The US Post Office really uses mules to deliver items to the Havasupai Indians, who live at the bottom of the Grand Canyon in Arizona. A train of mules is used to transport mail, along with food, supplies, and even furniture, down an 8 mile (12.87 km) trail to the base of the Grand Canyon. The daily deliveries to the Havasupai Indians weigh around 4,000 pounds (1814.37 kg), with an individual mule being able to carry 130 pounds (58.97 kg) at a time. The nearest Post Office location to the Havasupai Indians is in Peach Springs, Arizona and contains walk-in freezers to hold the food for delivery.

- The Post Office Stamp Fulfillment Center in Kansas City, Missouri is actually located 150 feet (45.72 m) underground in order to provide the right moisture levels for preserving the stamps.
- Ships on the Detroit River in Michigan have their own mail boat that delivers to them on the water, and it even has its own zip code.
