Hello aspirant .

The Supreme Court has passed a judgement on Aadhar card constitutional validity in September 2018. According to the judgement, it restricts the government from linking Aadhaar with examinations conducted by the National testing academy, NEET for medical entrance. In simple words, Aadhar card is not mandatory for NEET. You may use another document as a proof like voting card,driving license or any other government recognised documents.

If you have any other documents with your initial it wont create problem. 

Note that your name,father name,mother name should be as per class 10 marks sheet.

All the best.
