I could not see all my previous company services in the service history when I login to my UAN. I have transferred (Manual transfer) my PF accumulations to the subsequent companies whenever i change my job. That time there was no UAN system. When I joined in the current company I reconfimred with respective PF offices that my previous PF amounts were transferred and remitted to my existing UAN. There was no entry observed with the names of those previous companies in the passbook as well. When I enquired, PF officials told me that history of previous companies details are not visible in the passbook, as there was no UAN system at that time and assured the previous services were added to the existing UAN . Is it true ? If so, do I still need to obtain any scheme certificate pertaining to my previous services (around 4.9 Yrs of first company + 3.1 Years of second company) at the time of retirement to apply pension. Now I am with my existing company for the last 18 yrs.
