Social security in Shaoxing and Hangzhou is universal.

Legal analysis: 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 basis: Article 58 of the Social Insurance Law of People's Republic of China (PRC) stipulates that the employer shall apply to the social insurance agency for 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.
