Mail hauling jobs include positions like a hub to hub driver and mail distribution clerk. In this field, you may haul a load of mail between postal facilities and pickup sites, manage mail carts at sorting facilities, drive, load, and unload a tractor-trailer, operate a mail sorter, or resolve issues with postage or carriers. You can do mail hauling on local or long-distance routes, and you usually focus on high-volume batches of mail. While many of these jobs are with the USPS, you can also find work as an independent contractor and with a private business that sends or receives significant amounts of physical mail.
