Can Sihong's social security card Suqian be used?

A city can be used, but it cannot cross the city.

Social security cards generally cannot be used across cities. If cross-city and social security in the province are not shared, workers can't use social security cards when they leave their urban areas for other cities. Whether it can be used varies from region to region, and you can consult the local social security agency.

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.
