Street Address Verification and Information

Reverse Look-Ups, Address Verification, Zip +4 and other address information.

There are many reverse address directories online, below are the best I have found. If you know of a high quality address site (must offer free access, and not just another commercial online phone book) please submit it to suggestion@publicdatacenter for consideration.

MelissaDATA - Enter as much of the address as you have available and the search provides a great deal of available information.
