Ohio business name search: how to check if a name is available

What does it take to know a business name is available in Ohio?

"Available" means three different things, and owners who check only one of them are the ones who end up renaming a year later.

• Available on the Ohio record: the Secretary of State will accept the name on your articles or trade name filing. This is the only check with a legal test behind it.
• Clear of trademarks: nobody holds trademark rights that your use of the name would run into. The state business record does not settle this.
• Usable in practice: the domain, the social handles, and the local market are not already crowded with something close.

This guide covers all three, in that order. If you already ran a quick search and found the name taken, skip to the section on what to do when a name is not available. For the specific endings and words an LLC name must contain, see our guide to Ohio LLC name requirements.

How to run an Ohio Secretary of State business name search

The Secretary of State's online business search looks across the names on the state's business record. Run it the way the state will read your name, not the way your customers will.

• Drop the ending. Search "Lakeshore Roofing," not "Lakeshore Roofing LLC." The ending does not count as a difference, so a corporation called "Lakeshore Roofing Inc." is a conflict.
• Search the distinctive word alone. "Lakeshore" by itself shows you every name built around it, including ones that differ only by an extra "the" or a plural.
• Try the variations the state treats as the same: "and" for "&," a plural for a singular, an abbreviation such as "Bros." for "Brothers."
• If the name has a number, search it as a numeral and spelled out.
• Open any close result and look at its type and status. An LLC, a corporation, or a registered trade name can block you. A fictitious name report cannot.

Write down what you found and when. If you hand the filing to someone else, or file a week later, the notes tell them what you already ruled out.

A clean search is evidence, not a ruling. If a close call matters, the Secretary of State's filing forms offer a preclearance filing, an advisory review of a document before you formally submit it, for an added state fee. The forms list 1 to 2 business days for that review.

Which Ohio records is a new business name compared against?

The test is the same phrase in every statute: the name must be "distinguishable upon the records" of the Secretary of State. What changes is the list of records, depending on what you are filing.

Two details in that table catch people out. First, a fictitious name report is on none of the lists, because it claims no exclusive right. A fictitious name in the search results does not stop you from forming an LLC with the same words. Second, filed Ohio trademarks are checked only when you register a trade name. An LLC or corporation name is not tested against them, which is one reason a state approval says nothing about trademark risk.

How to read a close match in your search results

Your search turned up a name that looks a lot like yours. Is it a conflict? The Secretary of State decides distinguishability (ORC 1701.05(B); ORC 1329.02(B) applies the same approach to trade names). Division (B) of 1701.05 lists differences that do not count on their own: the words "corporation," "company," "incorporated," or "limited" and their abbreviations; an article, conjunction, contraction, abbreviation, or punctuation; and a different tense or number of the same word. The list is not exhaustive. Here is how it plays out, assuming "Lakeshore Roofing LLC" is already on the record:

The pattern is simple. Grammar and endings never create a difference. New words usually do. If your name and an existing one would sound the same when read aloud over the phone, assume trouble and pick something with a real difference in the words.

Words that can make an Ohio business name unavailable

A name can be distinguishable and still be refused because of what it says.

• Government connections. A corporation name may not indicate or imply a connection with a government agency of Ohio, another state, or the United States (ORC 1701.05(A)(4)). Trade names have the same bar (ORC 1329.02(A)).
• Implying incorporation. A trade name may not imply the business is incorporated when it is not (ORC 1329.02(A)). An LLC's brand name should not end in "Inc."
• "Benefit" endings. A corporation may not put "benefit" or "b-" before its ending unless it is a benefit corporation (ORC 1701.05(A)(2)).
• Missing endings. An LLC name must include "limited liability company," "LLC," "L.L.C.," "limited," "ltd.," or "ltd" (ORC 1706.07(A)); a corporation needs "company," "co.," "corporation," "corp.," "incorporated," or "inc." (ORC 1701.05(A)(1)).

Licensed professions and regulated industries can carry their own naming rules set by their licensing boards. If your name uses a professional title, check with the board before you file.

What to do when the business name you want is taken

Ask for consent

Both ORC 1706.07(C) and ORC 1701.05(C) let you use a name that is not distinguishable if the existing holder consents in a signed writing on the state's form, Form 590, Consent for Use of Similar Name. This works when the holder is related to you, such as a sister company, or simply willing. It rarely works with a stranger or a competitor.

Change the words, not the grammar

Add a place, a trade, or a family name. "Lakeshore Roofing of Medina" or "Kowalski Lakeshore Roofing" changes the words themselves. Search the new version from the top, because the new word can collide with something else.

Use the name as a fictitious name

If you only need the name for marketing, a fictitious name report records your use without claiming the name. Our Ohio trade name and DBA service files it. Whether using a name someone else holds creates other legal risk is a question for your attorney.

Out-of-state companies

A foreign LLC or corporation whose legal name is taken in Ohio registers under an assumed name for use here (ORC 1706.513; ORC 1703.04(C)(2)). Corporations attach Form 591. Our guide to Ohio foreign LLC registration walks through it.

One more trap: a name that looks inactive may still be held. When a foreign corporation's Ohio license is cancelled, ORC 1703.15 reserves its name for one year after the cancellation.

Do you need a trademark search too?

If the name will carry real marketing money, yes. A state name filing and a trademark are separate systems. The Secretary of State approves names under the distinguishability rules above. Trademark rights depend on who used a mark first, for what goods or services, and whether the public would confuse the two. An approved Ohio LLC name is not permission to use it against an earlier trademark owner.

There are two registers to look at. The U.S. Patent and Trademark Office keeps the federal register, which you can search on its website. Ohio keeps its own state register at the Secretary of State. An Ohio registration is filed on Form 555, and the Secretary of State's fee schedule lists $125. The applicant must be using the mark in Ohio and must include a specimen of the mark as actually used (ORC 1329.56). A registration lasts ten years and can be renewed (ORC 1329.58).

A search of both registers, plus a plain web search for the name with your trade, catches the obvious conflicts. Deciding whether a close mark is a real risk, and whether to register your own, is work for a trademark attorney.

Domains, handles, and the real world

None of these are tied to the state record, and none of them check it. A name can be approved by Ohio while the matching domain belongs to someone in another state. Before you file:

• Check the exact domain you want, and decide in advance whether a longer version (adding your city or trade) is acceptable.
• Check the handles on the platforms you will actually use.
• Search the name with your town and trade in a search engine and a map app. A business using a name without filing anything will not appear in the state search, but it will appear there.
• Say the name out loud the way you will answer the phone. If people mishear it as a competitor, that is a cost no filing fixes.

If the domain is free and the name passes the state check, it can be worth registering the domain the same day you file. Domains are first come, first served.

Business name search mistakes that cost Ohio owners money

Most rejected or regretted names come from a handful of habits. Each one is easy to avoid once you know it.

• Searching the full name with the ending. A search for "Lakeshore Roofing LLC" may not surface "Lakeshore Roofing Co.," which blocks you just the same.
• Treating a fictitious name as a block, or a trade name as harmless. A fictitious name report does not stop your LLC; a registered trade name with an exclusive right does.
• Buying signs, truck lettering, or a website before anything is filed. The search result can change the day after you run it. Only a filing holds the name.
• Assuming an LLC approval clears the trademark question. The state never compared your LLC name against trademarks.
• Forgetting the brand. If the LLC's legal name differs from the name on the truck, the truck name needs its own trade name or fictitious name filing. Our guide to Ohio DBA vs. LLC explains how the two fit together.
• Picking a name that only works in one city. If you might expand, a name tied to one suburb can feel cramped later, and renaming means an amendment, new signs, and updated accounts.

A good rule of thumb: run the state search, the trademark search, and the domain check on the same day, then file within days, not months. The longer the gap, the more you are relying on a search that is getting stale.

Once the name is clear: how to lock it in

A search holds nothing. The name stays open to anyone until a filing puts it on the record. You have three ways to do that:

• Form the entity. Filed LLC or corporation articles hold the name for as long as the entity exists. The state fee is $99, and our Ohio LLC formation service files it with the name check included.
• Reserve the name. A reservation under ORC 1706.07(E) or 1701.05(E) holds it for 180 days for $39. It makes sense when there is a real gap before you can form; see our Ohio name reservation service.
• Register a trade name. If the name is a brand for a business that already exists, a trade name registration with an exclusive right puts it on the list other filers are checked against.

Forming an LLC or corporation also means naming an Ohio statutory agent at an Ohio street address in the articles. Pick the agent before you file so the name and the agent go in together. If the entity already exists and you are renaming it, the name change is an amendment to the articles, which our amendment service prepares.
