If I change my job, what about my old social security card?

Legal analysis: if employees pay insurance premiums, the relationship between basic old-age insurance and medical insurance can be transferred, the payment period can be calculated together, and the amount stored in individual accounts can be calculated cumulatively. No matter where the insured person is employed or insured, even if there is an interruption in the middle, the payment period can be calculated together, and the amount stored in personal accounts can also be calculated together. Those who meet the conditions for receiving benefits can enjoy basic old-age insurance benefits.

Legal basis: Article 19 of the Social Insurance Law of People's Republic of China (PRC), if an individual is employed across the overall planning area, his basic old-age insurance relationship will be transferred accordingly, and the payment period will be calculated cumulatively. When an individual reaches the statutory retirement age, the basic pension is calculated in stages and distributed uniformly. Specific measures shall be formulated by the State Council.
