Military license plate

Using the seventh generation (model 04), it was officially opened in May 20 13. This code plate is called "20 12" military vehicle number plate. The new number plate adopts six technologies: information anti-counterfeiting, fluorescence anti-counterfeiting, 3D optical anti-counterfeiting, laser stereo hiding anti-counterfeiting, laser engraving coding anti-counterfeiting and special pattern anti-counterfeiting. ETC technology is also applied. "20 12" military vehicle license plate is divided into official license plate, trailer license plate, test license plate, temporary license plate and flight support vehicle.

Vehicles with the first four military license plates are allowed to drive on the road, and flight support vehicles with special license plates are only allowed to drive in the designated area of the flight field. Among them, the official number plate is divided into big car number plate, small car number plate and motorcycle number plate. The official number plate consists of prefix, prefix, separator (car number plate) and serial number. Among them: prefix, using capital Chinese phonetic alphabet; The word number one, in capital letters; The spacer is square; Serial number, the number plate of cart and car is 5 digits, and the number plate of motorcycle is 4 digits.

License plate refers to the vehicle number plate, which is a sign hanging on the front and rear sides of the car. Commonly used materials are aluminum, plastic or stickers, and the license plate will show the license plate number, registration area or other basic information about the car. The license plate is the number of each car. Its main function is to know the province, city and county where the car belongs through the license plate, and the vehicle management office can find the owner according to the license plate.

The license plate number can be designed by yourself, except for the first two in accordance with national regulations, others can be freely selected.

At present, the civil license plate is Type 92, which has been used nationwide since July 1994.

The first number of the license plate is Chinese characters: it represents the provincial administrative region where the vehicle registered permanent residence is located, and is the abbreviation of each province, municipality directly under the central government and autonomous region. For example, Beijing is Beijing, Shanghai is Shanghai, Hunan is Hunan, Chongqing is Chongqing, and Shandong is Shandong.

The second place of the license plate is English letters: it represents the prefecture-level administrative region where the vehicle account is located, and it is the letter code of each (prefecture-level city, region, autonomous prefecture and league). Generally, the provincial vehicle management office ranks according to the situation of the local administrative regions: (the letter "A" is the code of the central city of the provincial capital, capital or municipality directly under the central government, and the following letters are ranked in no particular order);

In addition, I and O are skipped when compiling English alphabet codes of prefecture-level administrative regions, and O is often used as police cars or government agencies (see "Police car license plate" in this entry). (the letter o in the army and the armed police has nothing to do with this. See "Military License Plate" and "Armed Police License Plate" in this entry).
