We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP.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 Madison codes above are listed without a column we would have to invent.

Scope every ZIP code recorded for Madison. Source GeoNames US postal codes (2026-07 postal dump) and Census 2024 county Gazetteer (2024 Gazetteer). Updated 15 July 2026. ZIP codes are delivery-route groupings, not areas; the boundaries implied by any ZIP map are approximations.

How these codes cluster

Every Madison ZIP code begins 064. Those first three digits identify the sectional center facility that processes mail for this part of Connecticut. Statewide that range covers 64 ZIP codes, so Madison accounts for 2% of it.
