Zip codes within a radius

Find every zip code within a set distance of any U.S. zip code. Distances run in a straight line from the center of your zip code to the center of each nearby zip, and the results list each zip's city, state, population and median household income from the Census Bureau's American Community Survey. Use it to define a delivery or service area, size up a local market, or plan a mailing, then download the full list as a CSV.
