Why can't an old license plate be transferred to a new car on the same day?

[IsabelleLee]

Because the procedures are relatively complex. In fact, the process of retaining an old license plate for a new car can be completed on the same day, but the actual time for reinstalling the old plate depends on when the new car is delivered. Below is relevant information about license plate numbers: 1. Function of license plate numbers: A license plate number is an identifier for a vehicle, much like an ID number for a person. License plates serve as a numbering and information registration system for vehicles, primarily enabling identification of the vehicle's registered region and allowing access to the owner's details and registration information. 2. Motor vehicle license plate numbers: A motor vehicle license plate number consists of a registration authority code and a plate number. For automobiles, the plate number has a two-row structure: the upper row displays the registration authority code, while the lower row shows the plate number. The registration authority code is a 2-character combination, comprising a Chinese character (abbreviation of the province, autonomous region, or municipality) and an English letter (code for the vehicle management office).
