Social security was transferred from Nanjing to Shanghai.

1. First, get insurance in Nanjing. If you have been insured before, continue to use the previous number.

2. Go to the green channel of Shuiximen (with ID card, household registration book and Shanghai social security payment details) and issue the Nanjing social security admission notice.

3. Go to the social security center where your Shanghai unit is located and transfer your account.

Take the transfer-out account from Shanghai to your social security center for merger.

It's not clear yet. You can call 12333 for consultation.

Is this ok?
