Why is my social security card not my number to send a text message to remind me to buy medicine?

Maybe this is the mobile phone number you used before.

You can consult the relevant staff of the Social Security Bureau.

Social security card generally refers to the social security card of the People's Republic of China. The Social Security Card of the People's Republic of China is an integrated circuit (ic) card issued by local human resources and social security departments for various business fields of human resources and social security.
