Social security card has no bank card number.

The social security card has no bank card number, which means it is an old social security card and needs to be replaced with a new one. Social security cards currently in operation are generally dual-core, and bank cards and social security cards are different parts. On the reverse side of the card, the bank card number and ID number are indicated next to the photo. However, some old social security cards are not indicated. In the old version, social security cards and bank cards were separated. Now all the new versions have been merged, but the social security fund inside can't be used as cash. If you want to replace a new card, you must first cancel the old social security card, handle the new social security card in the social security center after consultation with the unit, and submit an application for social security card in the social security center with your valid ID card and old medical insurance card, and then find relevant personnel to handle it.
