New York LP Name Search and Naming Rules

New York keeps a searchable database of registered business entities, and it's your first stop for checking whether a proposed LP name is available. Use the Department of State's business entity search to look up your proposed name and its close variants.

How to search effectively

• Search your exact proposed name first.
• Then search variations — drop the "L.P.", change word order, try singular and plural forms, swap synonyms.
• Look for names that are similar in sound or appearance, not just identical. New York's standard is "distinguishable," which is stricter than "not identical."

Treat the result as a screen, not a verdict

This is the important caveat: the public database is a preliminary check, not an authoritative availability ruling. The Department of State makes the final call when it reviews your Certificate of Limited Partnership. A name that looks clear in the search can still be rejected as too similar to an existing name when a state examiner reviews it. So use the search to weed out obvious conflicts and narrow your options — but don't treat a clean search as a guarantee. If a name is critical to your plans, having a backup or two ready saves time if the state disagrees.

New York's Partnership Law imposes specific rules on what a limited partnership can be called. Getting these right before you file avoids a rejected Certificate.

The required designator

Your name must contain the words "Limited Partnership" or the abbreviation "L.P." This is what tells the public — and anyone doing a deal with you — that they're dealing with a limited partnership rather than a general partnership or another entity type. A name without the designator will be rejected.

The distinguishability standard

Your name must be distinguishable on the record from the names of other entities already registered in New York — LPs, LLCs, corporations, and other filed entities alike. Names that differ only by:

• punctuation or spacing,
• filler words like "the," "and," or "a,"
• singular vs. plural of the same word,
• or an entity designator swap (LLC vs. L.P.)

may not be treated as distinguishable. The name has to stand on its own.

Restricted and prohibited words

Certain words are off-limits or require approval from another agency before New York will accept them. These typically include words implying you're a bank, trust company, or insurer, words suggesting a government affiliation, and other regulated terms. If your desired name leans on any of these, expect to either drop them or obtain the required consent first.

If you've cleared a name but aren't ready to file the Certificate — maybe you're still forming the general-partner entity, drafting the agreement, or lining up capital — New York lets you reserve the name so someone else can't take it in the meantime.

How reservation works

You file an Application for Reservation of Name with the Department of State and pay a small state fee. This holds the name for a set period, giving you a window to complete the rest of your formation without racing to file first. Reservation doesn't create the LP — it only parks the name.

When reservation is worth it

• You have a specific name central to your branding and can't risk losing it.
• Your formation is weeks away because of financing, entity setup, or legal drafting.
• You're coordinating a launch and want the name secured before you announce.

For many filers, reservation is unnecessary — if you're ready to file soon, you can simply submit the Certificate and secure the name that way. But when timing is uncertain and the name matters, reservation is cheap insurance.

Sometimes the name you want isn't available as your legal name, or you want to operate under a different brand than your LP's formal name. New York handles this through assumed names.

Certificate of Assumed Name

If your LP will do business under a name other than its legal name, you file a Certificate of Assumed Name (a "DBA") with the Department of State. For LPs and other registered entities, this is a state-level filing — different from sole proprietors and general partnerships, which register assumed names at the county clerk. Your LP can hold several assumed names for different lines of business or brands.

When your legal name is taken

If the exact name you want is unavailable, you have options:

• Adjust the name to make it distinguishable — a distinctive word or a different construction often clears the conflict.
• File under an available legal name and operate a brand through an assumed name.
• For foreign LPs qualifying in New York whose home-state name is taken here, adopting a fictitious name for New York use is standard, and that name is stated in the Application for Authority.

The goal is a legal name that passes the state's review and a brand you're happy to put on the door. Those two don't have to be identical — the assumed-name mechanism is precisely what lets them differ.
