Why does the company require a personal medical insurance certificate for 3-5 years when joining the company?

The reason for this requirement is to examine whether the professional experience in the resume is false.

In this certificate, the medical insurance is paid by the original unit, and the computer number, ID number, starting and ending time of enrollment and payment amount of the social security applicant are specified in detail, including the accumulated payment period of medical insurance. Medical insurance vouchers must be printed by the social insurance computer system and stamped with the official seal of the Social Security Bureau.

The new company can't query the social security records of employees. If the company requires social security certificate, the main purpose is to transfer social security. It should be noted that if you have not participated in any work before, or your previous unit has not paid social security and has not paid any social security experience, you can explain this situation to the company without providing social security certificates.
