Westland is a small unincorporated community in Washington County, Pennsylvania, about 25 miles southwest of Pittsburgh. With 82 residents in 38 households, it's one of the smallest populated ZIP codes in the state. The post office maintains 60 PO Boxes for those 38 local households and serves surrounding areas without their own mail infrastructure.
This is a PO Box Only Zone. There's no alternative mail delivery across the community. While some carrier routes exist (one city route and one rural route serve 18 street addresses), the majority of residents rely on PO Boxes. The 1.58 adoption rate (60 boxes for 38 households) means the post office serves not just Westland proper but nearby rural addresses that share the ZIP.
Westland's street grid shows a typical small Pennsylvania town layout. Numbered streets (1st through 4th) cross with Penn Street and nature-themed lanes like Meadow, Oak, Dogwood, and Shady. Westland Road and Hornhead Road are the main through routes. The compact 0.17 square mile footprint contains 49 housing units, with 32 owner-occupied homes. Eight houses date to before 1939, giving the community a long-established character.
The median age of 47.5 years indicates a settled, middle-aged population. Most residents are white (62 of 82), with smaller Black (12) and Hispanic (14) populations. The Census reports zero business establishments, so residents commute elsewhere for work. Only one child under 18 lives here. It's a quiet residential pocket in Washington County's rural landscape.
