This application from CDX Technologies creates a radius report for a list of zip codes. Thousands of zip codes can be analyzed at one time. All US zip codes within the specified radius will be returned for each zip code specified.
As a first step, just upload an excel spreadsheet or csv file with a single column of zip codes as in this file example. This online tool will then create an output report based on this. The report will be in the same order as the input file. All zip codes within the specified radius will be returned in the same row. A count of the number of zip codes returned in each row will also be provided.
