Boise Idaho ZIP Codes

Boise holds 28 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We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP.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 Boise codes above are listed without a column we would have to invent.

Scope every ZIP code recorded for Boise. 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 Boise ZIP code begins 837. Those first three digits identify the sectional center facility that processes mail for this part of Idaho. Statewide that range covers 29 ZIP codes, so Boise accounts for 97% of it.

ZIP codes and area codes are separate systems — one routes mail, the other routes calls — and they do not share boundaries. The codes below serve the same ground Boise occupies.
