Arizona business name search
In Arizona, LLC and corporation names are handled by the Arizona Corporation Commission, not the Secretary of State. Search the Arizona Business Center's Business Search with Starts With, Contains or Exact Match, then apply the ACC's "distinguishable" rules. These are minimal: a different word or spelling is usually enough, but punctuation, spaces and entity endings don't count.
How to check if a name is available in Arizona
- 01
Open the Arizona Business Center search
Go to the ACC's Business Search on arizonabusinesscenter.azcc.gov. You can search by business name, business ID, statutory agent or principal name.
- 02
Use Contains, then Exact Match
Start with Contains on your key words to see near matches, then switch to Exact Match. Don't type LLC or Inc.; the ACC ignores those identifiers when judging availability.
- 03
Strip your name the way the ACC does
Mentally remove spaces, punctuation such as apostrophes, hyphens and colons, articles like "the", and letter case. "Bob's Bikes" and "Bobs Bikes" count as the same name, and so do "One Stop" and "1 Stop".
- 04
Use the official availability check
When you are ready to file, the ACC's own steps direct you to Arizona Business Center > File > Name > Check Name Availability. That gives the formal answer.
- 05
Clear trademarks and your web presence
The ACC says outright that its approval is ministerial. Search federal marks at https://tmsearch.uspto.gov/ and confirm the domain and social handles before you print anything.

Arizona business naming rules
- Names only need to be "distinguishable" from other entity and trade names on file, which is a minimal standard. Any real difference in wording or spelling ("Capitol" vs "Capital") can be enough.
- Entity identifiers like LLC, Inc., Corp., Co. and Ltd. (and foreign-language equivalents) are ignored, so "Fox Co." is not distinguishable from "Fox LLC".
- Spaces, most punctuation and symbols, letter case, articles (a, an, the) and numerals vs number words do not make a name distinguishable.
- Prepositions and conjunctions do count, so "Into the Deep Co." differs from "To the Deep Co."
- A name cannot be made up only of identifiers, and the system truncates full names longer than 120 characters.
Reserving a name
The ACC lets you reserve a business name through the Arizona Business Center before you form your LLC or corporation. Check the current fee on the agency's site.
DBAs and trade names
The Arizona Corporation Commission does not register DBA names. Trade names are filed with the Arizona Secretary of State, and filing one is optional.

Frequently asked questions
Who handles business name searches in Arizona?
The Arizona Corporation Commission handles LLC and corporation names through the Arizona Business Center. Trade names (DBAs) go through the Arizona Secretary of State instead.
Is "Smith's Plumbing LLC" different from "Smiths Plumbing Inc." in Arizona?
No. The ACC drops apostrophes and entity identifiers before comparing names, so those two would be treated as the same name.
Does ACC approval mean I own the name?
No. The ACC describes its review as ministerial. Approval doesn't give you trademark rights, so run a USPTO search as well.
Do I need a DBA in Arizona?
The Secretary of State describes trade name filing as optional. It puts your business name on public record, but it isn't legally required.
General information, not legal advice. Name approval is decided by the Arizona Corporation Commission (Corporations Division); a name showing as available in a search is not a guarantee it will be accepted.
