Ohio’s reputation as a logistics hub, coupled with its dynamic economy and business-friendly tax structure, makes it a magnet for entrepreneurs and established enterprises.
The state’s 1.1 million registered business entities drive its thriving economy. According to the 2024 Small Business Administration (SBA) report, Ohio welcomed 2,764 new establishments in 2023 alone. Behind every successful business in Ohio is a foundation built on proper registration and compliance. All entities, from corporations to partnerships and nonprofits, are officially recorded with the Ohio Secretary of State (SOS).
Understanding how to navigate Ohio’s business search tool is a vital first step for aspiring entrepreneurs. Here’s how to perform the business entity search in the state:
Visit the Ohio SOS Business Search Page
The Ohio SOS offers a detailed and accessible database of all registered businesses in the state.

To utilize this resource, individuals can navigate to the official Ohio SOS website. By selecting the “Businesses” tab in the header and scrolling down, they will find the “Business Search” option.

For direct access, users can visit the portal at https://businesssearch.ohiosos.gov/.
Search Using the Preferred Search Criteria
Users have to complete a brief security check to confirm they are not robots. Once cleared, they can search for businesses within the state using various criteria, such as the business name, entity number, or reference ID from official documents.

The portal provides additional guidelines for search terms for accurate results. Special characters, including double quotes, apostrophes, commas, hyphens, periods, and others, should be excluded from the search. Consecutive single characters followed by punctuation should be treated as a single word. Failing to follow these formatting rules may result in incomplete or incorrect search results. Users can also choose one of the available filters beneath the search box. By default, the query will return unfiltered results, but users can refine their search by selecting from the following options:
- All
- Active
- Canceled
- Dead
- Fraudulent
After typing the search term and selecting the preferred filter, users can click the “Search” button to run the query.
Find the Ohio Business Entity in the Search Results
Once the search is prompted, a list of businesses matching the entered criteria will be displayed. Users can modify the search filters or adjust their criteria to narrow or expand the selection for a more precise match. The results will be shown in a table with a summary for each business.

The summary for each business will include the following information:
- Entity number and name
- Business Type
- Filing Date
- Expiration Date
- Status
- Location
- County
- State
Users can click the “Show Details” button next to a record to view more detailed information about a specific business.
Access the Ohio Business Entity Details
Once users have located the desired entity in the search results, they can review the details to find more information.

The Business Details section offers a quick overview of the business’s registration status and essential dates. The business’s details page URL can be saved for future reference. Users can purchase additional documents, such as a Certificate of Good Standing, for further verification if needed. The portal also offers email alerts to help protect business owners from potential threats, such as identity theft.

Why Do an Ohio Entity Search?
Searching for a business entity in Ohio is important for various reasons, whether for general business purposes or due to the state’s distinctive legal and economic environment. Below are key reasons to perform an entity search:
- Checking Business Name Availability։ Confirming that the desired business name is available is important before registering a business in Ohio, as it helps avoid conflicts or delays in the registration process. Ohio has specific naming regulations that must be followed. Business names must be distinguishable from existing entities to avoid confusion, and certain words, such as “bank” or “insurance,” require special approval. Additionally, names must include an entity designation like “LLC” or “Inc.” to reflect the business’s legal structure.
- Looking Up Business Information and History։ Entity searches provide critical details such as agent information and registered addresses. The lookup enables direct communication with agents or confirmation of legitimacy. Researching a company’s history and current standing before making a purchase or investment also helps avoid costly mistakes and gain insights into its operations and stability.
- Researching Industry Competition and Market Changes։ Ohio’s diverse economy spans industries like professional services, transportation, and construction, which makes it essential for businesses to understand the competitive landscape. A business entity search helps entrepreneurs identify key players within their sector or region. Additionally, with constant market shifts, regular entity searches allow businesses to track openings, closures, and emerging trends.
- Performing Due Diligence for State Contracts։ With over 2.1 million small businesses in Ohio, securing government contracts presents a valuable opportunity for companies. A business entity search checks that contractors meet all legal requirements, operate within state regulations, and hold necessary licenses, if applicable. This due diligence can mitigate potential legal and financial risks.
- Preventing Business Identity Theft։ Regularly monitoring corporate records through entity searches is a proactive measure to prevent business identity theft in Ohio. By keeping track of the company’s public filings, owners can quickly identify any unauthorized changes to their information.
Who Holds Data for Ohio Business Entity Search
Along with the Ohio SOS (Secretary of State), various other officials and departments are responsible for maintaining business entity data within the state. These include:
Ohio Department of Commerce
The Ohio Department of Commerce serves as a regulatory authority for numerous industries. It manages licensing, certification, and inspection processes for professionals and businesses operating in fields such as construction, finance, and fire safety. Its primary “Look Up a License” tool allows users to verify credentials and compliance for BBS building departments, consumer finance professionals, fire protection system designers, and corrective action specialists.
Under the Division of Industrial Compliance Search, the department also provides access to specialized databases for certified backflow inspectors, elevator records, bedding registration, and boiler contractor lists.
Ohio Department of Insurance
The Ohio Department of Insurance (ODI) regulates licensing for insurance agents and agencies, monitors market practices, addresses consumer complaints, and enforces state insurance laws. It keeps comprehensive records of licensed insurance agents and agencies operating within the state. Through its online Agent/Agency Locator, individuals can search for both individual agents and business entities.
This tool helps verify licensure so that consumers can be assured they are working with legitimate professionals or organizations.
Ohio Environmental Protection Agency
The Ohio Environmental Protection Agency (EPA) is dedicated to protecting the state’s natural resources by enforcing environmental regulations for businesses. The agency is responsible for monitoring air and water quality, overseeing waste management, and implementing programs that promote sustainable practices.
Businesses in Ohio can use the EPA’s eDocument Search tool to access important records, including permits issued to companies, compliance evaluations, and complaint reports. This resource is particularly useful for verifying a company’s adherence to environmental regulations or investigating its environmental performance.
Ohio State Board of Pharmacy
The Ohio State Board of Pharmacy regulates the state’s pharmacy profession and licenses pharmacists, pharmacy interns, and pharmacies. It also provides various online tools for both the public and professionals. The License Lookup tool allows users to input a license number to check the status and details of a pharmacist or pharmacy’s licensure.
Additionally, its Ohio Pharmacy Accessible Services Search helps identify pharmacies offering services for individuals with low vision, hearing impairments, or language translation needs. This initiative, in compliance with Ohio Administrative Code 4729:5-2-05, mandates pharmacies to accommodate diverse patient needs and promote inclusive access to services.
Ohio Bureau of Workers’ Compensation
The Ohio Bureau of Workers’ Compensation (BWC) oversees the administration of workers’ compensation insurance for employers and employees throughout the state. Its mission is to promote workplace safety and provide financial support to employees who experience work-related injuries or illnesses.
The BWC maintains records related to claims, employer accounts, and approved healthcare providers. Both employees and employers can utilize the BWC’s provider lookup tool to locate certified insurance providers within the workers’ compensation network. Employers can also review their account status, access claims information, and find safety resources.
Ohio Department of Job and Family Services
The Ohio Department of Job and Family Services (ODJFS) manages the state’s employer records and unemployment compensation data. The department offers a key resource: OhioMeansJobs.com, a platform that connects job seekers with employers.
This tool, part of the official Ohio state government website, includes detailed information about companies with job openings.
County Clerk’s Offices
County clerk’s offices across Ohio handle records related to businesses operating within their jurisdictions. These offices handle various filings that the state and other county-specific business documentation may not require. In addition to business filings, county clerk offices keep property records linked to business locations and manage local tax records or liens for compliance with county regulations.
They also verify the legal standing of entities that may not be subject to state-level filings. Records can be accessed by visiting the county clerk’s office in person or through their official website.
Federal Agencies
Federal agencies maintain essential records for Ohio businesses, especially those involved in interstate commerce or requiring federal oversight. The U.S. Patent and Trademark Office (USPTO) stores records for businesses with federally registered trademarks. These records include details about trademark applications, registration statuses, and the protections granted to trademark holders so intellectual property rights are upheld. Similarly, the Internal Revenue Service (IRS) holds data on businesses’ federal tax obligations.
Records include Employer Identification Numbers (EINs), tax filings, and any outstanding tax liabilities or penalties. These records are useful for verifying a business’s financial standing, compliance with tax laws, and overall operational health.
Commercial Database Providers
Commercial database providers, such as Dun & Bradstreet (D&B), Experian, and LexisNexis, offer extensive business data aggregated from state, local, and federal sources. These platforms make searching for information such as credit risk assessments, business ownership verification, and competitive industry insights easy.
What Are Different Entities You Can Register in Ohio?
Selecting a business structure is a pivotal decision for entrepreneurs in Ohio, often requiring guidance from an attorney and accountant. This choice impacts critical aspects such as taxation, personal liability, management responsibilities, continuity, ownership transfer, and the level of regulatory compliance required. In Ohio, businesses commonly operate under one of the following legal structures:
- Corporation։ A corporation is an independent legal entity owned by shareholders. Businesses must register as a C Corporation before applying for S Corporation status with the IRS. In an S Corporation, shareholders pay taxes on earnings, while the corporation itself avoids federal taxation. However, C Corporations experience double taxation because both corporate earnings and shareholder dividends are taxed. Shareholders are only liable for their own actions and the company’s obligations, with business assets being targeted first in legal disputes. Corporations benefit from the ease of transferring ownership through share sales, but personal assets can still be at risk. Corporations in Ohio are required to register using Form 532A.
- Limited Liability Company (LLC)։ An LLC combines liability protection with operational flexibility. LLCs can be owned by individuals, corporations, or other entities and are managed by members or designated managers. This structure allows members to report business income on their personal tax returns, as the IRS does not treat LLCs as separate tax entities. LLC members are generally shielded from personal liability, although they are accountable for their own actions. While LLCs provide strong protection for personal assets, transferring management duties requires unanimous approval from all members. Businesses forming an LLC in Ohio must submit Form 610.
- Limited Liability Partnership (LLP)։ An LLP is designed for partnerships seeking limited liability without transitioning into an LLC. In an LLP, all partners can directly manage the business and are shielded from liability caused by the negligence of other partners. Each partner is required to report their share of the business’s income on their individual tax return. The primary advantage of an LLP is its single-tax structure, but personal assets may still be exposed in some legal scenarios. Ohio requires the filing of Form 535 for LLP registration, whether the partnership is in-state or foreign.
- Limited Partnership (LP)։ An LP involves at least one general partner, who manages the business and holds personal liability for its debts, and one or more limited partners, who contribute capital but do not participate in management. Limited partners’ liability is confined to their investment in the partnership, while general partners are exposed to personal liability for business obligations. Limited partnerships are advantageous for protecting the assets of limited partners, but the general partners face increased risk. LPs in Ohio must file Form 531A to register.
- General Partnership։ A general partnership arises when two or more individuals agree to co-own and operate a business for profit. In this structure, all partners share responsibility for the business’s debts and obligations. While general partnerships are simple and cost-effective to establish, they offer no liability protection for personal assets. Registration is not mandatory, but general partnerships in Ohio can file a trade name, fictitious name, or Statement of Partnership Authority for recognition.
- Sole Proprietorship։ A sole proprietorship is the most basic entity form, where a registrant owns and manages the entire business. The business owner is personally responsible for all liabilities and debts of the business. Business income and expenses are reported on the owner’s personal tax return. Sole proprietorships are easy to establish and do not require partnership agreements, but personal assets are highly exposed in legal or financial disputes. To register a trade or fictitious name in Ohio, sole proprietors must file Form 534A.
