Is there only one social security card in the province?

Legal analysis: Yes, but only one social security card can be applied. In the same area but in different areas, the banks to which social security cards belong are different. For example, although my work unit and household registration are located in the same city, they are not in the same area, so different social security cards belong to different banks in the social security center. At present, social security is only a municipal co-ordination. If you go to work in a city, you will get a social security card. So Doka is normal and there will be no consequences. But you can't cancel it, because the social security card can only be used in the place where you buy social security, and you can't enjoy the treatment if you cancel it. It has no effect on retirement, as long as you transfer all the old-age insurance in different places to your retirement place when you are about to retire. There is no need to do anything at present.

Legal basis: Article 32 of the Social Insurance Law, if an individual is employed across the overall planning area, his basic medical insurance relationship will be transferred accordingly, and the payment period will be calculated cumulatively.
