1987 joined the work, 1988 transferred to the original single. How to inquire about the social security paid by the original unit?

1987 did not have social security, and 1992 began to have social security payment regulations.

92 years ago, the length of service was regarded as the payment period. As long as the length of service is recorded in your file, the social security bureau will make a determination.

For those who work in advance, the social security payment period includes the deemed payment period (92 years ago) and the actual payment period (92 years later). If you have any objection to the fixed number of years, you can go to the unit to check the files first. If the previous length of service record is not true, you can find the superior department in charge of the previous unit (in the past, state-owned or collective units were all managed by districts and counties or a bureau)
