How to search Ohio business entities online

Updated August 2026

Quick Answer

Ohio's business search is at businesssearch.ohiosos.gov, run by the Secretary of State. Search by business name, prior name, statutory agent/registrant, organizer, or Document ID/Entity Number — six modes in all — to see the entity's status and filing history free, no account needed. Filing anything — not just searching — can be done either through an online account or by paper submission, unlike states that have gone fully digital.

  1. Go to businesssearch.ohiosos.gov.
  2. Search by business name, statutory agent, organizer, or Document ID/Entity Number.
  3. Review the result for the entity's status and filing history.

What the search covers

The database covers for-profit corporations, nonprofit corporations, professional associations, foreign corporations and foreign name registrations, business trusts, real estate trusts, limited liability companies, limited liability partnerships, and limited partnerships, along with fictitious names, trade names, name reservations, trademarks, and service marks — all in the same system.

Coverage has some historical gaps: filings before 1973 were maintained manually and were only computerized for businesses still active at that time, and document images are complete only from 1997 forward (earlier filings were microfilmed).

Search options — six modes

Ohio's search is more flexible than most state portals:

  • Business Name — standard name search with Begins With and Contains options, filterable by status (All, Active, Cancelled, Dead, or Fraudulent)
  • Exact Business Name — matches the exact name only
  • Prior Business Name — searches former names for entities that have been renamed
  • Agent/Registrant — the statutory agent for most entities, or the registrant name for trade names, trademarks, and similar filings
  • Organizer/Incorporator — finds all entities organized by a specific individual or organization, with an optional location-of-incorporation filter
  • Number Search — by Document ID or Entity Number (this serves as the charter number for domestic corporations, license number for foreign corporations, or registration number for LLCs, LPs, LLPs, trade names, and similar filings)

A separate Trademark/Service Mark search covers mark number, mark description, and registrant name.

Ohio's no-annual-report policy

Ohio does not require annual reports for most business entities — no LLC annual report, no corporation annual report. This is one of the most significant cost and compliance advantages in Ohio's business environment. LLPs are the main exception, filing a biennial report between April 1 and July 1 of odd-numbered years ($25 for both domestic and foreign LLPs). Confirm current requirements for specific entity types at ohiosos.gov, as rules can change.

The absence of annual reports also means Ohio's database does not automatically show whether entities have been actively maintained. A record showing "Active" status reflects the formation date and any amendments — it does not indicate the entity filed a recent report, because there is no such report to file.

What Ohio's unusual status labels mean

Ohio's status filter includes options most states don't use the same way. Dead is the umbrella label for a domestic corporation that's no longer legally active — it covers both a corporation that voluntarily filed a certificate of dissolution and one whose articles were administratively cancelled, and it's the same term Ohio uses on its official public Cancelled/Dissolved Corporations report for anything that closed within the past 5 years. Fraudulent is a different, much rarer status: it's only applied after the Secretary of State's Public Integrity Division investigates a complaint and determines a specific filing was unauthorized or fraudulent, at which point the record is permanently cancelled, marked as fraudulent on the public record, and any unauthorized names or addresses in it are redacted.

A cancelled entity has a real deadline to come back from: reinstatement is only available up to 2 years from the cancellation date, after which Ohio treats the cancellation as permanent.

Frequently Asked Questions

Can I search Ohio's business database by a company's former name?

Yes. The 'Prior Business Name' search mode looks up former names for entities that have since been renamed, one of six distinct search modes Ohio offers alongside Business Name, Exact Name, Agent/Registrant, Organizer/Incorporator, and Number Search.

Does Ohio's business search go back before 1973?

Only partially. Filings before 1973 were maintained manually and were computerized only for businesses still active at that time; document images are complete just from 1997 forward, since earlier filings were only microfilmed.

Does an 'Active' status in Ohio's business search mean the company recently filed something?

Not necessarily. Ohio doesn't require annual reports for most entities, so an Active status just reflects the formation date and any amendments — there's no recurring report to indicate recent activity.

What does a 'Fraudulent' status mean on an Ohio business search?

It's a rare, complaint-driven status — Ohio's Secretary of State only applies it after its Public Integrity Division investigates and confirms a filing was made without authorization. The record is then permanently cancelled and marked fraudulent, with any unauthorized names or addresses redacted.

How long do I have to reinstate a cancelled Ohio business?

Two years from the cancellation date. After that, Ohio treats the cancellation as permanent and reinstatement is no longer available.
