Seattle, WA

ZIP code 98111 is a non-geographic, PO-box-only postal code associated with Seattle, rather than a neighborhood with defined streets or boundaries. For that reason, landmarks cannot be reliably identified as being “located in” 98111. Seattle’s best-known attractions—including Pike Place Market, the Seattle Art Museum, and the Seattle Aquarium—are in nearby downtown ZIP codes, not properly attributable to 98111 itself.
