Is there an upper limit for the longest period of social security contributions?

Legal analysis: the minimum payment period of social security 15 years, and the maximum is not limited. Social insurance refers to a non-profit social security system with income redistribution function, which is used by the state to prevent and force most social members to participate.

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.
