South Dennis isn't quite a traditional town. With just 35 residents and 17 occupied households, it operates primarily as a PO Box ZIP serving the surrounding area. The local post office maintains 56 PO Boxes for a population that could theoretically fit in a small apartment building, creating an adoption rate of 3.29—meaning the facility serves more than three times the local household count. This reflects its role as a regional postal hub for nearby communities without dedicated carrier delivery.
The demographic profile suggests a quiet retirement community. The median age of 51.2 years and small household size of 2.06 people indicate established couples or individuals in later life stages. All 17 households are owner-occupied, and the community has access to limited street delivery through County Road and Route 47 Road. Two city carrier routes and one rural route serve the broader delivery area, though the ZIP itself is classified for PO Box service only. The post office building, referenced in postal records simply as "Postmaster," anchors this small Cape May County settlement near the southern New Jersey shore.
The street names reflect a rural infrastructure pattern with county-maintained roads and state route designations rather than traditional street grids. County Road handles most delivery points, while Route 47 Road provides the secondary connection. This naming system is typical of sparsely populated areas where roads follow property boundaries and regional corridors rather than planned subdivision layouts.
ZIP Code 08245 has 35 residents and 17 households (average 2.06 persons per household). The median age is 51.2 years, significantly older than the state (39.9) and significantly older than the nation (38.8). The gender split is 20.0% male and 80.0% female, which is much lower than the national male share (49.1%), making this a female-majority area. Largest groups are White (97.1%, much higher than the state average of 55.0% and well above the national average of 61.6%) and Hispanic or Latino (5.7%); Hispanic or Latino residents make up 5.7%, which is much lower than the state average (21.6%).
