The post office handles mail for 112 business customers alongside residential box holders. This setup is common in Michigan downtowns where a central post office maintains PO Box service while neighboring carrier routes deliver to street addresses. The facility sits in the heart of Pontiac's metro area, part of the greater Detroit region, where urban postal patterns blend PO Box convenience with standard city delivery options.
Street records are minimal, with W Huron Street representing the primary documented delivery route. The single-street pattern reflects this ZIP's role as a PO Box facility rather than a full-service delivery zone—most street addresses in this area use the enclosing ZIP code 48342.
