Community Overview

South Colby is a small waterfront community on the Kitsap Peninsula in Washington State.

Postal Services

The post office maintains 334 PO Boxes and serves 56 local businesses. It's a compact operation. Only one street appears in postal records: SE Southworth Drive, which runs near the ferry landing that connects to Vashon Island and, via Vashon, to West Seattle.

Why Census Data Is Missing

Because this ZIP doesn't have its own Census boundary, population statistics aren't available. The zero-population figure in databases reflects the lack of a ZIP Code Tabulation Area, not an empty community. People do live here. They pick up their mail at the South Colby post office, board the ferry for Seattle-area jobs, and return to wooded lots overlooking the water.

Geographic Context

Nearby communities include Vashon (2.3 miles by water) and neighborhoods on Bainbridge Island's south shore, about 3.6 miles away. This corner of Kitsap County feels rural despite its proximity to Seattle. The ferry makes the difference: a 35-minute boat ride puts commuters in downtown Seattle, making South Colby a quiet bedroom community with an urban connection.
