What do the letters on Shanghai license plates represent?

[EdenLee]

Shanghai license plate letters represent the following: Hu A, Hu B, Hu D, Hu E are for the urban areas of Shanghai, while Hu C is for the outer suburbs. Shanghai car license plates are not allocated based on administrative districts but rather in chronological order, starting with Hu A. Once all the numbers in one letter series are exhausted, a new letter is introduced. Shanghai car license plates come in four colors: yellow, blue, white, and black. The second character on the license plate is an English letter, representing the prefecture-level administrative region where the vehicle is registered. This includes prefecture-level cities, regions, autonomous prefectures, and leagues, with the letter codes generally assigned by the provincial vehicle management office based on the status of each prefecture-level administrative region. The letter A typically represents the capital city, provincial capital, or the central urban area of a municipality directly under the central government, with subsequent letters assigned without any particular order of precedence.
