Searching for a Business Name in Ohio
The Ohio Secretary of State publishes a free business search covering every registered entity in the state. It needs no account, it is the office that examines your filing, and it is the only record that decides whether a name is available.
Ohio is also the most generous state on this list for reservations: 180 days, against 60 in New York and California. If there is a real gap between settling on a name and filing, Ohio gives you six months of it — and the rules below are what the name has to satisfy when you do file.
Free state search
The Secretary of State's business search is public and costs nothing. No account and no third-party site needed.
180-day reservation
The longest hold of the five states covered here — six months between choosing a name and filing.
Flexible endings
Ohio accepts LLC, L.L.C., limited liability company, limited, ltd. and ltd as the ending of an LLC name.
How to Search the Ohio Business Name Database
Open the Secretary of State's business search
Ohio's search at businesssearch.ohiosos.gov covers registered entities across the state. It is free, needs no account, and reflects the records the examiner will check your filing against.
Search without the suffix
Search the distinctive words alone. Including "LLC" hides conflicts with corporations using the same distinguishing words, and those conflicts are what get a filing rejected.
Check the obvious variants
Singular against plural, digits against spelled-out numbers, and close respellings. Ohio requires a name to be distinguishable upon the records, which punctuation and spacing alone do not achieve.
Reserve for 180 days, or file
A name reservation holds an available name for 180 days in Ohio. It is optional — the Articles of Organization claim the name — but the six-month window is long enough to be worth using.
Pro tip: Ohio's registry sits in the first three organic results for most searches, which is a good sign for you: it means the state's own record is easy to reach and there is no reason to pay a third party for the lookup.

The Secretary of State's own free search. We hold no registry records and make no availability claim — the state is the only office that decides.
Nametastic is not a law firm and this is not legal advice. We hold no registry records and cannot tell you whether a name is available — only the state can. Naming rules change; confirm the current requirements with the office linked above before you file.

| Do | Not this | |
|---|---|---|
| Entity ending | End with limited liability company, LLC, L.L.C., limited, ltd. or ltd | Leave the ending off, or use a corporate suffix on an LLC |
| Distinguishability | Make the distinctive words differ from names already on the records | Rely on punctuation, spacing or capitalisation to separate the name |
| Restricted words | Check whether bank, trust, insurance or similar require another agency's approval | Assume availability in the search means the word is permitted |
| Misleading names | Keep the name consistent with the company's actual activity | Imply a licensed profession or public body you are not |
| Trade names | Register a trade name separately if you will operate under a different name | Assume the entity filing protects a trading name it does not contain |
Getting an Ohio Name Through First Time
- 1
Use the long reservation
180 days is unusual. If you are still assembling partners, funding or a lease, Ohio's reservation actually covers the gap rather than expiring halfway through it.
- 2
Decide the ending deliberately
Ohio permits "limited" and "ltd." as well as "LLC". They read very differently on a sign and on an invoice, and the choice is yours rather than the statute's.
- 3
Search suffix-free, always
The conflict that rejects your filing is usually an entity of a different type with the same distinctive words. Only a suffix-free search surfaces it.
- 4
Pair the name with a domain check
Ohio will register a name whose domain has been parked since 2009. Check both in one pass — the generator above shows live domain availability alongside each suggestion.
- 5
Bring a fallback
Distinguishability is judged at examination, not in the search box. A second name you would genuinely use is the cheapest insurance against a second filing cycle.
