Choosing a business name for your business is exciting, but it can also be a little intimidating.
You need a catchy name that accurately represents your new business, suits your niche, and engages your target audience’s emotions.
And once you’ve chosen the perfect business name, before you register an LLC in New York with that name you must ensure it’s available in New York State (which means conducting a business entity search) and compliant with state regulations.
Here’s the deal: You come up with the business name, and we’ll tell you how to do the rest.
Why Do You Need to Do a Business Entity Search?
A business entity search is when you look for information about a company or organization registered as a legal entity.
You can run a business entity search for several reasons. In our case, it’s to see if your chosen business name is available in New York State.
New York Naming Guidelines
The name you choose for your New York LLC must comply with state guidelines; otherwise, the New York State Department will refuse your application.
New York naming requirements:
- Distinctive: Your business name must be unlike any LLCs, limited partnerships, or corporations on the Department of State’s file. You can confirm this by running a business entity search on the New York Department of State’s Corporation & Business Entity Database.
- Specific inclusions: Your LLC name must contain the words “Limited Liability Company” or the approved abbreviations “L.L.C” or “LLC.”
- Prohibited words/phrases: You cannot include certain words or phrases that indicate a government department, financial or medical institution, or use offensive terms.
Conducting a Business Name Search in New York – Step-by-Step Guide With Tips
Government websites can be confusing (and intimidating). Here are some tips for avoiding mistakes when using the New York Department of State’s business name registration tool.
- All letters are considered uppercase during the name search, so you don’t have to use upper and lower case.
- For best results, search using single names (like a single keyword on Google search).
- Do not add or remove unnecessary spaces; enter your business name as you spell it.
- When searching for a business name, select all entity types.
Now, we’ll look at the tool itself and the different sections.
Search options
Begin by logging into the New York Department of State Business Name Database.
Here you will see the below page:

Next, select the appropriate filters:
- Search by: Entity name/ DOS ID (Department of State Number)/ Assumed name/ Assumed name ID (select entity name).

If your chosen business name appears, click on it to see if it’s active and for further information, which brings you to the below page:

If a business entity is already registered, you must choose a different name and search again.
Fictitious name/DBA/assumed name
A fictitious name (Doing Business As) is a name you can use other than your LLC state-registered name. Or with sole proprietorships, your private name.
To confirm an available DBA, use the same New York Department of State Business Name Database and select “Assumed name.”
You register a DBA by filing a Certificate of Assumed Name with the New York Department of State.
The fees and mailing address are:
- DBA Fee: $25
- County fees: Besides the New York Department of State filing fee, every county where the LLC does business charges an additional county filing fee.
- Mailing address: New York Department of State, Division of Corporations, One Commerce Plaza, 99 Washington Avenue, Albany, NY 12231.

New York Paper publication fees:
New York State also requires new LLCs to publish notification of their registration in a New York paper, which can cost up to $200. Once published, you must provide proof of publication to the state, which costs another $50.
Estimated total cost of registering a New York business name:
- LLC filing fee: $200
- Publication: $100 – $300
- Proof of publication fee: $50
What Can You Do Once You Have an Available Name?
Once you’ve confirmed that your chosen business name is available, you can register it.
However, suppose you need more time to form your LLC. In that case, you can reserve a business name, which allows you to research the domain’s availability and register it as a trademark.
Here’s how you do all 3:
Consider name reservation
You can reserve an available business name for 60 days by filing an Application for Reservation of Name.
How to reserve a business name in New York:
- Confirm the name’s availability on the New York Corporation & Business Entity Database.
- Apply for Reservation of Name under Section 205 of the Limited Liability Company Law.
- Pay the $20 Application for Reservation of Name filing fee.
You can pay by cash, check, MasterCard, Visa, money order, or American Express.
To pay using a credit or debit card, complete the Credit/Debit Card Authorization Form and send it to the Division of Corporations with your service request.
Consider trademarking your name
A trademark protects your LLC’s intellectual property, stopping others from using what you trademark, such as your chosen business name and brand designs, like a logo or slogan.
In our case, we want to trademark your LLC business name, which means first, you must ensure it’s available as a trademark by checking the US Patent and Trademark Office (USPTO) database search tool.
Once you confirm the name’s availability, register or reserve it with the New York Corporation & Business Entity Database because your LLC should come before your trademark.
Finally, apply for a trademark using the US Patent and Trademark Office (USPTO) online application process.
Consider domain registration
You use your LLC name for all legal and branding purposes (unless you use a DBA) and a domain name for your brand’s online digital address.
Ideally, the two should be the same.
To confirm your business name is available as a domain, you must:
- Search availability on a domain registration site, like GoDaddy.
- Run a trademark check with the USPTO.
- Check the domain isn’t registered under a different Top-Level Domain (TLD).
- Confirm the domain is available on all social media platforms using a search tool.
Conclusion
Your next step is to navigate the New York Department of State Business Name Database to ensure the business name you want to use is available.
If it is, consider registering it as a trademark and get the domain.
If it isn’t available, don’t worry because there are many ways to come up with a business name.
Remember, don’t rush choosing your business name because if you start and run your business right, you’ll use it long into the future.
