According to the third paragraph of Article 58 of the Social Insurance Law of People's Republic of China (PRC), the state establishes a national unified personal social security number, and the personal social security number is a citizen identity number. It shows that the social insurance relationship can only be unique, because the citizenship number corresponding to the social security number is unique.

If there are two social security accounts, you can apply for the merger of social security accounts in different places according to the National Administrative Measures for the Transfer and Continuation of Social Security Relations, and transfer the social security relationship to one. As for the other social security account, it is still valid even after suspension. When the social security account in different places is merged, it can be transferred to the social security account of the unit with longer working hours.

Therefore, the insured person cannot pay two social insurances at the same time, and if one of them needs to pay social insurance repeatedly in different places, it needs to be transferred or surrendered. Therefore, if you accidentally repeat the payment, you can move to a place and then return the repeated part.

Extended data:

In addition, if social security is paid repeatedly in different provinces, if you want to surrender, you can't return it in full. Only the endowment insurance can be refunded, and the money in the personal account is refunded, and the part paid by the unit is not refunded. Unemployment insurance, maternity insurance and work-related injury insurance are paid by the company and cannot be withdrawn or transferred. Endowment insurance and medical insurance can be transferred in different places.

Therefore, if the payment is repeated, you can apply for the transfer of pension insurance and medical insurance, and submit the payment voucher of one of them to another local social security agency for transfer. After the transfer is successful, the social security agency will refund the individual's repeated payment.

Those who pay two social insurances cannot enjoy double social insurance benefits. Take medical insurance as an example. If the insured is hospitalized, he can only be reimbursed once according to relevant regulations. When urban old-age insurance is paid repeatedly, only the payment period of old-age insurance is calculated, and the pension received after retirement will not increase because of repeated payment.

The years of repeated payment of social security cannot be accumulated, and everyone can only choose one place to receive pension benefits when they retire. Even if both places meet the conditions for applying for a pension, they can only choose one place to go through retirement procedures and receive a pension.
