Wow... melissadata may update their zips every quarter, but it looks like they need to do some serious work on the population figures. According to them it looks like Dallas has all of around a few hundered thousand residents. I always imagined the number would be so much higher than that (like around 1.25 million.)

I'll give him the benefit on the formula, it'd take too much thought for me to try & qualify that (lol cameron) All depends on how many store's you've got, and how "accurate" you're trying to be. Low fi solution, I'd recommend just stripping off the first 2 characters of the zip & adding up or down as many places as you want, then searching the range. Won't give you mileage data, but if you don't need that, its easier & cheaper (free) Ex: zip 75202 entered. strip 202, & search like %75 or like %74 or like %76... relatively useful tool for getting a textual idea of how zipcodes are laid out here: http://xml2.melissadata.com/LookUps/zipradius.asp i had a zip map of the us, but can't find it. Like i said, LO LO FI. on the other hand, as a developer you'll probably get asked for this a lot, so maybe invest in doing it right if you can get the client to pony up a couple hundred... then you can "resell" the "application" you developed time & time again... plus, you could put it on your personal website, so visitors could track your closest family member to their location.... : ) good luck... (actually, just read derek's post, sounds like you could use my search & his distance thing to get where you're going, if you don't want to buy the tag/db for 325) kyle >Find the closest store application... > >Working on a "find a store near you" type of application. > >Anyone have any tips on this sort of thing?
