Register a Trade Name in Ohio

Registering an Ohio trade name, also known as a DBA, is easy!

Note that there is a difference between a “trade name” and a “fictitious” business name in Ohio (although both use the same registration form).

Trade names must be distinguishable from other business names, while fictitious names don’t have to be. Because of this, trade names offer more protection than fictitious names. This guide will focus on Ohio’s Trade Name Registration.

Ohio trade names must be unique and must also meet Ohio’s business name requirements. 

First, visit the Ohio Secretary of State's Business Name Search website and search for your new DBA name to make sure it isn’t already in use.

Next, review the Ohio naming requirements. In Ohio, trade names should NOT include:

  • Any business entity suffix, such as LLC, Incorporated, Corp, etc., unless the business is actually an LLC, corporation, etc.
  • Profanity or words or phrases that are generally considered a slur against an ethnic group, religion, gender, or heredity.
  • Any of the following words without prior approval from the Superintendent of Financial Institutions: bank, banker, banking, trust, or words of similar meaning in any other language.
  • Words that imply that the business is connected with a government agency of Ohio, another state, or the United States.

We recommend checking if your name is available as a web domain (URL). You might not plan on starting a business website today, but you may want to prevent others from acquiring your URL.

After Filing Your Ohio DBA

If filing a DBA marks the beginning of your business journey, then there are a few more steps that you should take before getting started:

  • Create your Business’s Website - Every business needs a website. Luckily, drag-and-drop builders like GoDaddy and Wix make the job quick and easy. Check out our Best Website Builder article to find the tool that’s best for you.
  • Get your Business Finances in Order - You’ll need to separate your business finances from your personal ones. This is accomplished by opening a business bank account. If your business has long lead times or other cash flow irregularities, you can also look into a business credit card.
  • Protect Your Business - While an LLC will help to protect your personal assets in the case of a lawsuit, your business’s assets also need protection. Having the right business insurance will ensure that you’re covered if the worst happens. Most businesses start with general liability insurance as their base coverage.


You can have as many DBAs as you can afford to create and are able to keep track of. Each one comes with additional incremental expenses and paperwork, meaning more is not necessarily better.

DBAs aren’t required to have a separate EIN because DBAs aren’t business entities. The business entity that the DBA is under would have an EIN if an EIN is required.

To learn more about EINs and when you need one for your business, read our What is an EIN guide.

No. An LLC is a business entity, while a DBA is just a name for a business.

Sole proprietorships are often confused with DBAs, but they are not the same: a sole proprietorship is a business entity, therefore it can choose to become an LLC.

To learn how to form an LLC, visit our Form an LLC state guides.

A DBA can only have Inc. in the name if the business entity the DBA is attached to is a corporation.

Holding a rental property in your name and with a DBA will not afford you any protection. The best option is to form an LLC to protect your personal assets in the event of an issue with the rental property. In any case, it is always best to consult an attorney.

Getting a DBA is often a better choice than changing your business’s legal name. If you want to rebrand your company or focus on another line of business, filing for a DBA is a simpler process than filing for a legal name change.

Some state-level laws prevent DBAs that are too similar to existing ones from being used, but this varies from state to state. It is possible to trademark a DBA, which would offer stronger protection across state lines.
