Will the social security card replacement number change?

Legal analysis: it will change. The card number of the social security card is 12 digits. When the card is lost, replaced or changed, the card number will change. However, the first nine digits represent personal identity and remain unchanged when changing cards. Require hospitals to use 12 digit card number to judge the use of cards (such as taking medicines with cards); For personal applications (such as calling personal medical records), the first 9 digits must be used for retrieval.
