The difference between social security card number and social security card number is that social security card also includes bank card number. The social security number is the cardholder's ID number and social security account number, while the card number on the social security card is the account number provided by the issuing bank and the financial account of the social security card. After activation, the cardholder can be used as a debit card, which has all the basic financial functions of a debit card. Social security card is the only sign that citizens participate in social security and enjoy social security benefits. Important information such as the cardholder's photo, social security number and bank card number are printed on the card surface. The social security card adopts the national unified standard, and the social security number adopts the citizenship number in accordance with the relevant provisions of the Social Insurance Law of People's Republic of China (PRC).
