Are there no letters I and O on license plates?

[DeAiden]

Currently, license plates do not include the letters I and O. The functions of license plates are: 1. To number and register information for vehicles; 2. To identify the region to which a vehicle belongs; 3. To allow the lookup of vehicle owner and registration information based on the license plate number. Types of license plate numbers: 1. White represents military and police plates; 2. Blue represents ordinary small vehicles with fewer than 7 seats; 3. Yellow represents ordinary large vehicles; 4. Black represents license plates for foreign enterprises. The composition of a license plate is: 1. A Chinese character, which is the abbreviation of the province where the vehicle is registered; 2. An English letter, representing the prefecture-level city code where the vehicle is registered; 3. A sequential number.
