Reserving an Arizona LLC name is optional; you can file Articles of Organization without reserving it first. If you are not ready to form the LLC, an approved reservation temporarily holds a name that meets Arizona's requirements [1].

If you already submitted Articles of Organization for that name, do not apply for a reservation; the ACC says it will reject the application while the formation filing is pending. A reservation does not form an LLC or give a foreign LLC authority to do business in Arizona.

Quick Summary

Arizona LLC Name Reservation Steps

Check the name before filing because the Arizona Corporation Commission (ACC) reviews it against state naming rules. Use the name you expect to put on the LLC's Articles of Organization; if you need a refresher, see what an LLC is.

1. Check Arizona LLC name requirements

• The name must include “Limited Liability Company,” “Limited Company,” or one of the permitted abbreviations “LLC,” “L.L.C.,” “LC,” or “L.C.”.
• It cannot contain “association,” “corporation,” or “incorporated,” or an abbreviation of those words.
• The name must be distinguishable in ACC records and Arizona Secretary of State trade-name records from existing entities, reserved names, registered names, and Arizona trade names [2].

Arizona generally disregards entity endings such as “LLC,” as well as differences in spacing, capitalization, and many punctuation marks when comparing names. For example, “Fox Co.” is not distinguishable from “Fox LLC” under the ACC's comparison rules.

Arizona restricts certain financial terms, including “Bank,” “Credit Union,” “Deposit,” and “Trust,” with exceptions for businesses that meet statutory conditions. ACC instructions say prior written approval from the Arizona Department of Insurance and Financial Institutions (DIFI) is required when those restrictions apply; confirm the current rule before filing.

2. Search Arizona business records

Search the Arizona business records through the ACC's Arizona Business Center (ABC). In ABC, choose File, then Name, then Check Name Availability, and search the exact wording plus close variations [3].

Treat search results as a screening step, not a guarantee that the ACC will approve the name. The ACC applies its naming rules, and its search does not resolve trademark or other legal claims.

If the name appears available, you can reserve it or submit formation papers; reservation is optional. Check domain and social-media availability separately because those searches do not reserve an Arizona entity name.

3. Perform a trademark search

An LLC name reservation and a trademark search answer different questions. The ACC checks whether an entity name meets state filing rules, but that review does not settle trademark or common-law rights.

Search the USPTO trademark database for identical and similar marks used with related goods or services. Also check state records and marketplace use; a database search cannot guarantee legal clearance, so ask a trademark attorney about a close conflict before investing in the name [4].

When the business name is a DBA

Arizona's Secretary of State registers trade names, which are similar to DBAs; the ACC does not register or reserve them. State trade-name registration creates a public record but does not grant exclusive rights, and the state accepts applications through its online Trade Name and Trademark system.

4. Submit the name reservation

To reserve the name, submit the ACC's Application to Reserve LLC Name through Arizona Business Center or by paper [5]. Enter the exact proposed name and choose the entity type that will be formed.

The form asks for the applicant's name and address, signature, and confirmation in the “I accept” box. For paper filings, include the ACC cover sheet because the commission requires one with every document.

Mail or deliver a paper application to the ACC Corporations Division at 1300 W. Washington St., Phoenix, AZ 85007. The current fee schedule lists $10 for regular processing and $45 total for expedited processing [6].

Check the ACC's posted processing times and wait for its approval notice before treating the name as reserved. Once approved, the reservation lasts 120 days from the date the ACC received the application.

You cannot renew the reservation, but you may transfer it before it expires; a transfer does not extend the 120-day period [7]. The ACC approval letter states the expiration date.

A reservation does not create an Arizona LLC; file Articles of Organization to form one. A foreign LLC must separately file a Foreign Registration Statement before transacting business in Arizona.

When you are ready to form, follow our Arizona LLC formation guide. The ACC must approve Articles of Organization before the LLC is formed.
