  • http://www.semaphorecorp.com/cgi/form.html Wow! Doesn't show the County but does give the fips code. Returns usefull information no matter how little data you supply. For example, given a city and state, it shows the zip code range that could apply.

• http://www.usps.com/ncsc/lookups/lookup_zip+4.html For addresses inside the USA, you can enter an address, get the full ZIP+4 code back and the address reformatted exactly the way the U.S. Post office likes it. On June 17th they changed it from .gov to .com and the one at .gov still responds but with an error message that leads one to believe the request was mal-formed.

  The new Zip+4 lookup page at http://www.usps.com/zip4/welcome.htm contains a note saying "For integrating ZIP Code Lookup capabilities into your web site or application system, please visit our Web Tools (APIs) or find additional addressing products at Address Information System Products (AIS)."

  However, as far as I can see, there is no zip code lookup or address verificatoin tools in the in Web Tools and the AIS products are databases that are updated by subscription and have a starting cost around $1000.00. Just scrape the page.
