OpenStreetMap
I have now polygon files for the 5 digit zipcodes census tabulation areas
and am uploading them to archive.
http://fmtyewtk.blogspot.com/2009/12/shapfiles-for-nj-zcta-zip-code.html
The nice thing about these files is that they work just fine for the zip codes that I have looked out (long hill township 07933)
Using these polygons and the bounding boxes, we can split up the OSM file and
also check the tiger import. I found alot of missing zipcodes and even some that were wrong in the tiger import.
I will be creating OSM files from the NJ osm data from cloudmade next, so will spit the dump up by zipcode.
Also will be producing county polygons as well.
The code is now checked in, yes it is a hack, but it is a hack of a hack.

You can see the difference between the zcta and the "zip codes"
Here are the ztcas :

There are differences that you can see between the two versions.
I understand the panic better now.
But we have to start somewhere!
