Do I have to change my social security card when it expires?

Yes, the social security card must be replaced when it expires, so as to avoid various problems in the subsequent use of the social security card. The expiration of the social security card will affect our medical insurance reimbursement and pension collection, so we should replace it in time before it expires. And you can't get the social security card in time, sometimes it takes ten and a half days. It is recommended to replace it in advance.

Legal basis: Article 2 of the Social Insurance Law of People's Republic of China (PRC) The state establishes social insurance systems such as basic old-age insurance, basic medical insurance, industrial injury insurance, unemployment insurance, maternity insurance, etc., to protect citizens' right to get material help from the state and society according to law in case of old age, illness, industrial injury, unemployment and maternity.
