What if both cities pay social security?

Legal analysis: social security payment in many cities is handled by social security transfer, which is also divided into inter-provincial or intra-provincial transfer. The insured person is employed in cities and towns and continues to pay insurance premiums. No matter where the insured person is employed or insured, even if there is an interruption in the middle, he can add up the payment period and calculate the amount stored in his personal account together. Those who meet the conditions for receiving benefits can enjoy basic old-age insurance benefits. It's just that the procedures for inter-provincial transfer and intra-provincial transfer are different. It should be noted that only two of the five insurances can be transferred, namely, the personal account amount of endowment insurance and medical insurance, and the payment period. If it is transferred across provinces, most of the amount of pension accounts can also be transferred. If it is a provincial adjustment, it does not involve the overall planning part. Unemployment insurance, industrial injury insurance and maternity insurance in the five insurances cannot be transferred.

Legal basis: Article 17 of the Social Insurance Law of People's Republic of China (PRC), if an individual who participates in the basic old-age insurance dies due to illness or non-work, his survivors can receive funeral subsidies and pensions; Persons who have completely lost their ability to work due to illness or non-work-related disability before reaching the statutory retirement age can receive disability allowance. The required funds are paid from the basic old-age insurance fund.
