Can I use my social security card anywhere?

Legal analysis: it can only be used locally, because the current policy is mainly aimed at the overall planning of provinces and cities, and there is no national overall planning, so it cannot be used elsewhere. If the company helps to pay social security, then the social security relationship is in the company's location, and you can only enjoy the relevant preferential policies of social security in the company's location. If you are seeing a doctor in a different place, you can see a doctor in a designated hospital or reimburse your medical expenses later.

Legal basis: Article 58 of People's Republic of China (PRC) Social Insurance Law. The employing unit shall handle social insurance registration for employees within 30 days from the date of employment. If the social insurance has not been registered, the social insurance agency shall verify the social insurance premium it should pay. Employees-free individual industrial and commercial households who voluntarily participate in social insurance, part-time employees who do not participate in social insurance in the employing unit and other flexible employees shall apply to the social insurance agency for social insurance registration. The state establishes a national unified personal social security number. Personal social security number is a citizen's identity number.
