Nachusa is a tiny unincorporated community in Lee County, Illinois, about 80 miles west of Chicago. With just 108 residents and 46 households, it's one of the smallest communities in the state with its own ZIP code. This is a PO Box Only Zone. There's no street delivery alternative anywhere in the area, so the post office and its 17 PO Boxes serve as the only mail access point for local residents.
The community sits on barely more than a few acres. Warren Street and Market Street are the only named roads in the ZIP+4 database. Nearly all housing is owner-occupied (93%), and much of it dates back generations. Of the 52 housing units, 23 were built before 1939. That's 44% of the housing stock constructed over 85 years ago.
Nachusa isn't a retirement community, a resort, or a bedroom suburb. It's an old rural hamlet where families have stayed put. The median age is 41.5 years. All residents were born in the United States.
The post office, operating under facility code P (Post Office), has been serving this community since before USPS tracking began in 2004. Rural routes R001 and R002 handle what limited carrier delivery exists, but for most residents the PO Box is how mail arrives.
Just two streets appear in postal records, reflecting the hamlet's minimal footprint.
ZIP Code 61057 has 108 residents and 46 households (average 2.35 persons per household). The median age is 41.5 years, slightly older than the state (38.8) and slightly older than the nation (38.8). The gender split is 46.3% male and 53.7% female, which is slightly lower than the national male share (49.1%), making this a female-majority area. Largest groups are White (92.6%, much higher than the state average of 61.4% and well above the national average of 61.6%) and Hispanic or Latino (4.6%); Hispanic or Latino residents make up 4.6%, which is much lower than the national average (18.7%).
