The
Federal Information Processing Standard (FIPS) is used by the U.S. government to uniquely identify counties. In the following table, these codes link to the United States Census Bureau's "quick facts" for each county. Ohio's FIPS code of 39 is used to distinguish from counties in other states. For example, Adams County's unique nationwide identifier is 39001. Various state agencies identify counties by different coding schemes. The
Ohio Department of Taxation assigns
consecutive numbers for the purpose of enumerating taxing districts. The
Ohio Department of Public Safety, including the
Ohio Bureau of Motor Vehicles, associates these county numbers with vehicle registrations. The
Department of Transportation uses three-letter abbreviations in road inventory and traffic management applications. For historic preservation purposes,
Ohio History Connection refers to counties by two- and three-letter abbreviations in the Ohio Archaeological Inventory and Ohio Historic Inventory, respectively. ==See also==
