Hi aspirant,

Your question is not quite clear but I assume that you want to correct your DOB in AADHAR card. In that reference I would like to tell you that there are 15 documents authorized by government for use as Birth proof which includes:

• Passport
• Birth Certificate
• PAN Card
• SSLC Book/ Certificate
• A certificate on UIDAI format or ID Card having photo and Date of Birth or DOB duly signed and issued by a Government authority
• Photo ID card with Date of Birth, issued by Recognized Educational Institution
• Certificate of Date of Birth issued by Group A Gazetted Officer
• Government Photo ID Card or Photo Identity Card issued by PSU with DOB
• Central or State Pension Payment Order
• Central Government Health Service Scheme Photo Card or Ex-Servicemen Contributory Health Scheme Photocard
• Marksheet issued by any Government Board or University
• Certificate of Identity with Name, DOB and Photo issued by Recognized Educational Institution signed by Head of Institute on UIDAI format
• School Leaving Certificate or SLC, School Transfer Certificate or TC with Name and Date of Birth
• Certificate of identity with Name, DOB and Photograph issued by Employees’ Provident Fund Organisation or EPFO on UIDAI format
• Extract of School Records issued by Head of School with Name, Date of Birth and Photograph

So following that you can use the marksheet or SLC as a proof to change DOB instead of admit card which is not part of above mentioned list.

Hope it helps!!
