Is it necessary to apply for social security card?

Legal analysis: no, there is no requirement to do it, but it is best. At present, the social security card issued by the school only has the function of medical insurance, and the medical fee can only be reduced. Other expenses (treatment fees, injection fees) must be paid at their own expense. After graduation, the original student medical insurance card function will be automatically cancelled, and you need to buy urban workers' medical insurance or residents' medical insurance to enjoy medical insurance benefits.

Legal basis: Article 70 of the Labor Law of People's Republic of China (PRC) The state develops social insurance and establishes social insurance system and social insurance fund, so that workers can get help and compensation when they are old, sick, injured at work, unemployed and have children.
