College Springs sits in the southwest corner of Iowa, just 1.3 square miles along the Missouri border in Page County. With 173 residents spread across 78 households, it's a quiet rural community where the median age of 51.5 years reflects an older, established population. Nearly everyone owns their home. Of the 80 total housing units, 71 are owner-occupied and just 7 are rentals.
This is a PO Box Only Zone. There's no alternative mail delivery option anywhere in the area. The post office maintains 86 PO Boxes serving the 78 local households plus surrounding rural addresses. That 1.10 adoption rate means the College Springs post office serves more than just the immediate village, reaching residents from the broader countryside who travel here for mail access.
Mail arrives by rural carrier route, covering 69 delivery points across streets named Iowa Avenue (13 addresses), Missouri Avenue (9 addresses), and smaller lanes like Spruce Street and Spring Street. Street names honor neighboring states and suggest the town's location at Iowa's western edge. Despite the rural carrier route designation, residents receive mail through PO Boxes rather than roadside delivery, which is typical for small Iowa communities without street addressing infrastructure.
The village shows modest economic characteristics. Median household income stands at $70,323, with a median home value of $73,500. About 31% of workers commute from home, a high rate that likely includes agricultural work and remote employment. The Census reports 33 agricultural workers and 98 transportation/warehousing workers, suggesting farming and trucking sustain the local economy. Educational attainment is lower than state averages, with just 22% holding bachelor's degrees.
All mail must be addressed to a PO Box:
