For United States Addresses you take the user supplied address and pass it to the United States Postal Service to read the returned address then you take the results you received from the USPS and pass it to GeoCoder.us to get the Lat/Long of each Address.

In some places, a building has it's own zipcode. I also recommend you geocode each address, then do the distance math between lat-lons. Google it and you'll find several formulas. There are several address geocoders to use on the cheap, but you get what you pay for (daily limits, unresolved addresses, etc.) If you have some budget, check out www.proxix.com. > > Paul C > > ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Get the answers you are looking for on the ColdFusion Labs Forum direct from active programmers and developers. http://www.adobe.com/cfusion/webforums/forum/categories.cfm?forumid-72&catid=648 Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:294162 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
