ohio sos entity search points at an office, not just a database: the Ohio filing authority - Ohio Secretary of State - is the legal custodian of the state's entity records, and its search is the public window into what it holds. Knowing what belongs to this office and what lives elsewhere (courts, revenue, licensing) is what makes the search useful. This page maps the office's actual records and links the way in.
What the filing office holds
The custodian's records in Ohio are the entity register - formations, amendments, dissolutions, agent designations, periodic reports - and in most states the assumed-name and UCC lien indexes beside it. Each record is a filing the office accepted, timestamped and made public; the search at Ohio Secretary of State reads that file directly, and our Ohio page links it. What arrives through the office is what exists; a company with no file here and no foreign registration is not a Ohio entity. Ohio pairs its free business search with a published name-availability guide, and the searchable business database includes filing images, not just index rows.
What lives elsewhere on purpose
Tax accounts and standing sit with the revenue department; lawsuits with the courts; professional and trade licenses with their boards; trademarks federally with the USPTO and, where Ohio runs one, in a separate state register. The filing office will not warn you about any of them. Diligence that stops at the entity record is a third done - but diligence that starts anywhere else lacks the legal name and file number that anchor every other search.
Using the office's search well
The official search rewards the custodian's own conventions: starts-with and contains modes, stems rather than exact strings, and attention to the office's indexing quirks - punctuation and entity endings often ignored, former names sometimes searchable. Results link the actual filings, and certified versions of any of them are available from Ohio Secretary of State at published fees where formality is needed. The lookalike sites reselling this data add nothing but staleness; the office's own answer is the one a court will recognise.
Questions people ask about ohio sos entity search
Is the official search free?
Yes; reading the register at Ohio Secretary of State costs nothing. The office charges for certificates and certified copies, at fees its own schedule publishes.
Does the office's record cover taxes or licenses?
No; revenue and licensing authorities keep those separately. The filing office certifies registration facts only.
Why do third-party sites outrank the official one?
They spend on search placement and resell the office's data, usually staler. The authoritative record is the custodian's own, linked from our Ohio page.
Can I get official copies of what I find?
Yes; the office sells plain and certified copies of its filings at published fees - the formal versions counterparties and other states ask for.
