Arizona LLC Name Search: Check Name Availability Before You File

Quick Answer: To search LLC name availability in Arizona, use the Arizona Business Center at arizonabusinesscenter.azcc.gov — the official portal run by the Arizona Corporation Commission (ACC). A name must be distinguishable on the record from all existing registered entities under Arizona Revised Statutes § 29-3112. Check your domain at the same time, because LLC availability and domain availability are two separate problems.

Arizona has over 774,000 small businesses, according to the SBA Office of Advocacy 2023 Small Business Profile. That means your preferred LLC name has a real chance of already being taken. The search takes two minutes. Skipping it can cost you a filing fee, a rejected application, and a forced rebrand before you launch.

How to Search for an Arizona LLC Name

The Arizona Corporation Commission (ACC) is the only agency that controls LLC registration in Arizona. Start at the Arizona Business Center (arizonabusinesscenter.azcc.gov), the ACC's official online name search portal. Type your proposed name, review the results, and confirm no existing entity is close enough to trigger a conflict under the distinguishable-on-the-record standard.

Step-by-step:

  1. Go to arizonabusinesscenter.azcc.gov
  2. Click "Search" or navigate to the entity name search
  3. Enter your proposed LLC name. Try variations: singular, plural, with and without LLC
  4. Review all returned results for phonetic and visual similarity
  5. If clear, proceed to reserve or file directly through the ACC eFiling Portal

One critical note: the Arizona Secretary of State (AzSOS) handles trade names and DBAs in Arizona, not LLC registrations. Searching azsos.gov will not confirm LLC availability. That confusion is the most common mistake first-time filers make. They search the wrong portal, see no results, and assume they are clear.

Key Takeaways:

  • The Arizona Corporation Commission (ACC) controls LLC name registration, not the Arizona Secretary of State (AzSOS)
  • Always search arizonabusinesscenter.azcc.gov specifically. Azsos.gov returns trade name data, not LLC records
  • Searching the wrong portal produces a false clear result that can lead to a rejected filing and lost fees

Arizona LLC Naming Rules Under A.R.S. § 29-3112

Arizona law requires your LLC name to be distinguishable on the record from every other registered entity in the state. Arizona Revised Statutes § 29-3112 sets the legal standard, and it is stricter than many founders expect.

Swapping "LLC" for "Co." or "Company" does not make a name legally distinct. Changing "The" to "A" does not make a name legally distinct. The ACC evaluates the substantive words in the name, not just the legal designator at the end.

Your Arizona LLC name must also:

  • Include "Limited Liability Company," "LLC," or "L.L.C." as part of the official name
  • Not imply a government affiliation (no "FBI," "Treasury," "State Department," etc.)
  • Not use restricted words like "Bank," "Insurance," or "Trust" without the appropriate regulatory approval
  • Not be deceptively similar to an existing entity. The ACC evaluates phonetic similarity, not just exact matches

According to the Arizona Corporation Commission, the state processes over 80,000 new business entity filings annually. With that volume of registered names, generic business names in common industries face the highest collision risk.

Key Takeaways:

  • Arizona Revised Statutes § 29-3112 requires names to be substantively distinguishable. Minor word swaps do not qualify
  • Restricted words like "Bank" and "Insurance" require regulatory pre-approval before the ACC will accept the name
  • The ACC evaluates phonetic and visual similarity, not only exact character-for-character matches

ACC vs. AzSOS: Which Portal to Use

TaskCorrect Portal
Check LLC name availabilityArizona Business Center (ACC)
Search trade names / DBAsArizona Secretary of State (AzSOS)
Reserve an LLC nameACC eFiling Portal
File Articles of OrganizationACC eFiling Portal
Register a DBA after LLC is formedArizona Secretary of State (AzSOS)

The Arizona Secretary of State (AzSOS) and the Arizona Corporation Commission (ACC) are separate agencies with separate databases. Neither pulls data from the other. Three separate government domains appear in search results for the same query. That is why founders routinely land on the wrong portal first.

The practical rule: if it involves your LLC's legal name, use the ACC. If it involves a trade name or DBA operating under an already-formed LLC, use the Arizona Secretary of State (AzSOS).

Key Takeaways:

  • LLC name searches must go through the Arizona Corporation Commission (ACC), not the Arizona Secretary of State (AzSOS)
  • Using the wrong portal produces a false clear result. Your name may already be taken even if AzSOS shows nothing
  • The ACC and AzSOS maintain entirely separate databases with no shared data between them

How to Reserve an Arizona LLC Name

If your name is available but you are not ready to file, Arizona offers a 120-day name reservation for $10 through the ACC eFiling Portal. Filing a reservation locks your name against new registrations while you finalize your operating agreement, EIN application, or funding structure.

The $10 fee is paid directly through the ACC eFiling Portal. Reservations are not renewable. When 120 days expire, the name returns to open availability. If you need longer protection, your only option is to file the full LLC formation.

According to the Arizona Corporation Commission, name reservations are a formal filing and appear in the public database immediately. That means a competitor searching the same name will see it is already reserved.

The Arizona Commerce Authority (ACA) also publishes name availability guidance at azcommerce.com for entrepreneurs researching business formation in the state. The ACC remains the authoritative source for legal name status.

Key Takeaways:

  • Arizona allows a 120-day LLC name reservation for $10 through the ACC eFiling Portal
  • Reservations appear immediately in the public database, protecting your name from competing filings
  • Reservations are not renewable. After 120 days, the name returns to open availability with no grace period

Arizona LLC Filing: Fees and Processing Times

ItemDetail
Articles of Organization filing fee$50 (standard)
Expedited processing (ACC)Available for additional fee
Name reservation fee$10 for 120 days
Annual report fee$0 (Arizona has no annual report requirement for LLCs)
Standard processing time14–16 business days (standard); 3–5 days (expedited)

Arizona eliminated the annual report requirement for LLCs, making it one of the more maintenance-friendly states for small business owners. According to the SBA Office of Advocacy 2023 Small Business Profile, small businesses employ 1.5 million Arizonans. That is 44.1% of the state's private-sector workforce. The state ranks consistently among the top five nationally for new business formation.

File directly at the ACC eFiling Portal (efiling.azcc.gov). The ACC does not accept paper filings for most LLC transactions.

Key Takeaways:

  • Arizona's LLC filing fee is $50. The state requires no annual report, reducing ongoing compliance costs
  • Expedited processing is available through the ACC eFiling Portal for time-sensitive formations
  • Standard processing runs 14–16 business days. Expedited processing reduces that to 3–5 business days

Check Your Domain at the Same Time

LLC availability and domain availability are completely separate systems. The ACC approves "Mesa Digital Services LLC" for Arizona. GoDaddy shows mesadigitalservices.com has been parked since 2019. You now own an LLC with no matching domain.

This happens constantly. According to the SBA, Arizona ranked fifth nationally for new business formation in recent years. First-time founders search the state database, see a clear result, and file without checking whether the brand actually exists online.

According to Verisign's Domain Name Industry Brief, over 350 million domain names are currently registered globally. The odds of your preferred .com being available drop significantly the more common your business name is.

The right workflow: check both at the same moment, before you file anything.

Competitor tools fall short in specific ways:

  • ZenBusiness and LegalZoom run name availability checks, but both funnel you into paid formation packages before you see domain results
  • The Arizona Business Center (arizonabusinesscenter.azcc.gov) confirms LLC availability only. No domain check
  • GoDaddy checks domains only. No LLC database access
  • State Secretary of State sites are single-state only and do not check domains

Summary: Arizona LLC Name Search Checklist

  • Search the Arizona Business Center (arizonabusinesscenter.azcc.gov). Not AzSOS
  • Confirm your name meets the distinguishable-on-the-record standard under Arizona Revised Statutes § 29-3112
  • Avoid restricted words without regulatory approval (Bank, Insurance, Trust)
  • Include "LLC" or "L.L.C." in the legal name
  • Reserve for $10 through the ACC eFiling Portal if you need 120 days before filing
  • Check your .com, .co, and .io domain at the same time
  • File Articles of Organization at efiling.azcc.gov for $50

Arizona's dual-portal system. Arizona Corporation Commission (ACC) for LLCs, Arizona Secretary of State (AzSOS) for trade names. This creates real confusion for first-time filers. Use the right portal from the start, check your domain before you commit to the name, and file with confidence.

Frequently Asked Questions

How do I find out if my LLC name is available in Arizona?

The Arizona Corporation Commission (ACC) maintains a free online database where you can search for registered business names at azcc.gov. Simply enter your desired LLC name to check if it's already taken or reserved in Arizona. You can also contact the ACC directly by phone or visit their office in Phoenix to conduct a name search in person.

How do I look up an Arizona LLC?

You can search the Arizona Corporation Commission's business entity database online at azcc.gov/divisions/corporations, which is free and accessible 24/7. The search allows you to look up any registered LLC by company name, LLC number, or registered agent name. According to the ACC, there are over 400,000 active business entities registered in Arizona as of 2024, so you should be able to find comprehensive information about most established LLCs.

How can I check if a company name is taken?

Beyond the Arizona state database, you should also search the U.S. Patent and Trademark Office (USPTO) database at uspto.gov to ensure the name isn't trademarked federally, which would prevent you from using it. Additionally, conducting a Google search and checking social media platforms can reveal if the business name is actively used by competitors. For comprehensive protection, consider searching multiple databases including county records and the Secretary of State database in any other states where you plan to operate.

How much does it cost to register a business name in Arizona?

The filing fee to register an LLC in Arizona is $50 if you file online through the ACC's portal, according to current ACC fee schedules. If you file by mail, the fee is $50 as well, though mail processing may take 5-10 business days longer than online filing. Additional costs may apply if you need a registered agent service (typically $100–$300 annually) or choose to hire a business formation service to handle the paperwork for you.

What information do I need to register an LLC name in Arizona?

To register your LLC in Arizona, you'll need to provide your desired business name, principal office address, registered agent information, and details about the LLC members or managers. The ACC requires that your LLC name end with "LLC," "L.L.C.," or "Limited Liability Company," and it cannot contain words restricted by Arizona law such as "bank" or "insurance" without proper licensing.
