Vehicle registration plates of Daidieu

Vehicle registration plates of Daidieu generally take the form NNX-#### for vehicles, with NN being the numeric location codes, X being a Bopomofo character, and #### being a random 4-digit number. Standard license plates have black characters on white background. Front plates measure 190 x 110 mm.



Pre-1984
Prior to the independence of Daidieu in 1954, plates followed the French Indochina format. Plates were white-on-black with the XXX#### format. XXX was the location code. while #### was the serial number. After 1954, the location code was changed to the Vietnamese name. During the Vietnamese occupation of Daidieu, the format remained unchanged due to its resemblance to the Vietnamese format at the time.

1984–present
In 1984, the plates were changed black-on-white. The format was also revamped, with the new format changing to NNNX-####. NNN represents the province/municipality, X was a Bopomofo character, and #### were digits. The three-digit codes refer to the various provinces of Daidieu. In 1987, the codes were replaced, with each province having 4 codes. In 2010, provinces began to issue plates with the NN#X-#### format. In 2012, as part of the new ASEAN license agreement, a blue stripe with the flag of Daidieu and the text "大趙" was added to the left.
