The USPS offers discounts for depositing Carrier Route mail at the facility responsible for delivery to the final destination of those pieces. The term used to describe this facility is Post Office of Entry, or POE.

However, additional discounts may be available for depositing mail at other facilities responsible for delivery of your mail other than your POE. In addition to lower rates, delivery time is often greatly improved when this is done.

The term used for these additional entry points is Destination Delivery Unit, or DDU.
