Hi,

I would like to know if your product provides different areas than the census zip code tabulation areas? The census files do not have a complete enough zip code listing for my purposes but if this product just wraps that data it is not helpful to me.

For an example of what I’m talking about you can see zip code 20500 on this map, http://maps.huge.info/zip.htm, and notice that the publicly available files do not include a polygon for that zipcode.

Thanks for your help!
