mdillon helped with your POST problem.
Have you thought about using Data::Address::Standardize to get the zip codes? I used it for a large mailing I did for a fund raiser - worked quite well with partial addresses and so forth.

Update: ehdonhon points out that D::A::S is deprecated! Been a while since I used it, but id did it's job nicely. Partial addresses magically became complete, wrong addresses became right.
