>Does anyone have any experience with the USPS web services tool kit? It seems to be a free service for looking up correct US address and zip codes.


Yes, I had some code that worked for a while, but now returns 00000 when an address is passed. I think they may have gone to a pay format. I went ahead and subclassed IE and navigate to the page, populate it, click, then pull the data from the html page. It's a pain and much slower than a WS, but it works.
