Editing List of counties in Ohio (section)

==List of county codes==
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.<ref name=FIPS>{{cite web |url=https://www.epa.gov/enviro/county-fips-code-listing-state-ohio |title=County FIPS Code Listing for the State of OHIO |publisher=United States Environmental Protection Agency |access-date=July 9, 2016}}</ref>

Various state agencies identify counties by different coding schemes. The [[Ohio Department of Taxation]] assigns [[Vehicle registration plates of Ohio#List of county numbers|consecutive numbers]] for the purpose of enumerating taxing districts.<ref name="ODT">{{cite web|title=Ohio Counties with County Number|location=Columbus, Ohio|date=June 25, 2020|accessdate=September 11, 2023|publisher=Ohio Department of Taxation|url=https://tax.ohio.gov/static/excise/Ohio%20County%20Listing.pdf}}</ref> The [[Ohio Department of Public Safety]], including the [[Ohio Bureau of Motor Vehicles]], associates these county numbers with vehicle registrations.<ref name="ODPS">{{cite book|title=Taxing District Code Book 2023|publisher=Ohio Bureau of Motor Vehicles, Tax Distribution Section|date=January 3, 2023|accessdate=September 12, 2023|url=https://publicsafety.ohio.gov/static/Taxing-District-Code-Book.pdf}}</ref> The [[Ohio Department of Transportation|Department of Transportation]] uses three-letter abbreviations in road inventory and traffic management applications.<ref name="ODOT">{{cite web|title=ODOT County Abbreviation Table|publisher=Ohio Department of Transportation|date=May 1, 2013|access-date=December 21, 2014|url=http://www.dot.state.oh.us/Divisions/Planning/TechServ/TIM/Documents/SLD/ODOT_County_Abbreviation_Table.pdf}}</ref> 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.<ref name="OHPO">{{cite news |title=Ohio Archaeological Inventory Form Instruction Manual |publisher=[[Ohio Historical Society|Ohio Historic Preservation Office]] |date=June 2003 |page=61|accessdate=September 12, 2023 |url=https://www.ohiohistory.org/wp-content/uploads/2022/01/OAI_Manual_rev_2003.pdf#page=61}}</ref>
