Modes of Delivery
Providing mail delivery is central to the Postal Service’s mission. Delivery is the Postal Service’s largest operational function and accounted for approximately one-third of its nearly $78 billion in total expenses during 2008. Postal Service management is working hard to reduce delivery costs while continuing to deliver to 149 million[1] addresses in the most efficient manner possible. Despite declining mail volumes, the Postal Service is challenged to provide cost efficient and effective service to a delivery network growing by more than 1 million addresses each year.
