Businesses are required to register with the Ohio Secretary of State to legally conduct business in the state — this is commonly called a business license. See Start a Business for more information.

Similarly, many businesses and professionals are required to hold certain licenses, certifications, permits, or registrations to work in their professions. Many licenses are issued and managed through the State of Ohio's eLicense system.
