This is a true PO Box Only zone, meaning residents don't have alternative carrier delivery available. Rural carrier routes serve the surrounding area, but the post office itself operates exclusively with PO Boxes. The adoption rate of 0.798 suggests that most households use boxes for local pickup rather than relying on broader regional service.
With only one street in the ZIP+4 database, Codorus operates primarily as a PO Box facility rather than a street-delivery community. Baltimore Street represents the minimal street presence in postal records.
