I want to jump ship. I work in Shanghai. I changed companies. Excuse me, do I need to go through those procedures for my social security?

1, if your previous company paid you social security in Shanghai, don't transfer in the same city. Therefore, it is enough for your current unit to go through the renewal formalities directly. Don't transfer.

2. If your previous company paid you social security in other places, you need to transfer it to a place before you can merge. The method of transfer is: first, take your ID card to the social security agency in the insured area to issue a proof of payment for old-age insurance. After you are insured in Shanghai, take this payment voucher to the social security agency where the company is located to apply for transfer in other places. Individuals and companies have already handled it.

Of course, if you don't plan to settle in Shanghai in the future, you can stay here for the time being. It is ok to change jobs before retirement.
