This program uses a database of US Zipcodes, to calculate "crow flight" distance between zipcodes. Database currently has 42,210 zipcodes. NOW including Guam, Micronesia, Marshal Is.,Puerto Rico and the Virgin Islands. Lookup
Notes: Since the earth isn't quite round, I have to tell you right
off, "your mileage may vary". And while 42,210 cities may
sound like a lot, theres quite a few holes in the data. If you know of a source for a complete Zipcode database, containing city, state, latitude, and longitude, please use the Contact button on the main page.
