Before formation paperwork goes to the New York Department of State, the name a business wants deserves a check. If an existing entity already holds the name — or uses one so similar that the two could be confused — the filing may be rejected, and a rejected filing means lost time.
This page is about clearing a name that a new business wants to use. It is a different job from finding a company that already exists: for a specific business, the New York Business Name Search page is the better starting point. The first check is the official Corporation and Business Entity Database, the free public search run by the Department of State’s Division of Corporations, State Records and Uniform Commercial Code. It costs nothing and requires no account. One caveat belongs up front: a database search is a strong first look, but the final decision on a name happens when the filing is reviewed.
Why a Name Check Comes Before the Filing
A company name is more than a label. It is the identity that appears on every filing, contract, invoice, and bank form that follows. A name that collides with an existing entity stops that chain at the first step.
The Department reviews names at filing time. Identical or deceptively similar names may cause a rejected filing. A rejection costs more than pride: the filing fee is spent, the paperwork comes back, and the launch date slides.
What a Clean Check Provides
A clean search hands over no certificate, but it clears the biggest unknown. It shows the field of live entities that carry the name or close variations of it. With that picture in hand, a filer can adjust the wording before any money is spent.
Tip: Search the distinctive core of the name, not the full legal wording. A search on a rare word returns more useful results than a search padded with endings such as “LLC” or “Inc.”
How to Check Whether a Business Name Is Available
The goal is a wide net: every existing entity that could conflict with the name should appear in the results. Here is the process:
- Open the official search. Use the button above to reach the Department of State’s Public Inquiry application.
- Select Entity Name. In the Search By field, choose Entity Name.
- Type the core of the name. Enter the distinctive words without an ending such as “LLC” or “Inc.” — endings vary across entity types and narrow the results.
- Choose Contains. The Contains matching option returns close matches along with exact spellings — exactly what an availability check needs.
- Leave every entity type selected. Do not filter, so the results cover corporations, LLCs, not-for-profit corporations, limited partnerships, and LLPs.
- Click Search the Database and read through the results carefully.
Two Outcomes That Matter
Two outcomes matter. An identical match to an existing entity marks the name as taken. Several deceptively similar names mean a crowded field, and a filing under that name risks rejection.
Reading the Search Results
A results page is more than a yes-or-no signal. Each row represents an entity on file with the Department, and each entity carries a full record with type, dates, and status details. Reading a few of those records turns a long list into a clear picture.
What Each Result Row Points To
A result ties to a complete record in the same database. Opening the record shows the entity type, the organization date, the status, and the name in use today. That context matters: an older record with a layered name history reads differently from a young entity carrying the exact name.
When to Widen the Search
A narrow search that returns nothing deserves a second pass before anyone celebrates. Swap Contains for Begins With, drop the ending, or split the name into its distinctive parts. A name with three words can collide under any one of them, so the careful filer tests each part on its own.
Identical and Deceptively Similar Names
The database search works in both directions. An identical match to an existing entity is an obvious conflict. A deceptively similar name — one that differs by a word or a small spelling change but could still be confused with an existing entity — can trigger the same rejection.
Small Differences That Still Count
Small differences rarely settle the question. A comma, a plural, or a shortened word does little to separate two names in the eyes of a reviewer. The variants below show up again and again:
- A singular turned plural, or the reverse
- A hyphen, comma, or period added or removed
- A shortened ending, such as “Incorporated” against “Inc.”
- A common word added or dropped, such as “Group” or “New York”
- A number spelled out in one name and shortened in the other
Keep the limits of the search in mind. Searching the database is the first check, not the final word: the Department reviews each filing on its own terms, and the final decision on a name happens at filing review. When the search leaves room for doubt, the written-request service described below is the next step.
New York Naming Rules to Know Before Filing
New York asks for more than an unused name. A filing needs a name the state can accept on its own terms — one with enough distinct content, the right designator for the entity type, and no words that trigger extra review.
- Distinctive words. A name needs content that separates it from other entities, not a string of generic terms.
- Entity designators. Most entity types must show their structure in the name, such as an LLC ending or a corporate ending. The Department’s filing instructions list the accepted designators for each type.
- Words with restrictions. Certain words draw extra scrutiny for some entity types. The Department’s FAQ and filing instructions flag them, so a quick read of the official pages prevents surprises.
These rules work alongside the database check. A name can be free of live conflicts and still fail on wording, so both angles deserve attention before the filing fee is paid.
Availability Checks by Entity Type
The same database serves every entity type, and the search itself stays the same. What changes is the name being tested: each type carries its legal name in its own formation paperwork.
| Entity type | On file with the Department? | Name being tested |
|---|---|---|
| Business corporation (domestic or foreign) | Yes | The corporate name in the formation filing |
| Limited liability company (LLC) | Yes | The LLC name in the formation filing |
| Not-for-profit corporation | Yes | The corporate name in the formation filing |
| Limited partnership | Yes | The partnership name in the formation filing |
| Limited liability partnership (LLP) | Yes | The partnership name in the formation filing |
| Sole proprietorship or general partnership | No | A DBA filed with a county clerk instead |
Sole proprietorships and general partnerships never enter this database. A name check for those businesses starts with the county clerk that keeps DBA filings.
The DOS Written-Request Name Search
The Department of State offers a name search beyond the database. Its call center can search up to five names per call — phone (518) 473-2492, Monday through Friday, 8:45 AM to 4:30 PM ET. For details on the service and how to submit names, the Division of Corporations is the right contact.
Database Search vs Call-Center Search
This service adds a second layer of confidence. The call center searches the submitted names against the Department’s records, which helps when a database search returns a crowded field. Written requests go to the Division of Corporations at the address below.
| Aspect | Database search | Call-center name search |
|---|---|---|
| Cost | Free, no account | Contact the Division for current details |
| Names covered | Any wording the filer enters | Up to five names per call |
| Output | A live list of entities on file | A search run on the names submitted |
| Best for | A fast first pass with wide matching | A crowded field or a near-final name |
Assumed Names and DBAs
A name check covers more than the legal name. A company that plans to trade under a second name files that name separately, and the second name needs its own clearance.
Corporations, LLCs, and similar entities file a Certificate of Assumed Name with the Department of State. Sole proprietorships and general partnerships file DBAs with county clerks. Either way, the same rule applies: check the trading name before the filing fee is paid.
The New York DBA / Assumed Name Search page walks through the search side, and the Department’s assumed name certificate page lists the filing details for corporations.
Common Mistakes to Avoid
Most availability problems trace back to a handful of habits. These are the big ones:
- Searching the full legal name with its ending. Endings such as “LLC” or “Inc.” narrow the results and hide rivals that share the core.
- Filtering by entity type on the first pass. A conflict can live in any entity type, so the first search should stay wide.
- Stopping at one search. A single wording rarely covers every variant; run two or three versions of the name.
- Treating the search as a guarantee. The Department makes the final call at filing review.
- Ignoring prior names. Records keep earlier names, and those names can still appear in results.
- Skipping the trading name. A clean legal name does not clear a planned assumed name or DBA.
Tip: Run the search twice — once on the distinctive core and once on the full name with its ending. The two passes catch different rivals.
A Checklist Before the Filing Fee
A short routine keeps the name check honest. Run it in this order:
- Search the core. Contains matching, no entity-type filter.
- Search the full name. Exact wording, with the designator included.
- Test close variants. Plurals, hyphens, and shortened endings.
- Check the trading name. An assumed name or DBA needs its own pass.
- Read the nearest records. Type, dates, and status show how close each rival sits.
- Decide before paying. A doubt that remains at this stage is cheaper than a rejection after the fee.
After a Clean Check
A clean check clears the path to the formation filing. The name goes into the formation paperwork, the filing fee is paid, and the Department reviews the submission. The final word on the name arrives with that review.
The New York LLC Publication Requirement
New York adds one more step for LLCs formed in New York: a notice published in two newspapers for six consecutive weeks within 120 days of formation. The name check comes first, and the publication requirement follows formation.
The publication step leaves the name itself untouched. It runs on a clock of its own, so filers who clear the name check early have more room to handle both tasks calmly. Business corporations carry a different follow-up: biennial statements filed with the Department.

Frequently Asked Questions
These answers sort out the questions that come up most often before a formation filing. Each one reflects how the Department of State handles names at review.
Is a database search a guarantee that a name is available?
No. Searching the Corporation and Business Entity Database is the first check. The final decision happens when the filing is reviewed by the Department of State, and identical or deceptively similar names may cause a rejected filing.
How is this different from a business name search?
Name availability looks forward — checking a name before a filing. A business name search looks up entities that already exist. Both use the same official database; the difference is the goal.
What about assumed names and DBAs?
A company that plans to trade under a second name files that name separately. Corporations, LLCs, and similar entities file a Certificate of Assumed Name with the Department of State, and sole proprietorships and general partnerships file DBAs with county clerks. The New York DBA / Assumed Name Search page covers the details.
What counts as a deceptively similar name?
A name that differs from an existing one by a small change — a plural, a hyphen, a shortened ending — but could still be confused with it. These near matches are common, and the Department treats them as potential conflicts at filing review.
Should the entity ending be included in the search?
The better approach is to type the distinctive core of the name and leave endings such as “LLC” or “Inc.” out. Endings vary across entity types, and including one narrows the results too soon.
