[UW-GIS-L] ZIP code boundaries

[Phil Hurvitz]

Does anyone on the list have recommendations for sources (including 
prices if applicable) of up-to-date ZIP code boundary polygon data? The 
data sets on the ESRI data set media tend to be out of date.

Also, I'm specifically referring to ZIP codes, not the freely available 
ZCTAs from the Census Bureau.

Thanks for any suggestions.
