What information can I see in the ID number besides my birthday?

Then we should have a good understanding of the coding rules of ID cards. The first six digits of the ID card represent the administrative division code of the county (city, flag, district) where the individual's permanent residence is located, and represent the post behind the area. The four digits are the year of birth, and the birthday is the year of birth. The digits 15 to 17 of the ID card are the serial numbers of people born in the same year, month and day in the area identified by the same address code. The seventeenth odd number is for men, the even number is for women, and the last one is the check code, which is represented by X in special cases.

So we see not only the birthday, but also the city and region where this person lives, and how old he is now, but this is not the most important issue, the most important issue is! You can see beautiful past lives! I remember my ID card, which has always been a pain in my heart. It was a bright morning, and Liu Hai and I embraced it, with a big back and a shiny forehead, and cooperated with the camera to reflect each other from a distance. Once, I used an ID card in my class, but the boys in my class saw it and didn't return it to me. My image is in class. . Maybe this is fate. Later, I really couldn't stand this photo, so I went home and reissued it. Although I can't say it's beautiful, at least I dare to show it to people now. So, if you like a girl, don't look at her photo, because this photo may be an explosion that killed Matt's head, or a square forehead, or something she doesn't want to witness in her life. Therefore, there are still many things you can see on your ID card.
