New York LLC Name Rules

Restricted Words

You cannot use "Bank," "Insurance," "University," "College," or "Attorney" in your New York LLC name without special authorization. These words are restricted under N.Y. Ltd. Liab. Co. Law §§ 204 and 1212(b) because they imply regulated services or educational institutions.

New York restricts these five words to protect consumers from confusion and fraud. Using them without proper licensing or authorization violates state law and results in your Articles of Organization being rejected by the Department of State.

The restriction applies to these words in any form or variation. You cannot use derivatives like "Banking," "Banker," "Insure," "Insurer," "Collegiate," or "Legal" to circumvent the restriction. The Department of State will flag your filing if it detects a restricted word without proper authorization documentation.

If your business legitimately operates in banking, insurance, higher education, or legal services, you must obtain written consent from the appropriate regulatory body before filing your LLC:

  • Banking or Insurance: Contact the New York Department of Financial Services
  • University or College: Contact the New York State Education Department
  • Attorney: Contact the New York State Bar Association

Attempting to file without authorization results in rejection and delays your formation timeline. Contact the Department of State at (518) 473-2492 to confirm whether your specific name requires special approval.

Name Distinguishability Standard

Your New York LLC name must be distinguishable from all LLCs, corporations, and limited partnerships already registered with the New York Department of State. You cannot use a name that is identical or confusingly similar to any existing business entity on file, regardless of entity type.

The New York Department of State applies a strict comparison standard. Your proposed LLC name competes for uniqueness against LLCs, corporations, and limited partnerships simultaneously. A corporation named "Smith Consulting Corp." would prevent you from registering "Smith Consulting LLC" because the names are not sufficiently distinguishable.

Minor differences in punctuation, spacing, or articles (like "a" or "the") typically do not create sufficient distinguishability. For example, "Smith LLC," "Smith L.L.C.," and "Smith Limited Liability Company" may be considered identical for distinguishability purposes. However, adding a geographic qualifier or a genuinely different word can establish distinguishability—"Smith Consulting LLC" and "Smith Consulting of New York LLC" would likely be considered distinguishable.

The Department of State evaluates similarity based on how the names appear and sound to the average person. You should conduct a name search before investing time and money in your business plan. A clear search result significantly reduces rejection risk, though it is not a guarantee of approval—the Department of State makes the final determination when you submit your Articles of Organization.

Name Search Process

Before filing your New York LLC, you must search the New York Department of State database to ensure your proposed name is distinguishable from existing LLCs, corporations, and limited partnerships. This search is free and takes minutes to complete online.

You access New York's business name database through the Department of State's public inquiry system at https://apps.dos.ny.gov/publicInquiry/. This official search tool contains all active business entities registered with the state and updates regularly to reflect current filings.

When you search, try multiple variations of your proposed name. Search the name with and without your LLC designator, and search any acronyms or shortened versions you might use. This comprehensive approach helps you identify potential conflicts before you file. You can filter results by entity type (LLC, corporation, limited partnership) to focus on the most relevant comparisons.

If the search shows no conflicting names, you have reasonable confidence that your name will be accepted. However, the Department of State makes the final determination when you submit your Articles of Organization. A clear search result is not a guarantee of approval, but it significantly reduces rejection risk.

You can also contact the Department of State directly for assistance:

  • Phone: (518) 473-2492
  • Address: One Commerce Plaza, 99 Washington Avenue, Albany, NY 12231
  • Website: https://dos.ny.gov/

Name Reservation

You can reserve an available LLC name with the New York Department of State for 60 days by paying a $20.00 fee. This holds your chosen name while you prepare your Articles of Organization, giving you time to complete your formation without losing your preferred business name.

You must reserve your name through the New York Department of State's online filing system at https://filing.dos.ny.gov/. The reservation protects your chosen name for exactly 60 days from the date of approval, after which it becomes available to other applicants if you haven't filed your Articles of Organization.

You can also submit your reservation by mail to:

One Commerce Plaza
99 Washington Avenue
Albany, NY 12231

To reserve a name, you must submit an Application to Reserve a Name (Form DOS 1500) along with the $20.00 fee. You can renew the reservation for an additional 60 days if you need more time, though each renewal requires a separate $20.00 fee.

Your reserved name must still comply with all New York naming requirements: it must include a required designator ("Limited Liability Company," "LLC," or "L.L.C."), avoid restricted words without authorization, and be distinguishable from all existing business entities. Verify availability using the free business search at https://apps.dos.ny.gov/publicInquiry/ before submitting your reservation request.

A name reservation does not give you exclusive rights beyond the 60-day period. Once the reservation expires, another business can register the same name. If you plan to file your Articles of Organization, do so before your reservation expires to lock in your name permanently.

DBA and Trade Name Requirements

If you plan to operate your LLC under a name different from your registered LLC name, you must file a Certificate of Assumed Name (DBA) with the New York Department of State. This is a separate filing requirement in New York—you cannot simply use a different name without formal registration.

For example, if your LLC is registered as "Smith Consulting LLC" but you want to operate as "Smith Business Solutions," you must file a DBA certificate. The DBA filing costs $25.00 and is submitted to the New York Department of State, not to a county clerk.

The DBA certificate must be filed before you begin operating under the assumed name. Operating without a filed DBA can result in penalties and may affect your ability to enforce contracts or sue in court under that name. The filing is straightforward and can be completed online or by mail.

You can file your Certificate of Assumed Name through the Department of State's online filing system at https://filing.dos.ny.gov/ or by mail to:

One Commerce Plaza
99 Washington Avenue
Albany, NY 12231

You can file multiple Certificates of Assumed Name if your LLC operates under several different trade names. Each filing requires a separate $25.00 fee.

Your DBA must still comply with New York's distinguishability standard: it cannot be identical to or indistinguishable from names of LLCs, corporations, and limited partnerships already on file with the Department of State. Verify availability using the free business search at https://apps.dos.ny.gov/publicInquiry/ before filing.

If your DBA includes restricted words—"Bank," "Insurance," "University," "College," or "Attorney"—you may face additional restrictions under N.Y. Ltd. Liab. Co. Law §§ 204 and 1212(b). Confirm eligibility with the Department of State before filing.

You should note that filing a DBA does not protect your assumed name from use by others. The DBA is a registration requirement, not a trademark or exclusive-use protection. If you want exclusive rights to your business name, you should consider registering a trademark with the U.S. Patent and Trademark Office.

Filing Your LLC Name with the Department of State

Once you have selected a distinguishable name, reserved it if desired, and confirmed compliance with all restrictions, you are ready to file your Articles of Organization. Your LLC name appears on this document and becomes your official legal name in New York.

Your LLC name must include one of these designators: "Limited Liability Company," "LLC," or "L.L.C." per N.Y. Ltd. Liab. Co. Law § 204. This designator is mandatory and must appear in your filed name exactly as written in your Articles of Organization. The Department of State will reject your filing if the designator is missing or incorrectly formatted.

Your LLC name must be distinguishable from all LLCs, corporations, and limited partnerships already on file with the Department of State. Run your search before investing time in your business plan using the free database at https://apps.dos.ny.gov/publicInquiry/. Even minor differences in spelling, punctuation, or word order may not satisfy the distinguishability standard, so verify your exact proposed name matches nothing on file.

You cannot use restricted words—"Bank," "Insurance," "University," "College," or "Attorney"—under N.Y. Ltd. Liab. Co. Law §§ 204 and 1212(b). If your business name includes any of these words, you must obtain written consent from the appropriate regulatory authority before filing. Contact the Department of State at (518) 473-2492 to confirm whether your specific name requires special approval.

Submit your Articles of Organization to the New York Department of State, Division of Corporations, State Records and Uniform Commercial Code. You can file online at https://filing.dos.ny.gov/, by mail to One Commerce Plaza, 99 Washington Avenue, Albany, NY 12231, or by phone at (518) 473-2492.

Processing times vary depending on your filing method—online filings are typically processed faster than mail filings. Once approved, your LLC name is officially registered and protected under New York law. You'll receive a file-stamped copy of your Articles of Organization confirming your LLC's legal existence and your exclusive right to operate under that registered name in New York.

Keep a copy of your filed Articles of Organization for your records. This document serves as proof of your LLC's legal existence and your exclusive right to operate under that registered name in New York.

If you conduct business under a name other than your registered LLC name, you must file a Certificate of Assumed Name (DBA) with the Department of State. The filing fee is $25.00. File your DBA through the same online filing system at https://filing.dos.ny.gov/ or by mail to the Albany address above. Your DBA becomes effective when the Department files it.

Frequently Asked Questions

Q: Can I use "LLC" without periods in my LLC name?

A: Yes. The New York Department of State accepts three forms: "Limited Liability Company," "LLC," or "L.L.C." You can use "LLC" without periods. However, you must use one of these three exact forms—no other abbreviations or variations are permitted.

Q: What happens if I use a restricted word without authorization?

A: The Department of State will reject your Articles of Organization. You must obtain written consent from the appropriate regulatory body (Department of Financial Services, State Education Department, or State Bar Association) before filing. Attempting to file without authorization results in rejection and delays your formation timeline.

Q: Do I need to file a DBA if I use my LLC name on all business documents?

A: No. You only need to file a DBA if you operate under a name different from your registered LLC name. If you conduct all business using your official LLC name, a DBA filing is not required.

Q: Can I reserve a name and then change it before filing my Articles of Organization?

A: Yes. Your 60-day reservation protects your chosen name, but you can abandon it and file under a different name instead. However, you would need to search and potentially reserve the new name separately. Each reservation costs $20.00.

Q: How long does it take for the Department of State to approve my LLC name filing?

A: Processing times vary depending on your filing method. Online filings through https://filing.dos.ny.gov/ are typically processed faster than mail filings. Contact the Department of State at (518) 473-2492 for current processing timelines.

Q: Can I trademark my LLC name to prevent others from using it?

A: Filing a DBA or registering your LLC name with New York does not provide trademark protection. If you want exclusive rights to your business name beyond New York, you should consider registering a trademark with the U.S. Patent and Trademark Office.

Q: What if my proposed name appears in the search results but seems different?

A: Contact the Department of State at (518) 473-2492 to discuss whether the names are sufficiently distinguishable. The Department of State makes the final determination based on how the names appear and sound to the average person. Minor differences in punctuation, spacing, or articles may not create sufficient distinguishability.

Q: Can I use a name that is distinguishable in New York but trademarked by another company nationally?

A: Yes, New York's distinguishability requirement only applies to business entities registered with the New York Department of State. However, using a name that conflicts with a federally registered trademark may expose you to trademark infringement claims. Conduct a trademark search at https://www.uspto.gov/ before finalizing your business name.

Q: Do I need to renew my LLC name registration?

A: No. Once your Articles of Organization are filed and approved, your LLC name is registered indefinitely with the New York Department of State. You do not need to renew your name registration. However, you must renew your LLC's business registration annually if required by your county or locality.
