I know my birthday before and after my ID card, but I don't know how to check it.

If you know the birthday before and after the ID card, you can check the official household registration and ask the police about the date of the birthday record of the ID card.

1, according to the relevant public information and the relevant provisions of the National Identity Card Management Law.

2. There is a date of birth on the ID card, so the last 7~ 14 digits of the ID card are the date of birth specified in the ID card number.

3. Check the ID number or the relevant valid documents of the household registration book to check the birthday.
