Will social security be merged automatically?

Hello, I'm glad to answer your questions. Social security will not merge automatically. In the same city, your ID number is social security account number. No matter how many companies you pay, they are all in the social security account. You don't have to pay it twice, and it can be displayed in the social security system of the same city. If social security in different places cannot be merged automatically, the reason is that social security cards are not connected to the whole country and cannot be used and merged in two places. Social security transfer and merger process in different places: Step 1: Prepare relevant materials (1) social security cards (if not, reissue them first) and ensure that there is a balance. 2) Certificate of resignation, and ensure that the company has put your social security in a "deactivated" state. 3) Personal ID card Step 2: Go to the Social Security Service Center of the Social Security Bureau where social security is currently purchased to handle the social security transfer-out business. Step 3: After entering the social security bureau, you don't need to queue up to get the number, just follow the prompts at the social security self-service terminal.
