Coopers Mills operates as a PO Box facility serving far beyond its immediate footprint. With just 5 occupied households generating local mail demand, the post office maintains 79 PO Boxes. That's an adoption rate of 15.8—meaning the facility serves nearly 16 times as many boxes as local housing units. This level of disproportion signals a regional hub, not a neighborhood post office.
The numbers tell a specific story. Of 70 people counted in the 2020 Census, 47 live in institutionalized group quarters. That's 67% of the population. The ratio of 14 people per household confirms this isn't a conventional residential community. These patterns typically indicate a correctional facility, nursing home, or similar institution.
Mail delivery here follows building-based routing rather than residential carrier routes. The ZIP contains no city carrier routes for street delivery and operates as a pure PO Box zone. All mail flows through the post office at the single delivery point on Main Street. Residents in the surrounding area outside the facility rely on this post office as their primary mail hub, which explains the high box count relative to local housing.
Coopers Mills sits within Lincoln County at coordinates 44.317°N, 69.434°W. The Census designates this as a multipoint geometry rather than a bounded area, consistent with a facility-based ZIP code. For geographic reference, the nearest traditional neighborhoods are Bristol and Pemaquid, both roughly 18-20 miles away in the Damariscotta metro area. The median age of 65.5 years reflects the institutional population composition rather than a typical community age distribution.
The post office at Coopers Mills has served the area since before October 2004, when the current ZIP code system was formalized. It maintains 8 ZIP+4 records, including 6 for PO Box ranges and 2 for street delivery. This configuration supports both the institutional facility and the surrounding rural population that depends on PO Box service for reliable mail access.
With just one street record for Main Street, this ZIP code's delivery infrastructure centers entirely on the post office facility itself rather than a distributed residential network. The single-street pattern is consistent with an institutional facility where mail flows to a central point rather than individual addresses.
ZIP Code 04341 has 70 residents and 5 households (average 4.60 persons per household). The median age is 65.5 years, significantly older than the state (45.1) and significantly older than the nation (38.8). The gender split is 61.4% male and 38.6% female, which is much higher than the state male share (49.0%), making this a male-majority area. Largest groups are White (88.6%, much higher than the national average of 61.6%) and Hispanic or Latino (4.3%); Hispanic or Latino residents make up 4.3%, which is much lower than the national average (18.7%).
