How to Search an LLC in Kentucky?

The fastest way to search for an LLC in Kentucky is through the Kentucky Secretary of State's website. It's free, it's updated regularly, and it takes about two minutes.

1. Kentucky Secretary of State's Website

The online Business Entity search lets you look up LLCs by business name, entity number, executive name, and more. It's the most reliable starting point.

To search for an LLC in Kentucky using the Secretary of State's website Business Entity search, follow these steps:

  • Visit the Kentucky Secretary of State's Business Entity Search page.
  • Choose how you want to conduct your search, either by Business Name, Organization Number, City Name, or Zip Code search.
  • Enter your search criteria and click the search button to retrieve results.
  • Review the search results. Each listing will provide detailed information about the LLC, such as its status, registered agent, principal address, and filing history.

Note: The search is free and updated regularly as new filings are processed — though there can be a short delay between when a filing is submitted and when it shows up online.

Here's a breakdown of what each search option entails:

a. Business Name

This search option allows users to look up a business entity using its legal name or a portion. It is the most common method to find information about a specific company.

To use it enter the full or partial name of the business you're interested in.

The search is not case-sensitive but may be affected by including or excluding terms like "LLC," "Inc.," etc.

It's advisable to start with a broad search term and narrow it down as needed.

This method is ideal for when you know the name of the LLC but need to find out more details about it, such as its status, Kentucky registered agent, or filing history.

b. Organization Number

The Secretary of State assigns every business entity registered in Kentucky a unique Organization Number. This option allows for a direct search using that specific identifier.

To use it input the exact Organization Number assigned to the business.

This will yield the most precise results, directly pulling up the entity's profile without sifting through similar names.

The method is best used when you have direct information about the LLC's registration and want to access its records quickly and accurately.

c. City Name

This search allows users to find business entities based on the city they are registered in. It's useful for identifying businesses within a specific geographic location.

For the City Name option, enter the city's name where the business is located.

This method is helpful for a broader search within a particular area, especially if the business name or organization number is unknown.

It is useful for local market research, understanding the business landscape of a specific city, or finding potential business partners or competitors in a given locality.

d. Zip Codes

Similar to the city name search, this option enables searches based on the zip code where the business is registered. It offers a more granular approach to location-based searching.

This search will list all businesses registered within that postal area, providing a concise view of the entities operating in a specific neighborhood or region.

It is ideal for demographic research, local compliance checks, or when planning to establish a new business and wanting to survey existing entities in the same postal region.

2. Call the State

If you'd rather talk to a real person, you can call the Kentucky Secretary of State's office directly. A representative from the business services division can answer specific questions, help you interpret search results, or work through any issues you're running into.

For business entity search inquiries, call (502) 564-3490.

Before you call, jot down the business names or organization numbers you're asking about. It'll make the conversation faster and more productive.

3. Send an Email

Email works well for non-urgent requests or when you need to submit specific details in writing. It's not the fastest option, but it creates a paper trail — which can be useful.

You can reach the Kentucky Secretary of State's Business Services division at sos@ky.gov.

To use the email:

  • Compose an email detailing your request or question regarding the LLC search.
  • Be as specific as possible, including any relevant business names, organization numbers, or other pertinent details to help the staff effectively address your query.
  • Include your contact information so they can follow up if needed.

4. Other Business Entity Search Alternatives

For a broader search beyond the official state resources, consider these alternatives:

  • Search Engines like Google can help identify if the business name is in use elsewhere.
  • Social Media Platforms such as Facebook, Twitter, and LinkedIn can provide insights into the business's online presence.
  • Trademark Searches to ensure the name isn't trademarked and avoid legal issues.
  • Business Directories and listings for a broader search on the business's operational status.
  • Professional Networking Sites can offer connections and background information related to the business and its executives.

How to Check If A Business Name Is Trademarked in Kentucky?

A card for trademark concept

To check if a business name is trademarked in Kentucky, you'll want to use the United States Patent and Trademark Office (USPTO) website. The Kentucky Secretary of State's office is also worth checking at the state level.

This matters more than most first-time founders realize. In fiscal year 2017 alone, the United States Sentencing Commission reported over 66,000 copyright and trademark infringement cases 1. A name conflict can mean rebranding from scratch — or worse, a lawsuit. Running a trademark check before you file is one of the easiest ways to protect yourself.

Here's how to do it right:

1. Federal Trademark Search

The USPTO keeps a comprehensive database of registered trademarks and pending applications at the federal level. A federal trademark covers all 50 states — so if someone has already registered your name nationally, it doesn't matter that you're operating in Kentucky.

To perform a federal trademark search:

  • Visit the USPTO's official website and use the Trademark Electronic Search System (TESS).
  • You can search for trademarks by name, owner, or serial number.
  • Run multiple searches — including phonetically similar names — to make sure nothing slips through.

If you need help, the USPTO's Trademark Assistance Center is reachable at (800) 786-9199.

2. State's Trademark Search

Kentucky also offers a state-level trademark search through the Secretary of State's website. According to the Kentucky Secretary of State's annual report, over 10,000 trademark searches were run through this tool in the past year — which tells you how much is at stake locally.

State trademarks don't carry the same national weight as federal ones, but they're still binding within Kentucky. If you're building a business that operates primarily in-state, this search is worth doing.

To use the State's trademark search:

  • Access the Kentucky Secretary of State's trademark search page.
  • You can search for trademarks by keyword, owner name, or registration number.
  • This tool helps identify if a business name or logo is already used within the state as a trademark.

3. Alternatives

Federal and state searches are your two main moves, but don't stop there. A couple of additional checks are worth running before you commit to a name.

These include:

  • Domain Name Search: Check if the domain name corresponding to your proposed business name is available.
  • Hire a Professional: Consider hiring a trademark attorney or a professional search firm.

You should search for an LLC in Kentucky to:

  • Ensure the business name is unique and available.
  • Identify if the business name is trademarked.
  • Gather information about competitors.
  • Check the legal standing and compliance of the business.
  • Understand the business's history and background.
  • Evaluate the reputation of the business.
  • Assist in due diligence for potential investments or partnerships.
