address parser

I need a mailing address parser. I am not sure of the way to do it best. I can't find a white page book that will just list the addresses. I basically need something that will search/pull all the addresses for requirements that I put in. State, Zip code, county, etc. I also need it to verify the address with the usps so that I don't waste money on dead addresses or wrong ones. Again I am not sure how to do this, but I just need to be able to get lead lists for mailers.
