Aug 29, 2012 at 19:58 comment added devuxer I appreciate your research, but I disagree with your conclusion. As a user, I feel better when sites allow me to enter my Zip+4 because it provides an extra level of error checking. If I made a typo entering the address, the Zip+4 acts as an extra check to make sure my important package arrives at the right place at the right time. Even if I'm completely wrong about this, and the Zip+4 is just ignored, I still feel better as a user, and I think that alone makes it worth having an optional +4 when entering a zip code.
