How to Register an Ohio DBA

Last Updated on

Quick Reference

In Ohio, a business operating under a fictitious name will need to register a DBA.  Learn more about what a DBA is, who needs one and how to register.

What is the difference between a Trade Name and Fictitious Name?

A DBA, also known as “Doing Business As”, also commonly refers to a Trade Name and Fictitious Name in Ohio.  What is somewhat confusing in Ohio is that a business can register either a Trade Name or Fictitious Name. 

A Trade Name is a name that must be distinguishable from the other names that are registered with the Secretary of State.  If the name you want is available, this name can be registered and no other business can register it. 

Before a Trade Name can be registered it will have to be used prior to the date of filing.  Ways to use the name include opening a bank account with the trade name, using the trade name on products, any advertisements using the Trade Name or using the name on business cards or letterhead.

A Fictitious Name is a name registered with the Secretary of State but does not have to be unique. A Fictitious Name provides much less protection because other registered names are not required to be distinguishable.  For example, if “Bob’s Landscaping” is registered as a Fictitious Name, an LLC would be able to register “Bob’s Landscaping, LLC” because the names are not required to be distinguishable.

Who needs to register?

The requirements and need to register vary, depending on the type of business entity. 

Sole proprietorships and general partnerships are the most common entities to register for a DBA. 

The legal name of a sole proprietor or partnership can be the owner’s full first and last name, which can be used without registering.  For example, if John Smith starts a business repairing computers but doesn’t use a business name he doesn’t have to register.  If John decides to name his business John’s Computer Repair then he will need to register.  

Corporations and Limited Liability Companies won’t typically register a Trade or Fictitious Name since a unique entity name is created during the formation process.  Some will file for a DBA if they have another business they want to operate under their corporate/LLC umbrella to keep the liability protection without having to form another entity.

Name Restrictions

DBAs can’t be registered using words that are related to banks, trusts, insurance agencies, cooperatives or legal professional associations unless the business is licensed to operate as such.  

Protecting your business name

While registering your Trade Name will keep someone else from registering the exact same name in Ohio, it does very little from someone else operating a business under that name in other states.  If stopping others from using your business name is important, you can protect it through a trademark.
