Is the personal number of the social security information system the social security card number?

The social security card number is different from the social security personal number, and the personal social security number is in the social security manual. If you don't know the social security personal number, you can go to the social security service desk with your ID card, as long as everyone who participates in the insurance has a personal social security number.

Social security number and social security card number are two concepts. Social security card numbers are like bank card numbers. It only refers to the medium size of this card, not the only one. If a citizen loses a replacement, his social security card number will change, so he can't use his ID number. Social security number is the only inquiry and identification account number of citizens in the social system. The social security card number can be changed, but it will not change.
