ZIP code radius map

Search a ZIP, city or address to set the center, then pick a radius or drag the circle’s edge. Every ZIP whose center falls inside the circle lights up and is listed nearest first, with its distance and population. Copy the list or download the CSV.

A ZIP is counted when its center point is inside the radius, the same rule most radius tools use. Big rural ZIPs can poke out of the circle while still counting. Tap any ZIP on the map to add it or drop it by hand.

Yes. Use the mi / km switch next to the radius. The slider runs from half a mile to 200 miles, and the presets jump to the common sizes.

By default the list shows only ZIPs with a delivery area. Tick “Include PO Box and single-building ZIPs” to add the PO Box and single-building ZIPs inside the circle, which matters if you are mailing to businesses.

Use Share link. It saves the center and radius, so whoever opens it sees the same circle and the same ZIPs lit up.

The total adds up the population of every ZIP in the list, from the Census Bureau’s American Community Survey 2020–2024. Because whole ZIPs are counted, it is an estimate of the area, not an exact count inside the circle line.
