Distinguish between license plates 0 and 0.

The letter 0 of the license plate is different from the letter O. The letter O is a public relations vehicle and the letter O is cancelled.

In the use of letters and numbers of automobile license plates, only Arabic numeral 0 will be used, and the letter O will not be used. Therefore, we don't have to distinguish whether the zero we see in the license plate number is a number or a letter. It will only be the number 0, not the letter o. In order to avoid confusion or mistakes in license plate recognition, the use of the letter O has been excluded, and only the number 0 is used in the combination design of license plate numbers and letters.

When we choose the license plate number of the vehicle and look at the license plates of other vehicles on the road, we may wonder whether this 0 is the number 0 or the letter O. When we choose the number or look at the license plate, how can we tell whether the 0 in the license plate is a number or a letter?

The specific provisions of the coding rules are as follows:

Number of digits of serial number of license plate number: 2 digits, coding rules: English letters O and I are not used in the third digit of serial number; Number of digits in the serial number of the license plate number: 3 digits, and coding rules: Arabic numerals shall be used for each digit in the serial number.

Number of digits of serial number of license plate number: 4 or 5 digits, coding rules: English letters O and I are not used in the third digit of serial number; Number of digits of license plate serial number: 6 digits, coding rules: English letters O and I are not used in the third serial number.

According to the specific description of the coding rules in the above standard description, we can clearly know that all motor vehicle license plate serial numbers, from serial number 2 to serial number 6, will not use the English letters O and I.

Note that this is an industry standard specification, that is, the coding specification of motor vehicle numbers. Then, according to the standard specification, in the vehicle license plate number, the letter O will not be used, only the number 0 will be used, so there is no need to consider the distinction. This o is the number o, not the letter o.

At the same time, we also see from the industry standard coding rules that the English letters O and I are not used in the serial number of the license plate. Then, the 1 we see in the license plate will not be the letter I, but only the number 1.

The coding rules are stipulated in this way, mainly to avoid the confusion between the letter O and the number 0, and the letter I and the number 1 in the use of license plate numbers, so as to avoid mistakes in license plate recognition and affect the accuracy of license plate recognition.

In addition, it should be noted that the letter O is still used in the use of letters and numbers of motor vehicle number plates, but the use of the letter O is limited to the use of licensing authority codes.

That is, the letter after the license plate abbreviation is also used for special license plate letters, not for a license plate code, but for the license plate code of the administrative unit of the public security organ.

Using the letter O as the code name of the licensing authority, the use of the letter O license plate was gradually cancelled in the subsequent policy adjustment of regulating the use of license plates by local public security organs. The letter O was directly deactivated as the license plate issuing authority code, and the administrative license plate of the public security organ was also replaced by an ordinary license plate. The O-card is directly deactivated and no longer used on the motor vehicle number plate.
