The post office developed two types of computer programs that help to stay in line with the ever-changing lifestyle of the people in the United States as 17% of its citizens move annually. These programs include:
Address Management System (AMS): This program places barcodes on all your emails, which indicates the delivery location. A file with these barcodes is with the post office so that they are certain there is no mix up with the addresses given to them.
Computerized Forwarding System (CFS): This program is in charge of having your mail forwarded to your new address. It takes care of all corrected addresses in the database. A sticker will be attached to your mail, which indicates that it was forwarded by the post office.
