Can social security be paid repeatedly?

Legal analysis: First, if you work in two units, it is impossible to pay twice in the same overall planning area. The premise of unit payment is to sign a labor contract with the employer to form a labor relationship. When working in the employer, the employer should report the payment roster to the social security department for review. But in reality, we can't work in two units at the same time. Even if we work in two units at the same time, if we work in the same social security co-ordination area, if unit A pays, unit B can't pay, because the social security accounts are all my ID cards and names, even if the names are the same, the ID numbers can't be the same. Second, there may be repeated participation in cross-planning employment. For example, if you leave your job without pay in your original unit, the unit that left your job without pay has already paid social security for yourself, and after you work in the new unit, you are also paying social security. But in this case, you have to pay across the co-ordination areas, which is impossible in the same co-ordination area. Another situation is to retire to a new unit during the unit processing. For example, in the original unit, the employer should not only pay the salary for internal retirement, but also be responsible for paying social security for retired employees. Employees who retire from work go out to work, and when they arrive at a new unit, the new unit also pays social security, but it must also be cross-regional because many social security places are not connected to the internet outside the overall planning area.

Legal basis: People's Republic of China (PRC) Social Insurance Law.

Article 57 An employing unit shall, within 30 days from the date of its establishment, apply to the local social insurance agency for social insurance registration with its business license, registration certificate or unit seal. The social insurance agency shall, within fifteen days from the date of receiving the application, examine and issue the social insurance registration certificate. Where the social insurance registration items of the employing unit are changed or the employing unit is terminated according to law, it shall, within 30 days from the date of change or termination, go to the social insurance agency to handle the change or cancellation of social insurance registration. The market supervision and management department, the civil affairs department and the organization management organ shall promptly inform the social insurance agency of the establishment and termination of the employing unit, and the public security organ shall promptly inform the social insurance agency of the birth, death, household registration, migration and cancellation of the individual.

Article 58 An employing unit shall, within 30 days from the date of employment, apply to the social insurance agency for social insurance registration for its 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.
