Millington Maryland ZIP Codes

Millington holds a single ZIP code.

We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP.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

Scope every ZIP code recorded for Millington. 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.

Every Millington ZIP code begins 216. Those first three digits identify the sectional center facility that processes mail for this part of Maryland. Statewide that range covers 62 ZIP codes, so Millington accounts for 2% of it.
