Hello candidate,

First of all you must know that in order to make your aadhar card is not mandatory for the the individual to provide his personal mobile number but it can work with any mobile number which might be of your parents as well. But, while going for bank account processing it's better that you provide your personal mobile number if you are going to use it for your personal use because most of the required Bank information such as OTP and other details for KYC processing are also done through mobile number which year using on your personal basis so it would be easier for you.

Hope you found it helpful.
