Vancouver, WA

ZIP code 98666 is a PO Box–only postal ZIP associated with Vancouver, Washington, rather than a conventional neighborhood with a defined residential footprint. Consequently, it has no reliably assignable set of physical landmarks within its boundaries. Well-known Vancouver sites—including Fort Vancouver National Historic Site, Pearson Field, and the Vancouver Waterfront—are nearby, but lie in other ZIP-code areas and should not be described as located in 98666.
