Ohio business name search

Check an Ohio business name before you file.

Start with the Ohio Secretary of State's business search, then compare your proposed name with the state's naming rules. A search result is a starting point for a filing decision. It does not give you trademark clearance or hold a name while you decide.

Official sources checked September 13, 2026. This guide explains public filing procedures and does not determine whether a particular proposed name will be accepted.

Start at the official search

The Secretary of State's Business Services page links directly to the Ohio business search and the current online filing portal. Use those official links rather than an advertisement offering to run the search for you.

1. Write down the proposed name exactly as you intend to file it, including an entity ending such as LLC.
2. Look for that name in the official search. Also look for the distinctive words on their own so you can inspect nearby names.
3. Read the relevant records and note their names and statuses. Keep the record details with your notes instead of relying on a screenshot of a results count.
4. Compare the proposed name with the state's name-availability guide before selecting a filing.

These are suggested research steps. The search interface may change, and this guide does not reproduce its controls. If the database is unavailable or the result is unclear, return to Business Services for the filing office's contact details. A temporary access problem is not a name-availability result.

What an Ohio LLC name needs

Ohio Revised Code section 1706.07 requires an LLC name to include "limited liability company" or a permitted abbreviation. The permitted forms include LLC and L.L.C. The same section requires distinguishability from specified existing entities and registered trade names, subject to its exceptions.

Ohio's availability guide explains that punctuation, articles such as "the," and certain abbreviations do not make otherwise conflicting names distinguishable. It also identifies restricted wording, including language that improperly implies government affiliation. Adding a period or an article is therefore a poor starting point for resolving a conflict.

Keep two or three genuinely different candidates in your notes. For each one, record the exact wording and any nearby records you found. This makes an inquiry to the filing office more concrete than asking whether an unnamed variation is "close enough." An attorney can advise on rights or disputes that go beyond the filing search.

Holding an LLC name while you prepare

Section 1706.07 allows an available LLC name to be reserved for 180 days, with the filing date counted as the first day. The statute also provides for transferring the reserved right through a filing. A reservation holds the name; it is separate from the articles used to organize the LLC.

The state publishes Form 534B, Name Reservation/Transfer/Cancellation. Read the current form and its instructions, and use the official filing portal for the available online process. Check the fee and service option at the time of filing. This page does not quote a processing time or fee that could change.

If you make a reservation, keep the accepted filing with the spelling of the reserved name and its expiration date. Calendar the deadline alongside the remaining formation tasks. Do not treat an unfinished reservation application as a confirmed hold.

Trade name or fictitious name: Ohio treats them differently

People often use "DBA" for a business's operating name. Ohio's official terminology separates a trade name from a fictitious name. The state's guide says trade names must meet its distinguishability requirements; fictitious names do not, and multiple businesses can use the same fictitious name. Read the state's explanation of name types before choosing a registration.

A fictitious-name record in your search therefore needs a different interpretation from an existing LLC or registered trade name. Keep the record type in your notes. Ask the filing office about the procedure if you cannot tell which application fits; seek legal advice about the protection or obligations you need.

Keep the trademark question separate

A state filing search and a federal trademark search look at different records. Use the USPTO's trademark-search resources for the federal database and its guidance on searching similar marks. A matching web domain or a clear state search is not a substitute for considering trademark rights.

Before paying for signs, packaging or a large print run, confirm the filing outcome and get professional advice where the name creates uncertainty. NameUSA does not provide a clearance opinion.
