We often get asked how to run radius calculations in bulk. For instance, if you'd like to know all ZIP Codes within a 10 mile radius of a list of ZIP Codes. This information can be used in performing a nearest store report, optimizing a mailing list or other applications. We've previously covered techniques for this as described in the blog post Get Radius Information for a List of ZIP Codes.
To help automate this further we've created a new template to manage the creation of these lists. The free template is available to CDXZipStream users on our website who have the Lite Version of CDXZipStream or better.
Just enter your ZIP Code list in column B. You can use the CDXZipList right-click function to generate a list of zip codes by city, state or county for this input. Use the option to only return the zip code column.
Then specify a radius distance and press "Calculate". Beginning in Column C, all ZIP Codes within that radius will be shown in individual cells. A radius distance up to 200 miles can be specified. You can also choose to return both the zip code and distance by clicking the check box on the right of the screen. Options to use the U.S. or Canadian databases are also available.
