Social security card card number and ID number are the same?

The social security card is a card issued by the social security department to record information about one's social security contributions and social security benefits. The social security card number is a unique identification generated by the social security department based on personal information, usually 18 digits. The ID card number, on the other hand, is a unique identifier generated by the public security department based on personal information, which is also usually 18 digits (or 17 digits plus a letter X). Therefore, the Social Security card number and the ID number are not the same.

The social security card number and the ID card number are not the same, but in practice, the social security card number and the ID card number are often associated.
