San Diego city ZIP-code catalogue

Find residential postal anchors, institutional codes and boundary-overlap candidates. Verify the street address before treating a ZIP as city territory.

ZIP codes are postal identifiers, not municipal boundaries. This catalogue helps orient your search; confirm your street address is inside the City of San Diego before arranging service. SanGIS polygons are approximate and omit PO-box and some special-use codes.

Use your actual street address

A postal community named San Diego does not establish municipal jurisdiction; equally, a ZIP associated with another community may touch an isolated city parcel. Institutional and military ZIPs require special attention and are not ordinary residential service territory.

Method and sources

Checked 12 October 2026. Official City boundary polygons were intersected with approximate SanGIS geographic ZIP polygons. Positive-area overlaps include uncertain slivers; they are retained as boundary candidates, not promoted to residential coverage. The core residential anchors are separated from institutional/military and boundary candidates. This is not a claim to list every USPS PO-box ZIP.
