Ohio Secretary of State Business Search & Naming Your LLC

Whether you’re searching for the right Ohio business name or registering your LLC with the OH Secretary of State, we can help. We’ve got all the information you need on an Ohio business entity search, LLC naming rules, fictitious names and registering your business.

Ohio Business Entity and Name Search

You should start naming your business by completing an Ohio business entity search with the Secretary of State. They have a helpful tool on their website that lets you search the register of OH LLCs and corporations to see if someone already has your desired business name.

If the business name is already used by an LLC or Corporation in Ohio, that means it’s not available and you won’t be able to register it. Try searching for a different business name instead.

Ohio Secretary of State Rules for Naming Your LLC

Once you’ve decided on a name for your LLC and checked business name availability, you’ll need to meet Ohio Secretary of State naming rules. These do vary from state to state — we’ve got general naming rules below.

General Business Name Availability Rules

These rules typically apply to all LLCs, no matter what state they are formed in. You will need to pay attention to these rules, as they will influence the name you register your business under for your Ohio LLC.

Specific LLC Naming Rules for Ohio

In addition to the general rules listed above, the Ohio Secretary of State has some specific business naming rules for your LLC. You will need to follow these rules if you want to name your OH business appropriately:

If a name contains profanity or words or phrases that are generally considered a slur against an ethnic group, religion, gender, or heredity, it is considered unacceptable.

Ohio Trade Names

You might choose to do business under a different name from your legal LLC name. You might choose to use a different name from your OH formal LLC name for a variety of reasons.

For example, your LLC might be called Ohio Vacation Rentals Holding Company LLC, and you have a chain called “Riverside Rentals.” You should complete an Ohio Trade Name Registration Form to let the Ohio Secretary of State know. In Ohio, you do that through a Name Registration form, or you can have Incfile do it on your behalf through our Assumed Business Name service.
