How do the first 14 digits who know the ID number know the latter?

The first six digits of the ID number are the local administrative division code and the middle eight digits are the date of birth code. What is the date of birth? For example, the eight digits are 1997 65438+ 10/,which means 1 99701,and the digits from 15 to 17 are serial numbers, which are random.

In addition, the number of the citizen's ID card is unique and will remain unchanged for life, and will not change under the premise of no wrong number or duplicate number. Even if the account is moved, the first six area codes will not change.

Your question can't be answered. If you need to check someone's ID number, you need to go to the public security checkpoint for proper reasons.

By the way, there should be something wrong with the administrative division code 62 1 100, which is the code of Dingxi, Gansu. However, the first six digits of a person's ID number must be in a county (county-level city), and it is impossible to go only to prefecture-level cities, so the code of 62 1 100 will not appear on the ID card, only the code of the county can appear.
