By the way, if you'd like to nab my code for calling the geocoder
service in CF, I've blogged it.

What do you mean, "the difference between the two?" Do you mean you'd
like to find the distance between the two zip codes? If so, I'd
recommend you check out geocoder.

http://geocoder.us/help/city_state_zip.shtml 

you can get the lat/lon for a zip, like this:
http://geocoder.us/service/csv/geocode?zip=75034

so if you get it for both zips and then calculate it with the great
circle equation, Robert's your father's brother.

Does anyone know a reliable site to lookup zip codes, more specifically
I want to look up the difference between two?
I googled and saw some, but didn't know how reliable they were.

Thanks,
Seth
