I tried searching for something similar months ago. I couldn't find 
anything that didn't require a payment per zip code. I was going to 
suggest looking at the new google maps api and see if that offered what 
you needed, but they don't include that yet.

The USPS who defines these boundries might be able to help:

I also came across this url fairly quickly:

Keep in mind the note found here:

The fact that ZIP Codes aren't required to be polygons makes them 
difficult to map.

That would also make them hard to put into a csv file.
