One of our students came across some address matching programs while doing
census research in the Hartford, CT area from the U.S. Postal Service. Is
anyone else aware of this program? Is it available for "all?" metro areas?
And from whom? Also, a main problem we are having is for the contiguous
suburban areas which the Post Office seems to have not included. Also,
interesting enough, we have discovered that MapExpert does include a sizeable
amount of "block number" matching which has proved valuable.
 
Any information in this area would be greatly appreciated.
