Accuracy of Data
The USDA originally compiled this data in 2012, but from time to time the US Postal Service activates new zip codes. For the newer zip codes, I have extrapolated the zone from the nearest original data. The data contained in the 'distance' column is the extrapolation error (in miles). This should allow you to judge for yourself whether or not a particular zip / zone pair satisfies the requirements of your application.
