New York Corporation Name Search and Naming Rules

Your corporation's name must be distinguishable from every other business name already on file with the New York Department of State. Start by searching the state's records so you're not building a brand around a name that's already taken.

Where to search

Use the Department of State's business entity search. Search your proposed name and — importantly — close variations of it. A name that merely resembles an existing one may not clear, so look for anything that sounds or reads similarly, not just an exact match.

The search is a screen, not a verdict

This is the single most important thing to understand: the online search is a screening tool, not an official availability determination. The Department of State makes the final call when it reviews your Certificate of Incorporation. A name that looks free in the public search can still be rejected at filing if the state considers it too similar to an existing entity. Treat a clean search as encouraging, not final.

Search broadly

The distinguishability test compares your name against many entity types on record, not just other corporations. Search widely and think about how a reviewer might see your name next to existing ones, including LLCs, limited partnerships, and other registered entities.

"Distinguishable" is a legal standard, and it's stricter than casual intuition. Two names can feel different to you and still be considered too similar by the state.

Differences that usually don't make a name distinguishable

• Punctuation and spacing. Adding a comma, a period, or changing spacing generally won't separate two otherwise-identical names.
• Articles and connectors. Adding or dropping words like "the," "a," or "and" typically isn't enough on its own.
• The entity designator. Swapping "Inc." for "Corp." or "Corporation" doesn't distinguish a name whose distinctive words are identical to an existing entity's.
• Singular vs. plural or number formats. Minor grammatical variations often don't count as distinguishing.

What does distinguish a name

A genuinely different distinctive element — a different core word or a meaningfully different combination — is what separates your name from what's on file. When in doubt, choose a name with a distinctive element rather than one that leans on a common word plus a designator, since the common-word names are the ones most likely to collide.

Why this matters at filing

If the Department of State decides your name isn't distinguishable, it rejects the certificate. That's lost time and, if you'd already started branding, real disruption. Picking a distinctive name up front is the cheapest insurance against a rejection.

Beyond distinguishability, New York imposes content rules on corporate names. A name can be perfectly unique and still be rejected because of what it contains.

Required corporate designator

A New York business corporation's name must include a corporate indicator — "Incorporated," "Corporation," "Limited," or an abbreviation such as "Inc.," "Corp.," or "Ltd." This is what signals to the world that the entity is a corporation with the liability characteristics that implies. A name without a designator won't clear.

Words that require consent or approval

Certain words are restricted because they imply a regulated activity. Using them typically requires approval or consent from the relevant state agency before the Department of State will accept the name. These commonly include words suggesting:

• Banking or finance — "bank," "trust," and similar terms tied to regulated financial activity.
• Insurance.
• Education — words implying a school, college, or university.
• Licensed professions — names implying a professional practice may carry their own rules, sometimes requiring a professional corporation.

Prohibited implications

A corporate name can't falsely imply a governmental connection or suggest a purpose the corporation isn't authorized to pursue. If your desired name brushes up against any of these categories, sort out the approval before you file, or the certificate will stall.

Sometimes you've found the right name but aren't ready to file the Certificate of Incorporation. New York gives you ways to protect and use a name outside the formation itself.

Reserving a corporate name

You can file an Application for Reservation of Name with the Department of State to hold your chosen corporate name for a limited period. Reservation locks the name against others while you finish preparing — it does not create the corporation. It's useful when you need time to line up founders, capital, or documents but want to make sure the name is still there when you file.

Assumed names (DBAs)

If your corporation will operate under a name different from its official legal name, you file a Certificate of Assumed Name with the Department of State. For corporations, this is a state-level filing (unlike sole proprietors and general partnerships, who file assumed names at the county clerk). An assumed name lets one corporation run multiple brand names without forming separate entities.

Name vs. trademark

Clearing a name with the Department of State is not the same as securing trademark rights. State name availability only means no other New York entity is registered under a confusingly similar name — it doesn't protect you against trademark claims. If your brand matters, a trademark search and possibly a registration are separate steps worth taking, ideally with counsel.

When we form your corporation, we check your proposed name against the Department of State's records and flag obvious conflicts before we file — so a foreseeable rejection doesn't cost you time. If you're weighing a name that includes a restricted word or leans heavily on a common term, we'll point out the risk so you can adjust before it becomes a filing problem.

If you want to lock a name in advance of filing, we can handle the name reservation, and if your corporation will operate under a different brand name, we can file the Certificate of Assumed Name. What we can't do is guarantee the Department of State's final judgment on distinguishability — no one can, because that determination is the state's to make at review. What we can do is get you a name that's much more likely to clear and handle the filings around it cleanly.

Beyond the state check

Trademark clearance and brand protection are separate from state name availability, and they're best handled with a trademark attorney. We make sure your name works for the New York filing; protecting it as a brand is a distinct project we'll point you toward when it matters.
