Every ZIP code within a chosen radius of any point, with a CSV download.
How this tool works
Pick a center (a city, a ZIP code, or coordinates) and a radius. The tool measures the distance from the center to all 33,791 ZCTA center points from Census gazetteer data and lists every code inside the radius, nearest first. The full list can be downloaded as a CSV. Codes whose area partly overlaps the circle but whose center lies outside will not appear, so treat results near the edge accordingly.
What you can do with it
- Build ZIP code lists for mailing campaigns, service areas, and store catchments
- Feed the CSV straight into spreadsheets, CRMs, or ad platform targeting
- Check how many ZIP codes a given radius actually covers
- Center the search on a ZIP, a city, or exact coordinates
Why use it
Radius-based ZIP lists are a standard marketing and operations need that usually sits behind paid tools. The underlying data is public, and this does the whole job in your browser with a one-click export.
