Waldorf Maryland ZIP Codes

Waldorf holds 4 ZIP codes, all inside one county and one postal prefix.

We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP.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

Scope every ZIP code recorded for Waldorf. 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 Waldorf ZIP code begins 206. Those first three digits identify the sectional center facility that processes mail for this part of Maryland. Statewide that range covers 68 ZIP codes, so Waldorf accounts for 6% of it.
