With about 206,000 vehicles, the U.S. Postal Service’s fleet is one of the largest in the country. It takes a lot of fuel, oil, and maintenance to keep everything running.
To that end, the Postal Service provides a Voyager fleet card for each postal-owned vehicle to pay for fuel, maintenance, and repairs up to $300. In addition, USPS issues fleet specialty cards, which include four types of cards used for very specific purposes. For example, sites can use Z Cards for repairs to vehicles that exceed the $300 limit, and V Cards are used for fueling and maintaining leased vehicles.
