We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP. USPS delivery-type products are licensed, and no clean-rights source maps ZIP codes to neighbourhoods — so the Louisville codes above are listed without a column we would have to invent.

Scope every ZIP code recorded for Louisville. Source GeoNames US postal codes (2026-07 postal dump) and Census 2024 county Gazetteer (2024 Gazetteer). Updated . ZIP codes are delivery-route groupings, not areas; the boundaries implied by any ZIP map are approximations.

How these codes cluster

Every Louisville ZIP code begins 402. Those first three digits identify the sectional center facility that processes mail for this part of Kentucky. No other Kentucky community draws on the 402xx range — it belongs entirely to Louisville.
