Millsboro sits along the Monongahela River in Washington County, Pennsylvania. It's a small community of 250 residents in 91 households, but the post office maintains 185 PO Boxes. That's more than twice the number of local homes. This is a PO Box Only Zone, meaning there's no alternative mail delivery for anyone in the area.
The town's history shows in its street names. Mill Street, Ferry Avenue, and River Street point to its origins as a river crossing and mill site. Monongahela Avenue runs through the community, named for the river that shaped it. Nearly half the housing stock (59 of 122 units) was built before 1939, and the town still includes 18 mobile homes.
With a median household income of $33,264 and a median age of 36.8 years, Millsboro is a working-class community. Most residents own their homes (75 of 91 occupied units). The employment pattern shows workers spread across transportation, public administration, and other services. Eighteen residents use public transit for commuting.
The post office functions as a regional mail hub for surrounding rural areas. People from beyond the ZCTA boundary drive to Millsboro for their mail because carrier delivery doesn't reach them. The nearest communities with recognized neighborhoods are Clairton (19 miles north in the Pittsburgh metro) and Cheat Lake (19 miles south in Morgantown, WV).
Street names reflect Millsboro's origins as a Monongahela River mill town and ferry crossing.
