Ohio's 88 counties are identified by several coding schemes. This annex includes the transportation-related coding schemes.

The Ohio Department of Taxation assigns consecutive numbers for the purpose of enumerating taxing districts.[1] The Ohio Department of Public Safety, including the Ohio Bureau of Motor Vehicles, associates these county numbers with vehicle registrations.[2]

The Ohio Department of Transportation identifies counties using three-letter abbreviations in its road inventory and traffic management applications.[3]
