The 163 residents who call 48190 home live across 1.12 square miles of rural Washtenaw County. Mail arrives via two rural carrier routes, serving just four streets: Whittaker Road (the main route with three ZIP+4 records), Talladay Road, Spanish Oak Lane, and Laurel Oak Lane. There's no city carrier service here. The rural delivery infrastructure handles local needs, but the PO Box operation clearly extends well beyond Whittaker's borders.
This isn't a struggling community relying on PO Boxes by necessity. The median household income sits at $74,732, well above many rural areas. Median home values reach $219,600. These figures suggest a stable, middle-income population that's chosen PO Boxes alongside the available rural delivery. The median age of 38.8 years indicates a mix of working families rather than retirees or students.
The facility also serves 13 businesses, maintaining a named building entry for the Postmaster. Seventeen distinct ZIP+4 codes organize the delivery area: seven for street addresses, ten for PO Box ranges. That PO Box infrastructure supports not just Whittaker residents but customers from the broader region who need reliable mail service in an area where street delivery doesn't reach every home.
The street network is minimal, with Whittaker Road as the primary route and newer development evident in the oak-themed lane names (Spanish Oak, Laurel Oak). This limited street infrastructure contrasts sharply with the extensive PO Box operation serving the broader region.
ZIP Code 48190 has 163 residents and 68 households (average 2.40 persons per household). The median age is 38.8 years, slightly younger than the state (40.1) and about the same as the nation (38.8). The gender split is 44.8% male and 55.2% female, which is lower than the state male share (49.3%), making this a female-majority area. Largest groups are White (91.4%, much higher than the state average of 73.9% and well above the national average of 61.6%) and Hispanic or Latino (3.1%); Hispanic or Latino residents make up 3.1%, which is much lower than the national average (18.7%).
