zip codes

[Shailen]

Thanks Martin and Aahz. Anyone know if zip code information is
copyrighted for the US? Anyone can look up zip codes on usps.gov (and
other locations),so the information is readily available. I need zip
codes for a handful of cities and could map those myself (or write a
script to scrape them for me), but am not sure if they *MUST* be
purchased for copyright reasons. Anyone know?
