What does each digit of the ID number mean?

1-2 codes of provinces, autonomous regions and municipalities directly under the central government;

3-4 digits of code of prefecture-level cities, leagues and autonomous prefectures;

5-6 county, county-level city and district codes;

7- 14 date of birth, such as 19820426 for1982 April 26th;

The number 15- 17 is the sequence number, in which 17 (the penultimate place) is the singular number of men and even women;

18 bits are check codes, 0-9 and X. As mantissa, check codes are calculated by bringing the first 17 bits into a unified formula, and the calculation result is 0- 10. If someone's suffix is 0-9, there will be no X, but if the suffix is 10, it will be replaced by X, because if 10 is used as the suffix, then this person's ID card will become 65438. X is the Roman numeral 10. Replace 10 with x.

For example:

The ID number 3302261982042600 1 2 means: 33 is Zhejiang, 02 is Ningbo, 26 is Ninghai County, the date of birth is1982, April 26th, the serial number is 001,and 2 is the check code.
