Shanghai social security accumulation fund transferred to Hangzhou.

As long as you have been insured in Shanghai before and now you are insured, the social security will be automatically merged and accumulated. Because everyone has only one social security account, it is only because the regions are different, so there is no merger and accumulation in different regions.

For social security in Hangzhou, if you want to transfer to Shanghai:

You can go to the Shanghai social security department to handle the acceptance letter after enrolling in Shanghai (please consult the Shanghai social security department in detail if your situation meets the acceptance policy), and then go to the Hangzhou social security department to handle the transfer formalities with the acceptance letter, and transfer the social security to Shanghai for merger.

Or, you can temporarily ignore Hangzhou social security and transfer the relevant social security from other places to places where you receive retirement wages before retirement.

The difference between transfer and non-transfer is whether the funds in the personal account of Hangzhou medical insurance clinic can be used, and the others have no effect.
