Answer 1

Thanks Guys,

I got all the the countries and states of all of them, but no zip codes.

http://27.org/isocountrylist/iso_country_list.sql

This contains all countries, and there iso-3166 codes ( Siberia code needs to be changed from "CS" to "RS")

And here is the FIPS file for countries with states

For zip code validation I am using

http://www.geonames.org webservices

There is a geonames ruby gem as well, which makes it really simple to do zipcode validations

Hope that helps anybody who needs this information, worth keeping it handy for web projects.
