How many social security cards does a person have?

Legal analysis: A person has only one social security account, but he can apply for a social security card according to different places of study or work. In other words, a person can have multiple social security cards, but generally only pay once, so only the one that pays can be used normally. If social security has been paid in multiple places, the previously paid social security can also be merged through social security transfer procedures.

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.
