Arizona Corporation Name Search — Check Availability and Rules

Your corporate name must be distinguishable from every other business entity already on record with the Arizona Corporation Commission. Before you invest in a name — much less order signage or a domain — you should confirm it's actually available.

Where to search

Use the Corporation Commission's entity search at ecorp.azcc.gov. Search your exact proposed name, then search close variations: singular and plural forms, alternate spellings, and versions with and without filler words. The database includes corporations, LLCs, and other registered entities, so a conflict can come from any entity type, not just other corporations.

Reading the results

If the search returns an active entity with a name identical or confusingly similar to yours, that name is likely taken for your purposes. Don't rely on a name that's "close but different" — the distinguishability standard is stricter than it looks, and the ACC makes the final call when it reviews your Articles. Searching thoroughly up front is far cheaper than a rejected filing and a delay.

Also check beyond the ACC

A name that clears the ACC can still collide with a federal or state trademark or an existing brand. Before committing, it's worth a look at the USPTO trademark database and a general web search. The ACC only tells you the name is available to register as an entity — it doesn't clear you of trademark risk.

Arizona won't approve a corporate name that isn't distinguishable on the record from existing names. The subtle part is what doesn't count as a distinction.

Differences that usually don't make a name distinguishable

• Punctuation, spacing, and capitalization — "SunState," "Sun State," and "Sun-State" read as the same name
• Articles and conjunctions like "the," "a," and "and"
• The entity indicator itself — adding "Inc." doesn't distinguish you from an existing "Corp." of the same core name
• Singular vs. plural or possessive forms of the same word
• Abbreviations vs. the spelled-out word of the same term

Differences that generally do

A genuinely different core word, an added distinctive term, or a materially different name will usually clear. The safest approach is to pick a name with a distinctive element — a coined word, a unique combination, or a specific descriptor — rather than a generic phrase that's likely already taken in some form. When your name is distinctive, availability problems mostly disappear.

Beyond availability, Arizona law imposes content rules on corporate names.

Required corporate indicator

An Arizona corporation's name must include a word or abbreviation that identifies it as a corporation:

• Corporation / Corp.
• Incorporated / Inc.
• Company / Co.
• Limited / Ltd.

This indicator tells the public they're dealing with a corporation. A name without one of these won't be accepted for a corporation.

Restricted and prohibited words

• Words like "bank," "banc," "trust," "deposit," "credit union," and similar financial terms generally require approval from the relevant regulator and can't be used freely.
• Words implying a purpose the corporation isn't authorized to pursue, or falsely suggesting a government affiliation, are not allowed.
• Certain professional and regulated terms may require licensing or agency sign-off before you can use them in a corporate name.

Match the name to your operations

Whatever name you register on the Articles becomes the corporation's legal name. If you plan to operate publicly under a different name, that's a separate trade name (DBA) filing — in Arizona, trade names are registered with the Secretary of State, not the Corporation Commission. Keep the two straight: the ACC handles your entity name; the SOS handles trade names.

If you've found an available name but aren't ready to file the Articles yet, Arizona lets you reserve the name so no one else takes it in the meantime.

How reservation works

File a name reservation with the Corporation Commission for a set period, paying a small state fee. During that window, the name is held for you and can't be registered by another filer. Reservation does not create the corporation — it only parks the name. When you're ready, you file the Articles of Incorporation as usual.

When it's worth it

Reservation makes sense if there's real competition for the name, if you're lining up branding, financing, or partners before filing, or if there'll be a gap between settling on the name and submitting the Articles. If you're ready to file now, skip reservation and just incorporate — the name is locked the moment your Articles are approved.

Clearing the name is the first concrete step toward incorporating, and it flows naturally into the rest of the process.

Once your name is confirmed available and compliant, you can proceed to appoint a statutory agent, prepare your Articles of Incorporation (with the exact cleared name), and file with the Corporation Commission. The name you searched and cleared is the name that goes on the Articles — so lock in the precise spelling and indicator you want, because that becomes your corporation's legal identity on every future filing, tax return, and bank account.

A little discipline here pays off: search thoroughly, choose a distinctive name, confirm it meets the indicator and restricted-word rules, and reserve it only if you need the runway. Get the name right and the rest of the incorporation goes smoothly; get it wrong and you're looking at a rejected filing or a name change down the road.
