Find out what business type is right for you

If you’re planning to form an Ohio LLC or corporation (which is sometimes referred to as “registering your business”), you’ll need to file Articles of Organization to form the LLC or Articles of Incorporation to form the corporation.

However, before you file that document with the Ohio Secretary of State you need to choose a name for your Ohio LLC or corporation. The name that’s on your LLC or corporation’s Articles is its “legal name”. And before filing, it's a good idea to check whether the legal business name you want is available in Ohio.

Why check LLC or corporation name availability?

Choosing a business name is an important decision. Your business name is often the first impression you make on prospects, customers, investors, partners, and employees.

If you choose a business name only to discover that it’s already in use, it can be quite frustrating.

How to conduct an Ohio business name availability search

As with other states, Ohio has rules on what you can name your LLC or corporation. The Ohio Revised Code requires that your business name be “distinguishable upon the records in the office of the Secretary of State” from any previously registered legal name of a corporation, LLC, limited partnership, limited liability partnership, reserved name, or trade name.

What does not make a name distinguishable, for example:

  • The use of punctuation, contractions or abbreviations won’t make your name unique: For example, “Lucky’s Bar” is not distinguishable from “Lucky Bar.”
  • Word variations: Changing the tense or number of a word does not create a distinction. For instance, “Village Bakery” is not distinguishable from “Village Bakeries.”

What makes a name distinguishable, for example:

  • Adding letters: For example, “A Landscaping LLC” is distinguishable from “AA Landscaping LLC.”
  • Different spelling or phonetic variations: “Quickie Laundromat” is distinguishable from “Kwikee Laundromat” or “Kwik-E-Laundromat.”

Note: Ohio allows you to register a trade name or a fictitious name for your business. Trade names and fictitious names are both names your LLC or corporation uses other than its legal name. The main difference between a trade name and a fictitious name is in how Ohio protects them. A trade name must be different from other names already registered in the state. Therefore, if you register a trade name no other business can register the name.

Fictitious names, in contrast, do not need to be different from already registered names. Therefore, a fictitious name provides no protection because multiple entities can register the same fictitious name.

When you’re choosing the name for your Ohio business you should also keep in mind trademark issues. Trademarks are words or symbols used to identify and distinguish a business’ products or services. If you choose a business name that is too similar to a name a competitor has trademark rights to, this can lead to claims of "trademark infringement" or "unfair competition." If someone sues you, you may have to change your business name and pay damages. The legal name you choose does not have to be distinguishable from trademarks. Therefore, the fact that the Ohio Secretary of State will let you form an LLC or corporation using that legal name doesn’t necessarily mean there are no potential trademark problems.

To avoid these costly mistakes and keep your business launch on schedule, it's important to check name availability early on.

How to find if a business name is taken

There's no one place to check for conflicting business names for your Ohio LLC or corporation. Use different search methods to make sure you cover all bases.

1. Check the internet

Research a name you are considering using on a search engine. This will help determine if anyone else is using a similar name for similar products or services.

In addition, check if the website domain name you want is available. Just type the name into the search bar and hit enter. You can also use the ICANN WHOIS Lookup tool for this. ICANN manages all domain names.

2. Search the Ohio Secretary of State’s business entity database

Use the Ohio Secretary of State’s Business Search to research available legal business names. You can also search for Ohio trade names (DBAs) in the same place, as they are also registered with the Secretary of State.

The system offers several search methods:

  • Exact name search, for precise matches.
  • Wildcard search (using the % symbol) for broader results, especially useful when checking name availability or when the full business name is uncertain.

For example, if you want to find businesses that include “Cincinnati” and any variation of “CONTRACT” (such as “CONTRACTOR,” “CONTRACTORS,” or “CONTRACTING”), enter: “CINCINNATI CONTRACT%”.

To ensure accurate results, follow the system’s formatting guidelines. Remove all special characters before searching, including double quotes ("), apostrophes ('), commas (,), pound signs (#), parentheses, underscores (_), plus signs (+), forward slashes (/), and periods (.). Remove any hyphens (-) and concatenate (world-wide becomes worldwide).

When you see consecutive single letters followed by a space or punctuation, treat them as one word. For example, "C.R.S CONTRACTORS" should be searched as "CRS CONTRACTORS".

3. Perform a trademark search

Trademark conflicts may occur if you choose a business name that is already a legally protected trademark of another party. To prevent this, check for registered trademarks through the United States Patent and Trademark Office (USPTO).

The USPTO has a free online trademark database where you can look for exact matches and similar names that might confuse customers.

You can also check if a trademark has been registered in Ohio (if a trademark is used in Ohio but not used in interstate commerce, it can’t be registered on the federal level but can be registered in Ohio). Trademark searches can be done on the Secretary of State’s website.

When searching for trademarks, check for common misspellings and variations of your name. Even if your name isn’t identical to someone else’s trademark, a similar name could still lead to challenges based on potential confusion.

4. Check social media handles

Check whether your preferred handle is available on major platforms, including Instagram, Facebook, TikTok, LinkedIn, X, and Bluesky. Also, consider business listing sites (like Yelp) to prevent any mix-ups with other businesses.

Tips on selecting a business name for your Ohio LLC or corporation

Before choosing a business name, make sure it follows Ohio’s naming requirements.

  • Include the right words: The name of your LLC or corporation must include words or abbreviations that identify the type of entity you are forming. For example, an LLC name must include “Limited Liability Company“, “LLC”, “L.L.C”, “Limited”, “LTD.”, or “Ltd”. A corporation’s name must include “Company”, “co.”, “Corporation”, “corp.”, “Incorporated”, or “Inc.”. Some words need approval before a business name can be registered. For instance, if you want to use the words "bank," "banker," "banking," or "trust" (or similar words in any language), you must get approval from the superintendent of financial institutions. This is required even if the business does not provide banking or trust services.
  • Conduct a trademark search and check business name availability: This ensures your chosen name is not already taken, either as a legal name, trade name, or reserved name on the records of the Ohio Secretary of State, or that the name you want would infringe on someone’s trademark rights.
  • Reserve your business name with the state: Reserving a name secures your rights to it and prevents another entity from forming or reserving an LLC or corporation using the same name before you’ve had a chance to file your Articles of Organization or Articles of Incorporation. In Ohio, a business name reservation lasts for 180 days.
