Dudley is a small rural community in Huntingdon County, Pennsylvania, with 283 residents spread across 4.4 square miles. This is a PO Box Only Zone. There's no alternative mail delivery available anywhere in the territory. The Dudley post office maintains 119 PO Boxes for the community's 122 occupied homes, giving this ZIP one of the highest adoption rates in Pennsylvania at 97.5%.
Mail reaches Dudley through a single rural carrier route that serves 64 street addresses. That's unusual for a PO Box classification. Most Classified as a PO Box ZIPs either have no street delivery at all or extensive carrier infrastructure. Dudley sits in between. Streets like Broad Top Mountain Road (16 delivery points), Washington Street (6 points), and numbered streets (2nd, 4th, 5th) form the backbone of the small town grid.
This is an established working-class community. Of the 122 occupied housing units, 106 are owner-occupied (87%). Median home values sit at $91,300. Median household income is $58,571. The median age is 48.1 years, indicating an older, settled population. Only 5 residents are under 18. Educational attainment runs low, with just 9.7% of adults holding bachelor's degrees.
The economy centers on transportation and warehousing. Of the community's workforce, 83 people work in transportation, warehousing, or utilities. That's a remarkable concentration for such a small population. Another 35 work in educational services or health care. Work-from-home is common here: 42.7% of workers (5 people) work remotely. The ZIP supports 5 business establishments employing 13 people total, plus 7 business delivery points.
Dudley's location in the Broad Top Mountain region of central Pennsylvania explains the PO Box dependency. The terrain is rugged, the population sparse, and development scattered. Nearby communities include Fort Littleton (8 miles away), Burnt Cabins (12 miles), and Hustontown (17 miles). The ZIP includes 152 total housing units, but 30 remain vacant. Of those vacant units, 11 are seasonal or recreational properties, likely hunting cabins or weekend retreats in the mountains.
All mail to Dudley addresses should use PO Box format:
