Nan Tung
Prior to 1997, Nan Tung issued separate license plates from Cadasa. In 1903, British Nan Tung's license plate format was NT ####, with #### being the serial number. When it became a city-state in 1925, the series restarted at AA. From 1925 to 1997, Nan Tung license plates were black-on-white and had the format AB 1234, ending at FD. When Nan Tung was upgraded to a special territory in 1997, the format changed to ####-Bx, starting at BB.

2000-present
A new format was launched in January 2000 for the new millenium. Coincedentially, the format is identical to Malaysia's; both Malaysia and Cadasa have the Sxx #### format, but there is a dash between the third letter and first digit. Those are issued sequentially. In 2011, Hsing Yang province was created and it took the R code. Some letters were also allocated to special plates. E was allocated to motorcycles, Q was allocated to temporary plates, V was allocated to the government of Cadasa, X was allocated to trailers, Y was allocated to the military, and Z was allocated for police cars. They use the Lxx-###S format, with L being the code for the special plate.

Motorcycles
Prior to 2000, motorcycles shared the same format as passenger car plates. Motorcycles now have the prefix E followed by the location code, a letter, and 5 numbers. They are white on blue.

Goverment of Cadasa vehicles typically have the prefix V. Before Ganpung was created in 1972, G was used. They are black on yellow. For presidential vehicles, the serial format is PC 1 to PC 5 (PC stands for President of Cadasa in Cadasan).
