meri 12 aur 10 ke marksheet kho gai hai aur mujhe apna roll number finder Khanna hai

If you have lost your Class 10 and Class 12 marksheets and need your roll number, first check your previous school records, examination forms, admit cards, result documents, fee receipts, DigiLocker account, registered email and SMS messages.

You can also contact your school or the concerned examination board. They can help you retrieve your examination details using information such as your name, date of birth, father's/mother's name and year of examination.

Once the roll number is recovered, you can apply for duplicate marksheets/certificates through the respective board's prescribed procedure.
