What should I do if I have been re-employed but the former company closed down and the social security has not been transferred out?

Legal analysis: the new employer shall submit a written application for the transfer and continuation of the basic old-age insurance relationship to the social security agency, and then the social security agency in the place where the new employer is insured will review the application for transfer and continuation within 15 working days, and the social security can be restored.

Legal basis: Article 8 of the Interim Measures for the Transfer and Continuation of the Basic Old-age Insurance Relationship for Employees of Urban Enterprises issued by Ministry of Human Resources and Social Security and the Ministry of Finance, the procedures for the transfer and continuation of the basic old-age insurance relationship for cross-provincial employment of the insured shall be handled according to the following procedures: (1) After the insured establishes the basic old-age insurance relationship in the new employment place and pays the fee, the employer or the insured shall submit a written application for the transfer and continuation of the basic old-age insurance relationship to the social security agency in the new insurance place; (2) The social security agency of the newly insured place shall, within 15 working days, review the application for transfer and continuation, send an acceptance letter to the social security agency where the insured person's original basic old-age insurance relationship is located, and provide relevant information; Do not meet the transfer conditions, make a written explanation to the applicant or the insured; (3) The social security agency where the original basic old-age insurance relationship is located shall handle all the transfer and connection procedures within 15 working days after receiving the acceptance letter; (4) After receiving the basic old-age insurance relationship and funds transferred by the social security agency where the insured person's original basic old-age insurance relationship is located, the social security agency in the newly insured place shall complete the relevant procedures within 15 working days, and notify the employer or the insured person of the confirmation in time.
