What's the meaning of the last X of ID card? Reveal the little-known secret of ID card
4hw.org: in general, our ID cards are composed of 18 digits. However, I believe many students also know that some people have a capital letter X behind the end of their ID cards. Do you know what this x means? Let's work with Xiaobian to find out the answer!
There are not a few curious netizens about this. Some people say that the people who had registered their account in that year mistakenly typed it, and some say that the people who had fostered it just typed it. There are netizens with big brain holes who said that the people who had ID card with X were actually x agents scattered in the grass-roots level by the state!
Well, stop guessing. CCTV news has popularized this cold knowledge recently: the last one of ID card is the check code calculated according to the first 17 digits. If the tail number is 0-9, there will be no X. if it is 10, use x instead. This can ensure that the ID number is not many.
Netizens comment on 'mysterious letter X':
My friend told me about one of the best things she'd ever done. She didn't know that there was an X at the end of her ID card before, and then she filled in the form once, glanced at the X at the end of someone else's ID card number, thinking that it was so mysterious to fill in an ID card, and then she filled in the last four digits of her ID card number as XXXX.
Just went to college that meeting, the student elder sister said that the meal card password is the last six of the ID card number, when I spent too much money in the supermarket, I looked at the password machine with only ten numbers, and silently returned the things.
I always firmly believe that x is because I was chosen to complete a mysterious task one day, such as the control robot in the Pacific Rim, the tomb robbing robot, the tomb robbing robot, the excavation of large-scale ancient tombs, the invasion of an enemy, and the communication and friendship with aliens.
I always thought I was the X-Men scattered around the world.
