How it works

Distances are straight-line from the centre ZIP's coordinates, sorted nearest first, up to 124 miles (200 km) and 100 results per search — narrow the radius for a complete list in dense metros. Every code links to its full page with demographics, time zone and area codes.

The CSV download gives you code, place, miles, km — ready for mailing lists, service-area definitions or spreadsheets. For bulk or automated use, this exact search is GET /v1/nearby on the free CodePostalPro API, also available to AI assistants via our MCP server.
