About ZIP Code 16048

North Washington, Pennsylvania sits in Butler County with 168 residents spread across 0.75 square miles. The post office maintains 48 PO Boxes serving a mix of urban and rural delivery patterns. Street delivery reaches homes along Oneida Valley Road, Fairview Road, and several smaller lanes, while nine rural routes serve the surrounding countryside.

The adoption rate of 0.61 means that for every ten households in the area, about six maintain PO Boxes. That's higher than street-delivery-dominant areas but not unusual for a small community where rural routes and PO Boxes work together. Most residents have delivery options, but the mix of carrier routes suggests that PO Boxes remain practical for many. With a median household income of $57,500 and median home values around $112,500, this is a modest community where affordability matters.

Street Name Patterns

Valley Roads Directional Names

The street names reflect rural Pennsylvania geography, with 'valley' and directional references common in hilly western Pennsylvania terrain. Oneida Valley Road and Fairview Road carry most delivery points, while smaller lanes like Poganski serve individual properties.
