Four digits after ID card 6348 fortune telling _ ID card number four digits after fortune telling

What do the last four digits of the ID card represent?

Each of us will basically choose the right time to apply for an ID card according to our own situation. 18 on the ID card has different meanings, and the last four digits are especially important. They represent different meanings.

The first two digits of the last four digits, namely 15. 16 digits of the whole number combination, represent the code of your local police station, and 17 digits represent gender. If it's a male, it's an odd number; if it's a female, it's an even number. If the whole first 17 bit is traceable, then 18 bit is a random number. Which is what we call a check code. The check code is divided into the number 0- 10, but many people find that 10 never appears on the ID card. In fact, 10 is presented in another way, which is X that we often see. Therefore, it is not a special population to say that the last digit of the ID card is X, just because if it is represented by 10, the ID card will change from 18 to 19, which obviously does not meet the national standards. Then why not change 10 to someone else? Because X is Roman numeral 10, X will be used to represent 10.

In addition, our first 14 position also has a unique meaning. For example, our top 6 places are the corresponding provinces, autonomous regions and municipalities, and will be sorted according to the address where you first applied for your ID card. Even if you change your residence address or household registration for various reasons in the future, your top six are fixed. The 7th-14th bit represents your date of birth, so don't look at this tiny18th bit, which contains a lot of things.

Therefore, when we use the ID card, we must take good care of it, because it is the only ID number you have compiled since birth and will not change. Don't let interested people steal their identity information.
