Westphalia is a compact rural community in Shelby County, Iowa, covering just 0.07 square miles. With 116 residents and 55 households, this is one of Iowa's smallest incorporated towns. Despite its PO Box classification in USPS records, most residents receive mail via rural route delivery rather than post office boxes.
The community post office maintains only 2 PO Boxes for 55 households, producing an adoption rate of just 3.6%. This extremely low rate shows that rural carrier delivery dominates the town's postal service. One rural route (Route R) handles 28 ZIP+4 records, delivering to streets like Duren Street (8 addresses), Colony Street (4 addresses), and Weber Street (3 addresses). The numbered grid (1st through 5th Streets) indicates an established town layout, though the entire territory is less than one-tenth of a square mile.
Westphalia's 116 residents have a median age of 47.3 years and median household income of $108,646, well above the national median. This isn't a struggling rural community. Of the 55 housing units, all are occupied with no seasonal vacancies. The homeownership rate is 69% (38 owner-occupied units versus 17 rentals). With 17% of workers working from home and median home values at $94,500, Westphalia offers affordable housing for remote workers and established residents.
The town's German Catholic heritage is evident in its name. Westphalia refers to the region in Germany from which many early settlers emigrated. The street grid and community post office reflect a traditional Midwestern small town established in the late 19th century. Four business establishments employ 13 people locally, though many residents commute to surrounding areas for work. Nearly all residents (99.3%) were born in the United States, and the population is 97% White.
Most addresses in Westphalia receive rural route delivery. Standard street addressing is available for residential mail. The community post office (Facility Code C) does not offer city carrier delivery, relying instead on rural carrier service for the small geographic territory.
Street names combine numbered grid pattern (1st-5th Streets) with German surnames (Duren, Weber, Flusche) reflecting the town's immigrant heritage.
ZIP Code 51578 has 116 residents and 55 households (average 2.11 persons per household).
