Tool
ZIP Codes Within a Radius Enter a ZIP code and a distance. The tool lists every residential ZIP code whose center (the Census Bureau's internal point of its area) lies within that many miles, nearest first. PO Box and single-organization codes have no area of their own, so they are not placed.
