Elco is a small village in Washington County, Pennsylvania, with just 246 residents and 107 households spread across 0.22 square miles. This is a PO Box Only Zone, meaning there's no alternative mail delivery despite the presence of street routes. The post office maintains 124 PO Boxes, slightly more than the number of households, indicating the ZIP serves some surrounding rural areas beyond the village itself.
The village shows a classic small-town Pennsylvania street grid with numbered avenues (1st Ave, 2nd Ave, 3rd Ave) intersecting named streets like High St, Jobes St, and Railroad St. The presence of Railroad St points to the area's industrial past, common in southwestern Pennsylvania coal and rail communities. Route 88 runs through the area, connecting to the broader regional road network.
Mail reaches Elco through a mixed delivery system. One rural carrier route serves 40 ZIP+4 records while one city carrier route handles a single address. General delivery is also available. Despite this street delivery infrastructure, the PO Box Only Zone designation means PO Boxes remain the primary method for residents to receive mail.
With a median age of 46.6 years and a median household income of $66,667, Elco is an established community. Most residents own their homes (84 of 107 occupied units). About 31% of workers work from home, higher than typical for rural Pennsylvania. The population is 92% white with a small Hispanic population of 30 residents (12%).
