Randall is a small farming community in Hamilton County, Iowa, about 13 miles north of Ames. With 157 residents and 69 households, it's a compact town where everyone knows their neighbors. This is a PO Box Only Zone, meaning the post office is the sole option for mail delivery. All 79 PO Boxes serve residents here and in the surrounding rural area.
The town's housing tells a story of longevity. Every one of the 77 housing units was built before 1939. These aren't vacation homes or weekend getaways; 85% of occupied homes are owner-occupied, and there's no seasonal vacancy. People live here year-round, and their families have done so for generations.
Randall's economy has an interesting profile. Over half the workforce (51 workers) is employed in transportation, warehousing, or utilities. That's unusually high for a town this size and likely ties to the agricultural logistics that keep Iowa running. Another 28% work from home. Median household income sits at $69,688, close to the state average.
Street names mix small-town character with rural Iowa's grid system. Main Street and Long Street run through the core, while numbered county roads like 380th Street and 375th Street connect to farms beyond town limits. The post office at this location has served Randall since before 2004, and for residents here, it's not just where you pick up mail. It's where you catch up with neighbors.
Mix of traditional small-town streets (Main, Long) and Iowa's numbered county road grid system (370th-385th).
