Martinsburg West Virginia ZIP Codes

Martinsburg holds 5 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We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP.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 Martinsburg codes above are listed without a column we would have to invent.
