Farmer is a crossroads settlement in Defiance County, Ohio, where State Routes 2 and 249 meet. With just 77 residents in 31 households, it's one of the smallest communities with its own ZIP code in Ohio. This is a PO Box Only Zone, meaning there's no alternative mail delivery anywhere in the area. Everyone here relies on the Farmer post office.
The post office maintains 16 PO Boxes for the 31 local households, a 52% adoption rate. The remaining residents receive mail through the enclosing ZIP code 43506 (Bryan), but those who want a Farmer mailing address need a box. There are no city carrier routes originating from this ZIP. The community sits within Bryan's postal territory as a point location rather than having its own defined service area.
Farmer skews older. The median age is 54.5 years, with only 3 children under 18 and 4 young adults aged 18-24. Housing tells a similar story: about 35% of homes (11 of 31) were built before 1939. Half of the households own their homes, half rent. Nobody moved in looking for new construction.
The street addresses here are highway-based: State Route 2 and State Route 249. There are no named residential streets, no subdivisions, no apartment complexes. Three businesses operate here, but there's no data on employment since the population is too small for reliable estimates. This is rural northwest Ohio at its most elemental.
All addresses are on state highways at this rural crossroads, with no named residential streets.
