We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP.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 Essex codes above are listed without a column we would have to invent.
Scope every ZIP code recorded for Essex. 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 Essex ZIP code begins 609. Those first three digits identify the sectional center facility that processes mail for this part of Illinois. Statewide that range covers 57 ZIP codes, so Essex accounts for 2% of it.
