Question

want to know all zip codes in usa

Answer 1

There's a massive book with all of them, in the post office, but you can't take it home. If you need to look up any given address's ZIP code, the web site http://zip4.usps.com/zip4/welcome.jsp will give you the full 9-digit ZIP+4 code, and show the address in preferred USPS format into the bargain.
