Ohio Secretary of State Charter or Registration Number Required

Ohio Revised Code Chapter 4733 requires that your firm must have an active Ohio Secretary of State charter or registration number in order to complete a Certificate of Authorization. You can search Ohio’s Secretary of State website to find your firm's charter or registration number (Entity Number on SOS look up results).

From the Ohio Secretary of State Website

“Anyone who is planning to do business within the state of Ohio, using a name other than their own personal name, must register with our office… This applies to companies in Ohio and companies in other states or countries wishing to do business in the state of Ohio. Companies outside the state of Ohio often have to include a Certificate of Good Standing from their home state’s Secretary of State or registering authority to accompany their filing.”

Certificate of Authorization Application Packet

Additional Affidavit of Responsibility Form 3012

Completed Certificate of Authorization applications with fee must be received no later than a minimum of 7 days before a regularly scheduled board meeting in order to be considered for approval at that meeting.

The Certificate of Authorization application requires that names and addresses of all owners of the company be included with the application — a list of officers will not suffice. If an owner is an officer, please state that. In addition, if the company is owned by another corporation, you must list the ownership of that company. For example: “ABC LCC is owned by ABC, Inc. which is a publicly traded company,” or list the owners of said company.

If the company is employee-owned, you must state that and include the names and addresses of the individual owners. If the ownership information is not included, the application will be returned as incomplete.
