Searching Arizona's business registry changed meaningfully in early 2026 — the legacy eCorp system was fully retired on January 2 and replaced by the new Arizona Business Center portal, and Arizona still requires newspaper publication of a new LLC's formation notice in most counties, a step many other states dropped years ago.
This guide covers exactly how to search for an Arizona business or check LLC name availability in 2026 — the new Arizona Business Center search tool, the distinguishability standard, the newspaper publication requirement (and its Maricopa/Pima County exception), and what a search actually reveals about an existing company.
How to Search for a Business in Arizona
Use the Arizona Corporation Commission's Arizona Business Center (formerly eCorp) to search for an existing business or check whether a new LLC name is available. Search by business name, business id, statutory agent name, principal (member/manager) name. The search is free.
Search directly at arizonabusinesscenter.azcc.gov/businesssearch.
The Arizona Corporation Commission (ACC) fully retired the legacy "eCorp" system on January 2, 2026, replacing it with the Arizona Business Center portal on January 12, 2026 — old eCorp bookmarks and URLs now redirect, so don't be alarmed if a saved link looks unfamiliar. Run your search in Exact Match mode first to check for a direct conflict, then switch to Contains to see the broader landscape of similar names before you commit.
A result shows the entity's Business ID, formation date, status, statutory agent, and — because Arizona requires it in the Articles of Organization — the names and addresses of members or managers depending on how the LLC is managed. The ACC also publishes explicit "Determining Distinguishability" guidance you can reference directly when a result looks borderline.
Checking Name Availability Before You File
Self-check your proposed name using Exact Match mode in the Arizona Business Center before reserving or filing. A clear result is preliminary only — the ACC makes its final distinguishability call when you actually reserve the name or submit your Articles of Organization.
Arizona's Distinguishability Standard
A.R.S. §29-3112 requires entity names to be distinguishable from existing entities and registered trade names on ACC and Secretary of State records. Arizona's separate trade-name statute uses an explicit "same as or deceptively similar" test — a slightly different and arguably stricter standard than the general entity-distinguishability rule, so a trade name search and an entity search can each catch conflicts the other misses.
Reserving a Name in Arizona Before You Form
Name reservation available: For $10 regular; $45 expedited, you can reserve your chosen name for 120 days before filing.
Reservation is optional, not required to form an entity, and runs 120 days without renewal — once it expires, you'd need to reserve again. You can transfer a reservation to another party within the window using a Notice of Transfer form, which is a useful option if a name deal falls through mid-reservation.
Searching for DBAs and Fictitious Names in Arizona
Arizona's DBA — called a "Trade Name" — is registered with the Arizona Secretary of State (a separate agency from the ACC) through the online-only TNTM system, not searchable via the ACC's Business Center. It costs $10 standard or $25 expedited, renews every 5 years for $10, and only the current owner can renew — an ownership change requires a separate Assignment of Trade Name form.
Arizona LLC Naming Requirements
Your new LLC's name must include a designator such as "limited liability company," "limited company," or the abbreviation "L.L.C.," "LLC," "L.C.," or "LC".
Names can't imply government affiliation, and bank/insurance terms or licensed-profession titles (attorney, accountant, and similar) require proof of licensure before the ACC will accept the filing. The trade-name statute's "deceptively similar" standard applies an extra layer of scrutiny to registered trade names specifically.
An Available LLC Name Isn't the Same as a Trademark-Safe Name
Yes — the Arizona Secretary of State's TNTM system also handles trademark and service mark registration, entirely separate from and not cross-checked against USPTO federal trademarks. It provides Arizona-only protection, so it's a supplement to, not a substitute for, federal registration.
The ACC's Business Center and the Secretary of State's TNTM system only check Arizona-registered names and trade names against each other — neither checks federal trademarks. Search the USPTO's Trademark Electronic Search System (TESS) separately before finalizing a name, especially if you plan to operate or market beyond Arizona.
What a Arizona Business Search Reveals
Member or manager names and addresses are required directly in the Articles of Organization and are publicly viewable online through the Arizona Business Center. Because Arizona has no annual report requirement for LLCs, that initial Articles-of-Organization disclosure is essentially the only ongoing public snapshot of ownership — it doesn't get refreshed by a later periodic filing the way it would in most states.
Arizona lists LLC members/owners in the public record, so a search can reveal ownership information.
The Arizona Business Center lets you view the entity's filing history and, for many entities, the underlying document images (Articles of Organization, amendments) directly online — a meaningfully deeper level of access than the bare data fields some smaller states provide.
Getting a Arizona Certificate of Good Standing
You can confirm an LLC's good standing status and request a Certificate of Good Standing through the same Arizona Business Center (formerly eCorp), for $10 regular (7–10 business days); $45 expedited (instant online) (instant online with expedited fee; 7–10 business days for standard processing).
How to Search and Reserve Your Arizona LLC Name
If You Do It Yourself
Step 1 — Search the Arizona Business Center (formerly eCorp) at arizonabusinesscenter.azcc.gov/businesssearch.
Search by business name, business id, statutory agent name, principal (member/manager) name to confirm your desired name isn't already taken.
Step 2 — Apply the state's distinguishability standard, not just an exact-match check.
A.R.S. §29-3112 requires entity names to be distinguishable from existing entities and registered trade names on ACC and Secretary of State records. Arizona's separate trade-name statute uses an explicit "same as or deceptively similar" test — a slightly different and arguably stricter standard than the general entity-distinguishability rule, so a trade name search and an entity search can each catch conflicts the other misses.
Step 3 — Check your name against restricted/regulated words.
Names can't imply government affiliation, and bank/insurance terms or licensed-profession titles (attorney, accountant, and similar) require proof of licensure before the ACC will accept the filing. The trade-name statute's "deceptively similar" standard applies an extra layer of scrutiny to registered trade names specifically.
Step 4 — Confirm your name includes a required LLC designator.
Your name must include a designator such as "limited liability company," "limited company," or the abbreviation "L.L.C.," "LLC," "L.C.," or "LC".
Step 5 — Reserve your name for $10 regular; $45 expedited if you're not ready to file yet.
Reservation is optional, not required to form an entity, and runs 120 days without renewal — once it expires, you'd need to reserve again. You can transfer a reservation to another party within the window using a Notice of Transfer form, which is a useful option if a name deal falls through mid-reservation.
Step 6 — Run a separate USPTO trademark search before you commit.
The ACC's Business Center and the Secretary of State's TNTM system only check Arizona-registered names and trade names against each other — neither checks federal trademarks. Search the USPTO's Trademark Electronic Search System (TESS) separately before finalizing a name, especially if you plan to operate or market beyond Arizona.
Step 7 — File your formation documents promptly once you've confirmed availability.
If you didn't reserve the name, nothing holds it for you — another filer could take it first.
Step 8 — Watch for Arizona-specific search quirks.
Arizona is mid-transition from eCorp to the Arizona Business Center (completed January 2026), so expect some temporary friction and outdated third-party guidance during 2026. The bigger structural quirks: Arizona requires formation-stage newspaper publication for 3 consecutive weeks (waived only for Maricopa/Pima County statutory agents, where the ACC publishes for free), and — unlike almost every other state — Arizona has no LLC annual report requirement at all, so the member/manager disclosure in your Articles of Organization is never refreshed by a later periodic filing.
If LLC Attorney Does It for You
- Submit your desired business name at llcattorney.com along with one or two backup options.
- LLC Attorney runs the Arizona name-availability search, checks it against restricted-word rules, and confirms your designator is correctly formatted before filing.

When Should You Talk to an Attorney About Your Arizona LLC Name?
Talk to an attorney before finalizing your Arizona LLC if you're not sure whether your statutory agent's county qualifies for the free ACC-administered publication or requires you to arrange newspaper publication yourself, if you're navigating the post-migration Arizona Business Center and getting inconsistent guidance from older sources, or if member privacy matters to you given that Arizona has no annual report to refresh disclosure but does require full member/manager listing at formation.
Is Arizona a State Where Name Clearance Complexity Matters More?
Two things make Arizona a genuinely more complex search state right now. First, the ACC fully decommissioned the legacy eCorp system in January 2026 and moved everything to the new Arizona Business Center — expect stale guides, bookmarks, and even some third-party services to still reference the old portal for a while. Second, Arizona requires new LLCs to publish a Notice of Formation in a local newspaper for 3 consecutive weeks within 60 days of formation, except for LLCs whose statutory agent is in Maricopa or Pima County, where the ACC handles publication automatically and for free through its Public Notice Database — a distinction that trips up filers who don't check which county their statutory agent sits in.
What You Actually Get With LLC Attorney's Arizona Name Search
Arizona's publication requirement is easy to miss if you don't know your statutory agent's county qualifies for the free ACC-administered exception. LLC Attorney checks that automatically as part of every Arizona formation order so you're not left arranging newspaper publication you didn't know you needed — or paying for one you didn't need.
- A Arizona name-availability search run for you before you pay any state filing fee.
- Restricted-word and distinguishability screening, so your filing isn't rejected for a naming issue you didn't know about.
- Formation starting at $49, with your confirmed name filed the same day where the state allows it.
- Access to professionally trained Business Success Advisors at no charge, plus flat-fee attorney consultations (no retainer) for trademark-conflict questions.
Arizona's post-migration portal and publication rules have more moving parts than most states — LLC Attorney keeps track of both so your formation clears without a missed step.

Frequently Asked Questions
Yes. The Arizona Business Center's Business Search is free, with no account required — it replaced the legacy eCorp system in January 2026.

Yes, though it's optional. A reservation costs $10 (or $45 expedited) and lasts 120 days without renewal. You can transfer a reservation to another party within that window using a Notice of Transfer form.
