    Where to find and download the US zip code map ESRI shape file?

    I am trying to create an application by using US zip code map in Spotfire, but I couldn't find the shape file. Do you know where I can find it and get free download?

     Thanks

    there is no official shape file for zip codes. the postal service doesn't consider zip codes to be area data, but rather route data. also, they change from time to time.

    your best bet is the census bureau site, which has shape files for their approximation of the zip code boundaries. the latest ones are from 2000, hopefully your application doesn't need anything more recent than that:

    i spoke too soon. 2010 shape files for zip code boundaries may be found here on the census bureau web site:

    i haven't looked them over, but be forwarned that these particular shapefiles potentially have a *lot* of points and may benefit from a simplification algorithm if they're for display purposes only. some of the county and state boundaries that align on bodies of water definitely have this issue.
