Which department does the white license plate starting with 'sb' belong to?

[SanCamilla]

White license plates starting with 'sb' belong to the Political Department of Shenyang Military Region. Here is some information about white license plates: In the newly issued military license plates, the first letter indicates the jurisdiction. 'V' represents units directly under the military region and headquarters, 'Z' represents secondary departments of the headquarters, while the following letters directly use pinyin, such as 'N' for Nanjing and 'S' for Shenyang. Additional information: 1. White license plates: These are used for police vehicles of the political and legal departments, vehicles of the armed police forces, and military vehicles of the People's Liberation Army. 2. Blue plates with white characters: These are for ordinary small vehicles, including special number segments for government agencies and administrative vehicles other than police vehicles of the political and legal departments. 3. Yellow plates with black characters: These are for large vehicles, motorcycles, and driving school training vehicles. 4. Black plates with white characters: These are for foreign-related vehicles, with a design basically the same as blue plates.

Let me share some common knowledge about license plates. White plates are mainly divided into military and police plates. Among them, those starting with 'SB' are particularly rare. According to my research, they might be internal plates of the General Political Department of the PLA. Such plates directly indicate the unit's name, for example, '军A' stands for the Central Military Commission Office. However, military plates have now been standardized, and those starting with 'SB' are likely old-style plates. If you encounter such a plate on the road, remember not to pick a fight with them!

A white license plate with the letter combination 'SB'? This is most likely a special internal-use vehicle management plate. In the past, some specialized plates for the General Logistics Department and the Armed Police used such arrangements, but the specific department would depend on the prefix number segment. Actually, the more common ones are the white plates with black characters bearing the characters 'Shi' (for embassy) or 'Ling' (for consulate), which are diplomatic license plates. Nowadays, ordinary white plates are rare, even the police have switched to new-style plates. If you really want to confirm, it's recommended to directly check the registration information at the vehicle management office.

I've seen vehicles with white license plates starting with 'SB' a few times and specifically consulted a traffic police friend about it. This type of license plate was largely phased out after the 2016 reform, when various self-made plates were uniformly cleared. The existing ones are mainly emergency vehicles of the armed police and firefighting systems that still use a similar format, with clear unit identification on the vehicle body. However, be aware that there are many cloned plates nowadays, so it's best to note down the license number and report it if you encounter anything suspicious.

White license plates can be categorized into several types: diplomatic plates with black characters, military and police plates, as well as special operation vehicles. The SB code does not belong to the regular sequence and might serve as internal passes for certain state-owned enterprises. In the past, large transport vehicles in the metallurgical system frequently used these, and currently, only registered emergency vehicles retain them. If genuinely interested, you can photograph the license plate number and submit an inquiry request on the 12123 platform.

Having worked in auto repair for so many years, the white license plates I've seen most often are still those on engineering emergency vehicles. The SB code is most likely for special-purpose vehicle plates in the water and electricity systems, such as substation maintenance trucks. Their distinctive feature is the enlarged black characters on a yellow background at the rear of the vehicle. However, it's important to note that since last year, various regions have been cracking down on homemade license plates. Existing vehicles of this type must now display reflective markings and the name of the operating unit to remain compliant.
