I've seen many sites that let you enter your zip code in a search field and return results based on zip codes that surround yours (i.e. find a u-haul or Starbucks store locator). I want to do something like this on a site of mine (without the groovy maps) but couldn't figure out how this is done.

I originally thought to find zip codes within a few numbers of the one entered, but zip codes don't seem to be in any specific numeric order (i.e. 19087 is adjacent to 19406). Has anyone ever done this before?
