Are there i and o in license plates?

[Elsa]

License plates do not contain the letters i and o. The license plates used by vehicle owners distinguish provinces and cities through a combination of Chinese characters and letters, followed by a small dot separating the subsequent numbers. The following five digits can form the license plate through a combination of letters and numbers. License plate naming rules: 1. The first character of the license plate is a Chinese character, representing the provincial-level administrative region where the vehicle is registered; 2. The second character of the license plate is an English letter, representing the prefecture-level administrative region where the vehicle is registered; 3. The letter A is the code for the capital city, provincial capital, or central urban area of a municipality directly under the central government. When assigning English letter codes to prefecture-level administrative regions, the letters i and o are skipped; 4. There are three rules for license plate serial number encoding: each digit of the serial number uses Arabic numerals, each digit of the serial number can use English letters individually, but the letters O and I among the 26 English letters cannot be used. The serial number allows for the presence of two English letters, but the letters O and I among the 26 English letters cannot be used.
