Can the original social security card still be used after enrolling in different places?

Legal analysis: it cannot be used, but the original social security relationship can be transferred to the new social security in different places. After the merger, the original social security information will be transferred to the new social security in different places. If there is a balance in the original social security personal pension account and personal medical insurance account, it will also be transferred to the new remote personal pension insurance account and personal medical insurance account. After the transfer is successful, the original social security card or medical insurance card will be invalid.

Legal basis: Article 57 of the Social Insurance Law of People's Republic of China (PRC) stipulates that the employing unit shall, within 30 days from the date of its establishment, apply to the local social insurance agency for social insurance registration with its business license, registration certificate or unit seal. The social insurance agency shall, within fifteen days from the date of receiving the application, examine and issue the social insurance registration certificate.

Where the social insurance registration items of the employing unit are changed or the employing unit is terminated according to law, it shall, within 30 days from the date of change or termination, go to the social insurance agency to handle the change or cancellation of social insurance registration.

The market supervision and management department, the civil affairs department and the organization management organ shall promptly inform the social insurance agency of the establishment and termination of the employing unit, and the public security organ shall promptly inform the social insurance agency of the birth, death, household registration, migration and cancellation of the individual.
