The Postal Service moves mail using planes, trains, trucks, cars, boats, ferries, helicopters, bicycles, hovercrafts, subways and even mules. It operates the largest civilian vehicle fleet in the world with more than 219,000 vehicles. Its fleet of trucks drives nearly 4.1 million miles and uses more than 400,000 gallons of fuel daily. To put this in perspective, when fuel costs increase by one penny, the cost to the Postal Service increases by more than $8 million annually.
In 1970, the Postal Service delivered fewer than 85 billion pieces of mail. Thirty years later, mail volume had more than doubled to nearly 208 billion pieces of mail — average growth of about 3 percent per year. The Postal Service relied upon this dependable growth in mail volume to finance the expansion of its network. The traditional business model worked.
USPS Mail Transport Equipment (MTE) consists of specialized containers such as sacks, pouches, trays, hampers, over-the-road containers and pallets. The Postal Service has more than 1.1 billion pieces of MTE, which is used at close to 400 processing facilities, over 33,000 post offices and hundreds of major mailers nationwide to help achieve the safe, secure and timely movement of mail between Postal Service facilities and its customers or contractors.
