Shanghai social security personal account

Yes, in Shanghai, one ID card only corresponds to one personal account. No matter which company you work in, the unit manager will handle related business, and your payment record is in the same personal account, which does not involve the transfer of personal account. With your ID card, you can check the payment status in the social insurance management centers of all districts and counties. I suggest you apply for an online personal password then, and you can check it yourself on the social security service online in the future.
