Yes you could use Google Maps API for this, but if you already have zip code info from any of the hundreds of vendors (or even from USPS), they will/should have the geocodes (lat/long) for each postal code. Then it is relatively simple math to calculate the distance. Search for .net calculate distance and see a number of examples like at http://blog.wekeroad.com/2007/08/30/linq-and-geocoding/
Hope this helps.
