Is social security universal in all provinces?

Social security is universal, but social security cards cannot be universal. Because the current social security policy is coordinated by provinces and cities, there is no national coordination, so everyone is different in all aspects because of the different proportion of social security contributions in their respective regions.

Legal objectivity:

Article 58 of the Social Insurance Law, the employing unit shall, within 30 days from the date of employment, apply to the social insurance agency for social insurance registration for employees. 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.
