This isn't a true PO Box-only zone despite the 06373 ZIP containing no street addresses. Residents receive mail through two rural carrier routes that cover 1.86 square miles of mixed woodland and residential properties. Plainfield Pike and Newport Road are the main arteries, with Deerfield Shores and several smaller roads branching off toward scattered homes.
