How to judge men and women by the tail number of ID card

Judging men and women by the tail number of the ID card can be distinguished by the penultimate position of the ID card.

The penultimate digit of the ID card is odd for men and even odd for women. The penultimate digit of the ID card here refers to the ID number of 18 digits. If it is an old ID card, there are only 15 digits, and the digital ID card with 15 digits is the last digit. Similarly, men are odd and women are even.

18 of the ID card has the meaning of personal information, including the date of birth and other information. The old ID card was 15 digits. An ID card is a document used to prove one's identity, the only tool to prove one's citizenship, and the ID number on it is also unique to oneself.

Matters needing attention in using ID card

1. When using your ID card, if you find someone copying or scanning your ID card without authorization, you should stop it in time to avoid unpredictable consequences for yourself, and the information on your ID card cannot be recorded casually.

2. When you walk or pick up someone else's ID card by other means, don't use it casually. It is best to hand it over to the local police station or public security department in time. Fraudulent use or fraudulent use of other people's identity cards is an illegal and criminal act, and will eventually be punished by law.

When you give a copy of your ID card to others, you'd better indicate it on the copy. Comments are usually written in three lines. After writing, draw a horizontal line behind each line to prevent others from adding other content.
