How to find out how many social security cards you have?

Legal analysis: Everyone can only apply for one social security card, because the social security system platform is shared. Where can I get a medical insurance card or not? You can bring your ID card to any bank to find out which specific bank your medical insurance card is applied for. If not, I can also apply for a medical insurance card in any bank, and the bank will open an account with the Social Security Bureau for you.

Legal basis: Article 31 of the Social Insurance Law of People's Republic of China (PRC), social insurance agencies may sign service agreements with medical institutions and pharmaceutical trading units to regulate medical service behavior according to the needs of management services. Medical institutions shall provide reasonable and necessary medical services for the insured.
