Ohio's oldest towns
51 towns researched so far, covering 83 of 1,233 Ohio ZIP codes.
Ohio's towns were not settled all at once. The state's first permanent Euro-American settlement, Marietta, was founded in 1788 at the mouth of the Muskingum River; Gallipolis and Cincinnati followed within a few years, and the rest of the state filled in west and north over the next century, township by township, as land offices opened and roads and canals reached further.
This ranks the 25 places on this site with the earliest founding, platting or incorporation date on record, oldest first. The list only includes places whose local history has been researched so far. That work proceeds county by county, starting from Franklin County and moving outward, so a place's absence here means its history has not been reached yet, not that it lacks one.

How this was measured
Colors each ZIP by the year the place most of its residents live in was first settled or platted, and the History card tells that place's story: the Native nations and sites recorded there and in its county, how the town began and got its name, a dated timeline, stories, photographs and the county's own history, with a statewide note on Ohio's peoples, earthworks and treaties. The research runs county by county outward from Franklin County; Sonnet and Opus research agents write one file per municipality and township from Wikipedia, the 1880s county histories on archive.org, Ohio History Connection, National Register listings, Ohio historical markers and local historical societies, and every claim carries the page it came from. Photographs are public domain or Creative Commons, each with its credit and licence. The files load on demand, so the card takes a moment the first time a county is opened.
Each town appears once, with the ZIP codes it covers; a town's year is the earliest of its settlement, platting or incorporation dates on record. Only towns whose local history has been researched carry a year, and the research proceeds county by county from Franklin County outward, so the list grows with every build.
83 of 1,233 ZIP codes have a figure; ZIP codes without one are left off the list, not counted as zero. Ties are broken by ZIP code.
Every ZIP code's own page carries the full detail behind its figure, and the Local history topic page ranks the whole state.
