Feicheng Human Resources and Social Security Bureau, I checked my old-age insurance on my mobile phone 1983 till now. How to change it to 1994 now?

Because 1994 began to implement the individual contribution system for endowment insurance, the previous personal information could not be found.

The length of service of enterprise employees before the implementation of the individual payment system for endowment insurance shall be regarded as the payment period according to the provisions of the state.

The retirement pension benefits of employees are calculated by combining the deemed payment period and the actual payment period, and the social security payment period includes the deemed payment period.

According to your description, the period from 1983 to 1993 should be regarded as the payment period, and the accumulated payment period after 94 is your pension insurance payment period.
