In my case its just to know what incase of lost Service Certificate from closed company . If the company is not closed then i can request HR department to issue duplicate . If not is there anything i can do ?
Getting Duplicate for 10th , +12
The duplicate certificate issuing authority for the state is the state education board - “Directorate of Examination”
Candidates can get the Duplicate Copy of Mark List in case of loss of certificate or destroyed by flood or fire.
