How to transfer the age of military personnel to social security, and what procedures are needed?

I need to bring the following materials to the social insurance agency for the transfer of military service to social security: ID card: used to prove personal identity. Military personnel files: including enlistment, retirement and other related records. Discharged certificate: It proves that soldiers are discharged from active service. Payment voucher of basic old-age insurance for retired military personnel: it proves that the military personnel have been insured during their service. Transfer and connection information table of retired pension insurance for military personnel: record the information of military personnel's participation and transfer and connection. Copy of bank remittance voucher: it proves that the insurance premium of soldiers has been paid. In addition, according to different situations, it may be necessary to provide other relevant materials, such as labor contracts. After processing, you can log on to the local social security website to check the social security payment period and confirm whether the military age has been included in the social security period. If the military age is not included, you can explain the situation to the social security manager of the unit and follow the instructions of the social security agency.
