Vehicles from Hong Kong and Macau are required to apply for licence plates, usually from Guangdong province, to travel on roads in mainland China.
1986-series plates are allowed to have the first number in the serial replaced by a letter with a special meaning, such as T for "taxi", Z for 自备车 (zìbèichē, "self-reserved vehicle"), G for 个体户 (gètǐhù, "entrepreneur").
Therefore, there had become a need to insert Latin letters into the license plate to increase the number of possible combinations (for the full list of alphanumeric sequences permitted see below).
Should the number of combinations issued exceed 60% of the theoretical capacity of its type, the combination next in the list may be put into use after approval from the Vehicle Management Office of the provincial Public Security authority and reporting to the Vehicle Management Office of the Ministry of Public Security.
Note: Y and N in this table reflects whether or not this combination type may be used in registration plates with 4 or 5 places for digits/numbers, while D and L represents any permitted digit or letter respectively.
The black plates are still issued to those who registered in both mainland China and Hong Kong or Macau, specifically in Guangdong province, which are in the sequence of 粤Z·####港/澳.
The plates’ combination of the Chinese People's Armed Police Force ("武警") begins with the pinyin wujing abbreviation WJ.
The 2012 series of CAPF vehicle registration plates is in the WJ P NNNNL pattern, where the stands for a Chinese character i.e. 京 for Beijing, serving as the provincial identifier, and the L denotes the first letter in pinyin of the branch of service.

Vehicles featured in these shows often carry registration plates with non-valid provincial abbreviations and/or invalid typefaces.
Licence plates with a black background and the character 港 or 澳 in place of the last number are used for Hong Kong and Macau vehicles, respectively, when they engage in cross-border traffic to and from mainland China.
Interim licence plates are a piece of paper to be affixed to the front of the vehicle's window, usually valid for 15 days.
However, although the usage of "CHN", to designate China, was not permitted in the plates, that restriction, oddly enough, did not apply to the letters "PRC".)
In late August 2002 new 2002 standard plates had their issuance temporarily interrupted, officially for technical reasons, but actually because some number/alphabetical combinations of a controversial nature in mainland China were utilised.
One of the biggest controversies was when a vehicle with plate number USA-911 was spotted in Beijing, causing an uproar as it was taken to be a reference to the September 11 attacks, and as such was criticized as being disrespectful to Americans.
