Can social security be paid by two units at the same time?

Legal analysis: social security cannot be paid by two companies at the same time. If a person has two pension insurance relationships, it should be cleaned up and the rest of his personal account should be returned to him at one time.

Legal basis: Notice of Ministry of Human Resources and Social Security on Several Issues Concerning the Transfer and Continuation of the Basic Old-age Insurance for Employees in Urban Enterprises V. Handling of Repeated Receiving Basic Pensions. After the implementation of the "Interim Measures", the insured who repeatedly received the basic pension, after consultation with the social insurance agency, decided to keep one of the old-age insurance relationships and continue to receive treatment. After the other old-age insurance relationships were cleared, the remaining part of the personal account was returned to him at one time.
