- This is kinda of easy if you have the right data. If you have access to the US
- POSTAL database. They give you the longitude/latitude for every zip code then
- it is very easy to compute the distance, if you have access to the TIGER/+4
- database, also available from the US Postal service, you could compute the
- distances from Plus+4 zips.
-
- The following company has zipzip a program that you could use to determine
- distances between Zip codes, not Zip plus for. You have to do extra work to
- find the distance between Zip+4. I have done it, if you like I can tell you
- how I did it.
