ZIP code 60434 serves downtown Joliet, Illinois, operating as a PO Box-only zone within the larger city. This isn't a separate community but rather a dedicated postal facility embedded in Will County's largest city. The ZIP has no residential population assigned to its boundaries because it exists as a point location, fully enclosed within neighboring ZIP 60436.
The post office maintains 702 PO Boxes and serves 329 business delivery points.
