Vehicle license plates used in Peninsular Malaysia start with a letter of the alphabet. They do not use a checksum digit, unlike number plates from Singapore. Vehicles registered in the various states begin with specific letters as follows:
B: Selangor, including plates registered in Kuala Lumpur before the city separated as a Federal Territory in 1974.
J: Johor, including Government (JDT**) and Johor Military Force or Askar Timbalan Setia Negeri (JMF)
K: Kedah, including Langkawi (KV)
N: Negri Sembilan
Vehicles registered in the federal territories:
PUTRAJAYA as starting text: Putrajaya
W: Kuala Lumpur, issued after the city achieved a Federal Territory status in 1974. The Kuala Lumpur plate is the most numerous license plate issued, with a total of over 4 million plates issued, as of April 2007. Up to 1957, W was the code for Province Wellesley.
Peninsular Malaysia Motor Dealer's (Trade) plates are fashioned with white letters on a blue background using the "L 123 L" format, where the first letter is the state code and the final letter is a serial, as are the numbers.

Vehicles registered in the states of Sarawak and Sabah are allocated vehicle number plates commencing with the letters Q (Sarawak) or S (Sabah). Then follows the regional code and a serial number - when 9999 is reached a serial letter is used, in alphabetical order, to augment.
In Sarawak it follows the regional code new version ("QKA 1234") or the old version ("KA 1234 Q"). Before Sarawak joining Malaysia, the plate number didn't consist of the letter "Q".(" KA 1234"). However the letter "K" which is the area letter of Kuching is same as the state of Kedah. So in the 1988 the JPJ change the regulation by adding the letter "Q" on the last number for all car that register in Sarawak. The new version are set in 1991 to replace the old version which the "Q" is written on the last number.
QA and QK: Kuching
QB: Sri Aman
QC: Kota Samarahan
A variety of the old plate codes was such as "6D" and "7D". ("6D 1234 Q" / "6DA 1234 Q") : The letter "D" stood for 6th. Division (now QR-Sarikai) or 7th. Division (now QP-Kapit).
Sarawak Motor Dealers' (Trade) plates vary only in their colour, which is white on a red ground.
In Sabah this serial letter follows the serial number ("SA 1234 A"), as for the West Coast of Sabah or "Pantai Barat", the vehicles registered at the main city of Sabah followed by the newer format "SAA 1234 A" in 2000 after the complete use of postfix letter "Y" in the year 1999). The rest of the regions are still using the old one, so far it is either not confirmed yet or not known yet if they will follow the newer format of the West Coast region. Thus, it is pending to the Sabah State Government's decision.
SA: Kota Kinabalu and Kota Belud
SD: Lahad Datu
Before 1980s the number plates in Sabah had added prefix letter "E" (East Malaysia),("EJ 1234";"EJA 1234. The 'E' had been added to overcome confusion with vehicles from mainland Malaya, but those plates then became identical to Singapore some of which also started with the letter "E". A re-think was needed.
EJ = Jesselton
ES = Sandakan
ET = Tawau
ED = Lahad Datu
EU = Keningau
EK = Kudat
EL = Labuan
Sabah Motor Dealers' (Trade) plates are red on white in the format 1-3 numbers followed by a district letter, usually J, for the capital, Kota Kinabalu (formerly Jesselton).

United Nations uses UN and some international organizations have the code PA. UN plates may be seen at UN headquarters at Damansara Heights, while a few PA plates can be spotted at the WorldFish Center in Penang.

Semi-trailers feature two license plates, place at the rear of the trailer. One is designated for the tractor unit, and another for the following trailer itself. The tractor unit's license plate follows that of a normal ABC 1234 arrangement in accordance to those of the tractor unit itself, while the trailer's own license plate features a T/ prefix, followed by the trailer's normal registration number. Thus, an example of a trailer's license plate tends to read as followed: T/BA 1234. In a handful of cases, the T/ prefix is superscripted.
