Everyone is born in this world. From the day we register, we have a unique identity password in the world, and this password is our ID number.
Although everyone has their own unique number, do you know what the meaning of this string of familiar numbers? Today, the creator of Xigua Video, Mr. Li Yongle and , will interpret the hidden information in our ID number for us.
Regional birthday information in ID card
There are 18 digits in an ID card number. So what does these numbers represent?
Watermelon Video Teacher Li Yongle gave us a detailed explanation today.
Some friends who have taken the junior high school entrance examination or the college entrance examination may notice that when registering, why do the numbers in front of the ID card used by the students and the students when registering are basically the same?
This is because the first 6 of the 18-digit numbers of the ID card represent our region, and each two numbers represent provinces, cities and regions respectively. Naturally, the numbers in front of the ID card are the same for friends in a region. The first 6 digits of
represent the region, and the numbers behind are not taken casually. The eight digits in the last
are taken from the date of birth of each of us. If you were born on October 19, 2020, then the 7th to 14th places in your ID card is 20201019.
Remembering your ID number is equivalent to remembering your birthday. Isn’t it very convenient for our memory?
sequence code
Teacher Li Yongle said in the video that our country is vast and has a large population. There are many people born in the same place at the same time in the same year and month. So how should these people distinguish their ID numbers?
followed the order of the birthday number to solve this problem for us. The function of
sequence code is to prevent the ID number of people born at the same time in the same place and the same year from being repeated. Different sequence codes are controlled in the hands of different police stations. Will each newborn born at the same place and the same year on the same day get its own order? This plays a distinctive role.
There is another clever little detail here. In the third digit of the verification code, if it is an even number, then this is a girl. If it is an odd number, then it is a boy. Isn’t it very interesting?
clever verification code
The last digit of the ID card is the verification code, which has 11 possibilities, namely the numbers 0-9 and the letter X.
As Xigua Video teacher Li Yongle said, the most clever design of the ID number is the 18th digit, because this number itself does not have any special meaning, but it can immediately tell whether the number you entered is correct or not.
verification code is not a one selected by any institution or individual, but is a result calculated using a very complex calculation method.
When we go out, we often encounter situations where we need to enter our ID number. When you enter any of these 18-digit numbers incorrectly, when the results obtained after these numbers are calculated are different from the verification code, it means that your ID card is entered incorrectly, which is very convenient.
If in this case, unless the previous number is entered incorrectly, the verification code is also entered incorrectly, and the previous number is exactly equal to the error verification code you entered after the calculation results, then this can be said to be very slim. The existence of a check code like
greatly reduces our input errors, and it can be said that the design is very clever.
