My social security used to be with the Agricultural Bank of China, but now it's with the Industrial and Commercial Bank of China when I change jobs, do I need to change my card?

On the question of replacing your social security card, you don't really need to change banks as often as you change jobs. The main identification of the medical insurance card is based on the personal ID number, not tied to the work unit. Your social security card, whether it's from the Agricultural Bank of China or the Industrial and Commercial Bank of China, as long as it matches the information on your ID card, you will be able to manage your health insurance and personal accounts normally.

Medicare cards are special cards for health insurance personal accounts, handled by locally designated banks, and are used to record personal details, such as ID card number, name, and payment and consumption of account money. Participating organizations will credit the individual account funds to the card every month, and you can use it to settle your medical insurance bill at the hospital or to buy medicines at the pharmacy.

The social security card serves a wide range of purposes, not only containing personal social security information, such as pension and medical insurance payments, but also being used for identity verification and social security affairs, such as receiving pensions and registering for job-seeking and unemployment. Therefore, even if you change your workplace, as long as the basic information on your social security card does not change, you don't need to purposely change it because of a change in bank, just make sure to provide the correct ID number when you use it.
