Ohio LLC naming rules
Naming your Ohio LLC comes down to 3 core requirements: your name must include a required entity identifier like "LLC" or "limited liability company," it must be distinguishable from every other business already on file with the Ohio Secretary of State, and it can't use restricted words without approval. Get those right and you're ready to search and register.
Ohio LLC naming rules
Ohio Revised Code section 1706.07 sets out the naming rules for LLCs formed in the state. Every Ohio LLC name must include one of the following entity identifiers: "limited liability company," "LLC," "L.L.C.," "limited," "ltd.," or "ltd". Without one of these, the Ohio Secretary of State will reject your filing.
Your name also needs to be distinguishable from every other business entity already registered in Ohio. Ohio doesn't treat minor differences — swapping a comma, adding "the," or changing a word from singular to plural — as enough to make a name unique. If the Secretary of State's records already have a name that looks or sounds like yours, your filing can be rejected.
Names that imply a government affiliation or include restricted words like "bank," "attorney," or "university" require additional approval or documentation before the Secretary of State will accept them. Most straightforward business names don't run into this, but it's worth checking before you get attached to a name.
How to search for an Ohio business name
Before you file anything, run your proposed name through the Ohio Secretary of State's Business Search tool. It's free and covers both registered LLC names and trade names (DBAs) already on file in Ohio.
A few tips for getting accurate results: remove special characters like apostrophes, commas, hyphens, and periods from your search term. The database won't match on those, so searching "Smith's Consulting LLC" won't return the same results as "Smiths Consulting LLC." Use the wildcard search — enter a percent sign (%) before or after a word — to broaden your results and catch names that are close but not identical to yours.
Finding no exact match is a good sign, but it doesn't guarantee your name will be approved. The Secretary of State evaluates distinguishability at the time of filing, so a name that looks clear today could conflict with a business that files before you do.
How to reserve or register your Ohio LLC name
You have 2 options for securing an Ohio LLC name: reserve it now and file your Articles of Organization later, or skip the reservation and register the name directly when you file your Articles of Organization.
Name reservation is optional in Ohio. It's useful if you've settled on a name but aren't ready to form your LLC yet — it holds the name while you get everything else in order. Reservation is filed with the Ohio Secretary of State.
If you're ready to move forward, filing your Articles of Organization registers the name at the same time. Once the state approves your filing, the name is yours. There's no separate name registration step required when you form the LLC.
Ohio DBA, trade name, and fictitious name
If you want to run your Ohio LLC under a name that's different from its legal registered name, you need to register that alternate name with the Ohio Secretary of State. Ohio calls these trade names or fictitious names — both are what most people mean when they say "DBA" (doing business as).
Ohio draws a distinction between the two. A trade name must be distinct on the Secretary of State's records and gives you exclusive rights to that name in Ohio. A fictitious name doesn't carry the same exclusivity — it can't include the name of an already-registered entity, and it doesn't prevent someone else from using a similar name.
To register either type, file a Name Registration (Form 534A) with the Ohio Secretary of State. You can file online through Ohio Business Central or by mail. The form asks for the DBA name, your LLC's legal name, your entity number, the nature of the business, your business address, and a signature from an owner or authorized representative.
Trademarks and your Ohio LLC name
Registering your LLC name with the Ohio Secretary of State doesn't protect you from trademark conflicts. State registration and federal trademark protection are separate systems, and a name that clears the Ohio business search can still infringe on a federally registered trademark.
Before you commit to a name, search the USPTO's Trademark Electronic Search System (TESS) at uspto.gov to check for existing federal trademark registrations. If another business holds a registered trademark on a name that's the same as or confusingly similar to yours, using it can put you on the hook for trademark infringement — even if Ohio approved your LLC filing.
If you're building a brand you plan to protect long-term, talk to a legal professional about whether federal trademark registration makes sense for your business.
FAQ
Use the Ohio Secretary of State's free Business Search tool at ohio.gov to check whether your proposed LLC name is already taken. Search without special characters like apostrophes or hyphens, and use the percent sign (%) as a wildcard to catch names that are close but not identical to yours. A clear search result is a good sign, but it doesn't guarantee approval — the Secretary of State makes the final call at the time of filing.
Yes, Ohio has specific naming rules for LLCs. Your name must include a required entity identifier — "LLC," "L.L.C.," "limited liability company," "limited," "ltd.," or "ltd" — and it must be distinguishable from every other business already registered with the Ohio Secretary of State. Minor differences like punctuation changes, adding "the," or switching singular to plural don't count as distinguishable. Certain restricted words also require additional approval before the state will accept them.
Yes. If you want to run your Ohio LLC under a name that's different from its legal registered name, you need to register that alternate name with the Ohio Secretary of State as a trade name or fictitious name. File Form 534A — the Name Registration form — online through Ohio Business Central or by mail. A trade name gives you exclusive rights to that name in Ohio; a fictitious name does not carry the same protection.
Yes. The Ohio Secretary of State allows you to reserve an LLC name before you're ready to file your Articles of Organization. Reservation is optional — if you're ready to form your LLC now, you can register the name directly by filing your Articles of Organization, which secures the name upon approval. Reservation is useful if you've settled on a name but need more time before forming the LLC.
The Ohio business entity search is the Ohio Secretary of State's free online database of registered business entities in the state. You can use it to look up existing LLCs, corporations, and trade names to check whether your proposed business name is already in use. It covers both active and inactive entities. Search at ohio.gov before filing any formation or name registration documents.
Ohio fictitious name registration lets your LLC operate publicly under a name that's different from its legal registered name. File Form 534A with the Ohio Secretary of State — online through Ohio Business Central or by mail. The form requires your DBA name, your LLC's legal name, your entity number, the nature of the business, your business address, and a signature. Unlike a trade name, a fictitious name doesn't give you exclusive rights to that name in Ohio.
No. Your LLC's legal name — the one on your Articles of Organization — doesn't have to match the name you use publicly. If you want to operate under a different name, register it as a trade name or fictitious name with the Ohio Secretary of State using Form 534A. Many business owners do this to keep their legal entity name separate from their brand name.
