What about the upgrade certificate of Tianjin Social Security Bureau?

You can go to the social security bureau window to handle it.

I go to the window to handle it, and I will provide my original ID card when I handle it, and others will provide the original ID cards of the applicant and the agent when I handle it.

Social security certificate refers to the payment list issued by the Social Security Bureau, which details the computer number, ID number, starting and ending time of participation, payment amount, etc. of the social insurance applicant.
