To name your LLC in Arizona, your name must include a required designator, be distinguishable from existing entities on file with the Arizona Corporation Commission (ACC), and avoid restricted words. Once you've confirmed availability through the ACC's entity search, you can lock in the name by filing your Articles of Organization.

Arizona LLC naming requirements

Every Arizona LLC name must follow a set of rules the ACC enforces when it reviews your Articles of Organization. The designator requirement is the one that trips people up most often — it's easy to forget.

• Your name must include a required designator: "Limited Liability Company," "L.L.C.," or "LLC" — any of the 3 forms are acceptable
• The name must be distinguishable from all other domestic and foreign LLCs, corporations, limited partnerships, and limited liability partnerships already on file with the ACC — the ACC excludes designators like "LLC" or "Inc." when making this comparison
• The name cannot imply a connection with or endorsement by a government agency
• Certain words — things like "bank," "trust," "insurance," and "university" — require special approval from Arizona regulatory agencies before you can use them

The ACC reviews distinguishability when you submit your Articles of Organization. If your proposed name is too close to an existing entity, the ACC will reject the filing and you'll need to resubmit with a different name.

How to search LLC name availability in Arizona

Search the ACC's free entity database before you commit to a name. The search is available at azcc.gov and lets you check whether your proposed name is already taken or too similar to an existing entity.

Run a few variations of your name — with and without the LLC designator, with different word orders, and with common abbreviations. The ACC compares names after stripping designators, so "Sunrise Holdings LLC" and "Sunrise Holdings Inc." would be considered the same for distinguishability purposes.

A clear result in the ACC database doesn't mean the name is yours yet. It only confirms no registered entity is using it. You still need to file your Articles of Organization to make it official.

How to reserve an Arizona LLC name

If you've found an available name but aren't ready to file your Articles of Organization yet, the ACC lets you reserve it. A name reservation holds the name for a set period so no other entity can register it while you're getting ready.

File a name reservation application with the ACC to hold your chosen name. This is a separate filing from your Articles of Organization and carries its own fee. Check the ACC's current fee schedule for the exact amount.

Arizona trade names and DBAs

Your LLC can do business under a name that's different from its legal name. In Arizona, this is called a trade name — sometimes referred to as a DBA ("doing business as"). You'd use a trade name if, for example, your legal entity is "Smith Ventures LLC" but you want to market under "Desert Bloom Bakery."

A few things to know about Arizona trade names: registering one does not give you exclusive rights to the name and does not provide trademark protection. It only registers the name for use. Arizona law also prohibits registering trade names that are deceptive, immoral, or infringe on existing trademarks. Some Arizona counties may require additional publication or recording for fictitious name use, so check with your county as well.

Trademarks and your Arizona LLC name

Registering your LLC name with the ACC — or filing a trade name — does not protect you from trademark infringement claims. State registration and federal trademark protection are two separate things, and it's worth understanding the difference before you finalize your name.

Before settling on a name, search the USPTO's federal trademark database to check whether another business has already registered it or filed a pending application. If someone holds a federal trademark on a name and you use it, you can end up on the hook for infringement — even if the ACC approved your LLC name without issue.

If you want nationwide protection for your LLC name or logo, federal trademark registration with the USPTO is the path. A trademark attorney can help you figure out whether your name is registrable and whether any existing marks create risk.

How to register your Arizona LLC name

Your LLC name is registered when the ACC approves your Articles of Organization. There's no separate name registration step — the name becomes official as part of the formation filing itself.

Here's the order of steps: search the ACC entity database to confirm your name is available, check the USPTO trademark database to rule out federal conflicts, reserve the name if you need more time, then file your Articles of Organization with the ACC. Online filing costs $50; paper filing costs $85.

If you want to change your LLC name after formation, you'll need to file Articles of Amendment with the ACC. That's a separate filing with its own fee.
