Preparing for Successful VDP

Neither CASS nor DPV does anything to verify that the person the mail piece is addressed to is still at that address. For residences you can run the address through the "National Change of Address" (NCOA) service, which looks at who lives at that address and validates the name to the address, but it does not work as well with businesses. A business can complete a change of address card for the USPS if the company moves to a new location, but an individual cannot fill out a change of address card if they change jobs and start working for another business. So you can lose a lot of these contacts in the business world.
