Social security has not been transferred in for a long time after it was transferred out.

Legal analysis: If the social security transfer slip is transferred out but not transferred in, it means that after you left the previous company, the company stopped paying social security for you, and has handled the employee increase and decrease insurance in the social security center, which proves that you no longer work in the original company and the insurance relationship has been transferred out from the original company. Not transferred means that after you left your original work unit, you didn't find an acceptable work unit and no unit accepted your insurance relationship. If you find a good company, do you want to get insurance after the probation period? You need to ask your current work unit yourself. If you plan to be a flexible employee or individual, you can pay the insurance premium yourself, but you must go to the social security center to apply for a personal payment certificate.
