Kentucky Business Name Search: How to Check and Reserve a Name

Before you file the paperwork to form your Kentucky LLC or corporation, you need to know two things: is the name available, and does it meet Kentucky's legal requirements? A quick search can save you from discovering months later that your chosen name is already taken, or worse, filing papers only to have the Secretary of State reject them.

This guide walks you through the exact process of conducting a Kentucky business entity search, understanding what makes a name compliant, and reserving your name before someone else does.

What You Need to Get Started

You do not need software, special tools, or an attorney to search for a business name in Kentucky. Here is what you will need:

A web browser (Chrome, Firefox, Safari, or Edge)
An internet connection
5 to 15 minutes
Knowledge of Kentucky's naming rules (covered below)
A list of 2 to 3 name options, in order of preference
A credit card or bank account to pay the $15 reservation fee (optional if you are not reserving)

If you plan to reserve your name, you will also need an email address where you can receive confirmation of your reservation.

Understanding Kentucky's Business Naming Rules

Kentucky has specific rules about how you can name your business. Not every name you like will be legal, and the Secretary of State will reject filings that do not follow these rules. Understand the rules before you search, so you do not waste time on names that will not work.

For Limited Liability Companies (LLCs)

If you are forming an LLC, Kentucky law requires that your company name include one of these identifiers:

The words "limited liability company" (in full)
The words "limited company" (in full)
The abbreviation "LLC"
The abbreviation "LC"
The abbreviation "LTD CO" (if abbreviating "limited company")

Valid examples: "Smith Consulting LLC", "Blue River Limited Liability Company", "Acme Services LC"

Invalid example: "Smith Consulting Co." (does not include a required LLC identifier)

For Corporations

If you are forming a corporation, Kentucky requires that your name include one of these:

"Corporation"
"Incorporated" or "Inc."
"Company" or "Co."

Valid examples: "Tech Innovations Inc.", "Smith Marketing Corporation", "Turner Ventures Co."

The Distinguishability Rule

Your name must be distinguishable from every name already on record with the Kentucky Secretary of State's office. This does not mean it has to be completely unique, it means the Secretary will not approve two names that are so similar that they could confuse customers. For example, "Smith Consulting LLC" and "Smith Consulting Limited Liability Company" would likely be considered the same name and rejected if both were submitted.

Names that differ only in abbreviations, punctuation, articles (a, an, the), or word order will probably be rejected as indistinguishable. If your first choice is unavailable, you will need to choose a substantively different name.

Step 1: Visit the Kentucky Secretary of State Search Portal

Open your web browser and go to the official Kentucky business entity search database:

https://sosbes.sos.ky.gov/BusSearchNProfile/search.aspx

This is the authoritative record of every registered Kentucky business entity, LLC, corporation, limited partnership, and others. Any name in this database is taken. Any name not in this database is potentially available, though you should still confirm with the Secretary of State before relying on it.

You may also search from the main Kentucky Secretary of State business filings page at https://www.sos.ky.gov/bus/business-filings/Pages/default.aspx, which will link you to the search tool.

Step 2: Search Your First Choice

On the search page, you will see a text box labeled "Business Name" or similar. Type your desired business name exactly as you plan to file it. Do not include your LLC or Corporation designator yet, just search the core business name.

For example, if you want "Smith Consulting LLC", search for "Smith Consulting".

Click "Search" or press Enter.

Step 3: Interpret Your Results

The search will return one of two outcomes:

Available (No Results)

If the search returns no results, or states "No matching records found", the name (or a name similar enough to it) is not on file. This is a good sign, your name is likely available.

However, "available in the Secretary of State database" does not automatically mean the name is yours to use. You should still:

Check whether another business is using the name as a trademark (search the U.S. Patent and Trademark Office database at www.uspto.gov)
Do a general web search to see if another company is actively using the name in your industry
Reserve the name with the Kentucky Secretary of State if you want to lock it down for 120 days

Taken (Search Results Appear)

If the search returns one or more results, the name is already registered. The results will show you the entity name, the entity type (LLC, corporation, etc.), and the file number. If your exact name, or a name too similar to it, appears in the results, you cannot use that name. You will need to choose a different name and search again.

Go back to your list of alternatives and repeat this step with your second choice.

Step 4: Check Formatting Compliance

Before you move to reservation, make sure your final name includes the required designator for your entity type. Review the naming rules above and confirm:

If LLC: name ends with "LLC", "Limited Liability Company", "Limited Company", "LC", or "LTD CO"
If Corporation: name ends with "Corporation", "Incorporated", "Inc.", "Company", or "Co."

The Secretary of State will check this automatically when you file, but catching it now saves a rejection and resubmission.

Step 5: Reserve Your Name (Optional but Recommended)

If your search shows the name is available, you can reserve it for 120 days before you file formation documents. This is optional, but strongly recommended if you are not ready to file your LLC or corporation articles immediately.

A name reservation prevents anyone else from filing a business with that name while the reservation is active. It costs $15 and is filed through the Kentucky One Stop Business Portal or via the FastTrack Online Filings system.

How to Reserve

Go to https://onestop.ky.gov/ (the Kentucky One Stop Business Portal)
Look for the option to reserve a business name or file a Certificate of Name Reservation
Enter your desired name and confirm it meets the naming rules for your entity type
Pay the $15 fee online
You will receive an email confirmation with your reservation number and expiration date

The reservation is valid for 120 days from the date of filing. After 120 days, if you have not filed your formation documents, the reservation expires and the name becomes available for others to use. You can file a new reservation if needed, but you cannot extend an existing one.

If you do reserve the name, keep your confirmation email safe. You will need the reservation number when you file your LLC Articles of Organization or corporation Articles of Incorporation.

Tips to Avoid Common Mistakes

Do Not Forget the Designator

The most common mistake is choosing a great business name but forgetting to add "LLC" or "Corporation" to the end. The Secretary of State will reject your filing if the designator is missing. Always include it when you search and file.

Do Not Confuse Unavailability with Trademark Issues

Just because the Kentucky Secretary of State does not have a name on file does not mean you have a right to use it. A federal trademark may exist, or another business may be using the name in a different state. Do a web search and check the USPTO database to be thorough.

Do Not Wait Too Long to File After Reservation

Your 120-day reservation window is finite. If you reserve a name and then decide to wait six months to file your LLC, you will have to reserve it again (and pay another $15). Plan to file your formation documents within the reservation period.

Do Not File Identical Names Under Different Entity Types

The Secretary of State sees "Smith Consulting LLC" and "Smith Consulting Inc." as distinct names. However, using the same core name for both an LLC and a corporation will confuse your customers and your records. Choose one entity type and stick with it.

Do Not Use Restricted Words Without Permission

Certain words, like "bank", "insurance", "real estate", and "university", are restricted by Kentucky law and require state approval or licensing to use. Avoid them unless your business is licensed in that field, or your filing will be rejected. The Secretary of State publishes a list of restricted words on their website.

What to Expect After You Search or Reserve

If You Conducted a Search Only

You now have confirmation that your chosen name is either available or taken. If available, you can proceed to file your formation documents at any time. If taken, you know to choose a different name.

If You Reserved the Name

You will have a 120-day window to file your LLC Articles of Organization or corporation Articles of Incorporation. During this time, no one else can register a business with that name. When you file your formation documents, reference your reservation number to confirm you have the exclusive right to it.

Once your formation document is filed and accepted by the Secretary of State, the reservation expires (your filed entity replaces it). The name is now officially yours.

Processing Time

Online searches are instant. If you file a name reservation online, it is typically processed within one business day, though occasionally it can take up to three business days.

What Happens Next

Once you have confirmed your name is available and reserved it (or decided to move straight to filing), the next step is to prepare and file your formation documents. For an LLC, this is the Articles of Organization. For a corporation, this is the Articles of Incorporation. Both are filed with the Kentucky Secretary of State and have filing fees (currently $40 for an LLC and $50 for a corporation).

Your business name search is complete. You now have the information you need to move forward with confidence.
