New York LLC Name Search: Check Availability in All 50 States + Domains Free

Version 1.0 — March 2026

Your New York LLC name must clear the state database and avoid domain conflicts before you pay the $200 filing fee. New York carries 2.4 million+ registered entities, meaning name conflicts are common and early verification is essential. BizNameChecker.com checks all 50 states and your domain in one search — free.

Quick Answer: Search the NY DOS Public Inquiry Portal at apps.dos.ny.gov/publicInquiry for New York LLC name availability. Your name must include "Limited Liability Company," "LLC," or "L.L.C." and cannot conflict with existing registered entities. BizNameChecker.com checks all 50 states and your domain in one search — free.

How to Run a New York LLC Name Search

New York LLC names are registered with the New York Department of State, Division of Corporations, State Records and UCC — the single authoritative source for entity name availability. The official search tool is the NY DOS Public Inquiry Portal. The portal is JavaScript-dependent and frequently returns errors, particularly on first visits or mobile devices.

The fastest verified path to a clean search result:

Go to apps.dos.ny.gov/publicInquiry
Select "Entity Name" as your search type
Enter your proposed LLC name
Review both active and inactive entities for potential conflicts

If the portal is down or returning errors, BizNameChecker.com pulls from the same underlying NY DOS database and returns results instantly without the JavaScript dependency or reload cycles.

Key Takeaways

The NY DOS Public Inquiry Portal at apps.dos.ny.gov/publicInquiry is the only authoritative state-level search tool for New York LLC names.
Both active and inactive entity records must be reviewed; an inactive name can still block your registration if deemed deceptively similar.

NY DOS vs. NYC Doing Business Search: Know the Difference

A search on apps.nyc.gov/dbnyc — the NYC Department of Finance "Doing Business Search" — covers only city-level registrations. It is not a substitute for the state-level NY DOS search, and confusing the two is one of the most common filing mistakes in New York.

Clearing your name through the NYC search does not mean your LLC name is available in New York State. These are two separate databases governed by two separate regulatory systems with different legal effects.

The NY DOS Division of Corporations states directly: "A name search of the Department's records is not a guarantee that a name is available for use." That caution applies with even greater force to city-level databases, which have no bearing on state LLC formation.

The operative rule: State-level clearance through NY DOS is required for LLC formation under New York Limited Liability Company Law. City-level clearance through the NYC Department of Finance is a separate business concern that does not satisfy the state requirement. If you are launching anywhere in New York State outside New York City, the NYC search is entirely irrelevant to your LLC filing.

Key Takeaways

The NYC Doing Business Search covers city-level registrations only and cannot confirm New York State LLC name availability.
Founders who rely on the NYC search and skip the NY DOS search risk filing a name that is already taken at the state level.
State-level clearance through NY DOS is the only legally relevant check for LLC formation purposes.

New York LLC Naming Rules

New York Limited Liability Company Law (LLCL) Section 204 governs what your LLC can and cannot be named. A rejected filing wastes your $200 state filing fee and delays your launch while you refile with a corrected name.

Required elements:

The name must contain "Limited Liability Company," "LLC," or "L.L.C." in full
The abbreviations "Ltd." and "Co." are not accepted as standalone replacements for the required designator

Prohibited or restricted terms:

Words implying government affiliation, including "Federal," "State," and "United States"
Regulated terms requiring additional licensing approval before use: "Bank," "Attorney," "University," "Doctor," and "Insurance," among others
Names identical or deceptively similar to any
