In only five quick steps, you can learn a world of information about your business—and your potential competitors.

1. Visit the Ohio government website

In your browser, navigate to the Ohio Secretary of State's website. While the websites of most government entities are protected, always make sure that you're on the official state website, not the website of a third-party service.

2. Access the business search function

On the official Ohio Secretary of State website, navigate to the Business Services page. There, you'll find a number of resources for Ohio-based businesses, from directions for business filings to a business search feature.

3. Enter your search criteria

Once you've reached the Ohio Business Search website, the page conducts a brief security check, which asks you to verify you are human. Then, you'll be allowed to search businesses in the state using a variety of information, such as business name, entity number, or the reference ID listed on their paperwork.

4. Review the results

After a few seconds, you'll be given a complete list of the Ohio-based businesses that match your search. Based on whether or not these meet your needs, you can narrow or broaden your search criteria for a better selection.

5. Check specific business details

Now that you've found a list of the Ohio businesses most relevant to you, browse through them to find the information you need. Depending on your situation, this could be anything from the registered business name to the number of businesses in your specific niche.

Visiting the Ohio Secretary of State website takes only a few minutes, but it can yield impressive benefits.

Legal naming requirements

Like many other states, Ohio has strict regulations for how you can name your business. These include:

  • Distinguishability: Any new business must choose a name that is distinguishable from existing businesses in Ohio.
  • Language restrictions: New businesses cannot use words like "bank," "insurance," or anything indicating government affiliation without specific pre-approval.
  • Entity designation: Business names must indicate the structure of that business, such as limited liability company (LLC) or corporation.

Business registration

By doing your research ahead of time, you can streamline the business registration process and avoid any unfortunate hiccups along the way.

Competitor insights

Beyond what it means for your business, a statewide business search can also give you invaluable information about your industry and any competitors your new business might encounter. This, in turn, can help you make smarter decisions in the crucial early days of your new business venture.

Naming considerations to remember

Naming your new business is perhaps one of the most thrilling aspects of becoming a business owner, but there are some things to remember when doing so.

Check if your domain name is available

Even if your business name is available within Ohio, the related domain name may already be taken. In order to maximize your branding and online presence, it's best to find a name available in-state and online.

Conduct a trademark search

Trademark infringement causes more headaches and litigation than you could imagine. Because of this risk, always check whether your business' name might infringe on the rights of an established business entity (especially if that entity is especially litigious).

FAQs

How do I know I'm on an official state website?

As a rule, all state and federal websites end with .gov in their URLs. While this is only one way of many that you can check a website's credibility, it's one of the first things to look for.

What if I need more help with my business search or registration?

If you encounter a problem accessing the state website or have more questions, consider calling your state's office directly. While it may take a little time, they'll often have people available to help.

How do I find a business' information with just their website?

A business' IP address and reference ID are linked, meaning that you can use the IP address of their website to find registered information about that business online.
