How to tell a person's age from the 15 digit of the ID card?

First of all, find out the ID number of 15:

15 digit ID number: 51170280022130.

The first six digits indicate the address code, accurate to the county.

6 to 12 bits indicate the date of birth, and the format is yyMMdd.

The last three digits of the serial code indicate the serial number of the same area, and the odd number of the serial code is assigned to men and the even number to women.

First of all, the date of birth of the 15 digit ID number is filled in the format of YYY-MM-DD.

For example, the original date of birth 15 digit was changed from 80 10222 to 19800222, and the revised digit became. 5 1 1702 19800222 130。

Calculate the modified 17 digits above:

Multiply each bit of the above number respectively according to the number set order of the following weighting factors and sum them up.

Weight factors {7,9, 1 0,5,8,4,2,1,6,3,7,9,10,5,8,4,2}.

take for example

5*7+ 1*9+ 1* 10+。 . . . +0*2=224。

Calculate the modulus of the sum obtained above, and then get the data of the corresponding position in the check code array according to the value of the modulus (note: the position index is calculated from 0) as the last bit of the 18-bit ID card.

Check code array {" 1 ","0 ","x ","9 ","8 ","7 ","6 ","5 ","4 ","3 ","2"}.

For example, the sum above is the modulus of 1 1, as shown below:

224% 1 1=4。

If the calculation result is 4, the value of the fifth bit of the check code array is 8 as the last bit of the 18-bit ID card.

Then we have calculated the converted 18-digit ID number: 51170219800221308.
