conflicting name may also be used if you deliver a certified copy of a final court judgment establishing your right to the name in Arizona
  • • A foreign series registering to do business in Arizona must include the word "series" in its name
