Does a name being available mean I own the trademark?

No. Name availability at the Secretary of State only means no conflicting Ohio entity exists. Trademark rights are separate; you should also search the USPTO database and Ohio trademark and trade name records before you rely on a name.

Q: How do I check if a business name is available in Ohio?

Search your desired name in the Ohio Secretary of State Business Search. If no active entity is on file with a name that is not distinguishable from yours, the name is likely available. Ohio requires names to be distinguishable on the record under Ohio Revised Code Section 1706.07.

Q: What is an Ohio charter or registration number?

It is the unique entity number the Ohio Secretary of State assigns to each registered business. You can search by this number in the Business Search and it appears on your filing confirmation and business records.

Q: Does an Ohio business search show the owners of an LLC?

Not usually. Ohio Articles of Organization (Form 610) do not require listing members, so the Business Search typically shows the entity name, status, statutory agent, and filing history rather than owners.

What the Ohio Business Search Tells You

The Ohio Secretary of State Business Search is the state's official, public database of every business entity on file - limited liability companies, corporations, limited partnerships, and registered trade names. It is maintained by the Ohio Secretary of State's Business Services Division and is free to search without an account. Because it is the same registry that accepts your Ohio LLC formation, it is the authoritative place to confirm whether a business name is already taken.

For each entity, the search returns the exact legal name, entity type, current status (active, cancelled, dead, or hold), the assigned charter or registration number, the effective date, the statutory agent and agent address, and a list of documents filed with the state. You can use it to verify a vendor is a real registered entity, to look up your own charter number, to confirm a competitor's status, or - most commonly - to check that the name you want for a new LLC is available before you pay the filing fee.

How to Run an Ohio Business Entity Search

The search is straightforward and takes under a minute. There is no charge to view results.

Open the Business Search. Go to the Ohio Secretary of State Business Search at businesssearch.ohiosos.gov, reachable from the Secretary of State business services pages.
Choose a search type. You can search by business name, by charter or registration number, or by the name of a statutory agent to find every entity an agent represents.
Enter your term and use partial matching. Type the distinctive part of the name rather than the full designator. Searching "acme" surfaces more potential conflicts than searching "Acme Widgets LLC," because the state compares the distinguishable core of the name.
Review the results list. Each row shows the entity name, type, status, and number. Click an entity to open its detail page and full filing history.
Open filed documents. From the detail page you can view or order images of filings such as the Articles of Organization, amendments, and statutory agent updates.

Search Tips: Name, Charter Number, and Agent

Ohio compares names on a distinguishable-on-the-record standard, not an identical-match standard, so small tweaks do not make a taken name available. Punctuation, capitalization, the entity designator ("LLC" vs "L.L.C."), and words like "the," "a," and "and" are generally ignored when the state decides whether two names conflict. To search thoroughly, run several variations: the singular and plural, alternate spellings, and the name with and without a middle word. If any active entity's core name matches yours, choose a different name.

Searching by charter/registration number is the fastest way to pull up a specific entity when you already have its number from a contract or a prior filing. Searching by statutory agent name is useful for due diligence - it reveals every Ohio entity a particular agent or agent company is listed on, which can help you confirm a service provider or map out related companies.

Checking Name Availability Before You File

A clear search result is a strong signal, but availability is only final when the Secretary of State accepts your filing. Under Ohio Revised Code Section 1706.07, an LLC name must be distinguishable on the records of the Secretary of State from the name of any other entity or reserved or registered name. Related naming rules for LLCs appear in ORC 1706.16, and the same distinguishability principle governs corporations and trade names. If your name clears the search but you are not ready to file, you can reserve it: an Ohio name reservation holds a name for 180 days for a $39 fee, filed with the Secretary of State.

The search does not check trademarks, domain names, or local assumed-name records, so clearing the Business Search is necessary but not sufficient. Once your chosen name is confirmed, the next step is to file the Articles of Organization (Form 610) for the $99 state fee, which is the document that actually creates the LLC. See Ohio LLC cost for the full fee picture.

Reading the Results: Status, Type, and Filings

Entity status is the most important field. "Active" means the entity is in good standing and on the record. "Cancelled" or "Dead" means the entity is no longer active, which can happen after a voluntary dissolution or an administrative cancellation. Because Ohio does not require LLCs and corporations to file an annual report, Ohio entities do not lose good standing simply for missing an annual filing the way they do in many other states - a key difference explained on our Ohio annual report page.

The entity type field distinguishes a domestic LLC from a corporation, nonprofit, partnership, or a foreign entity registered to do business in Ohio. The filing history lists each document the entity has filed, with dates, so you can see when it formed, whether it has amended its Articles, and whether it has updated its statutory agent. This history is what banks, courts, and other states rely on to confirm an entity exists. If a filing you expect is missing, it may still be in processing, or the entity may have filed under a slightly different legal name, so search a few variations before concluding a document was never filed with the state.

Ordering Certified Copies and Certificates of Good Standing

The free search shows entity data on screen, but some transactions - opening certain bank accounts, registering to do business in another state, or closing a loan - require an official document. The Ohio Secretary of State issues certified copies of filings and a Certificate of Good Standing (also called a certificate of full force and effect) confirming an entity is active and up to date. These are paid services ordered through the Secretary of State; the free Business Search is where you find the entity first, then request the certificate. Confirm current certificate and copy fees on the Secretary of State's filing forms and fees pages before ordering.

Trademark and Trade Name Searches Beyond the SOS

Clearing the Business Search does not give you exclusive rights to a name. To protect a brand, also search federal trademarks in the U.S. Patent and Trademark Office database and consider Ohio's own trademark and trade name (DBA) records, which are filed under Ohio Revised Code Chapter 1329. A registered Ohio trade name gives its holder exclusive statewide rights to that name, so an available entity name can still conflict with a registered trade name or a federal trademark. Run all of these checks before printing signage or buying a domain. See our trademark overview for how the federal and state systems interact.

Limitations of the Business Search

The Business Search is a naming and status tool, not a complete public-records portal. It does not list the members or owners of an LLC, because Ohio's Articles of Organization do not require disclosing them; if you need ownership information you may have to review contracts or other records. It also does not show tax standing with the Ohio Department of Taxation, local vendor's license status, or professional licensing. And a name that is available today can be taken tomorrow, so re-check immediately before filing. When you are ready to move from research to filing, follow our step-by-step Ohio LLC guide and get a federal EIN for the new entity.

It is the unique number the Secretary of State assigns each registered entity. You can search by it, and it appears on your filing confirmation and on the entity's detail page.
