[1] As of 2024[update], plates are issued by the Tennessee Department of Revenue through its Vehicle Services Division.

In 1956, the United States, Canada, and Mexico came to an agreement with the American Association of Motor Vehicle Administrators, the Automobile Manufacturers Association and the National Safety Council that standardized the size for license plates for vehicles (except those for motorcycles) at 6 inches (15 cm) in height by 12 inches (30 cm) in width, with standardized mounting holes.

From 1939 through 1965 and from 1971 through 1988, Tennessee license plates began with a one- or two-digit county code.

Beginning March 4, 2015,[20] Tennesseans were granted the ability to purchase gift vouchers to buy state specialty plates for relatives and friends.

This program is no longer available, but vouchers previously purchased can be redeemed at county clerk offices.
