How to lock and unlock Aadhaar Card online and prevent misuse?

Aadhaar is now turning to be one of the most important KYC document. Hence, protecting your privacy from any misuse is also important. Let us see how to lock and unlock Aadhaar Card online and protect from misuse.

This is the actually foolproof process and completely eliminated the process of submitting hard copies and may be misused.

Once someone does an e-KYC using your Aadhaar number, then immediately you will receive an email and SMS message to your phone registered with them. The email looks like below.

  2. Hello,
    Facing a peculiar problem for aadhar unlock. A few months ago I had locked my biometric aadhar details through the website and now would like to unlock it. However I am facing a peculiar situation. I have my mobile no. (9xxxxxxxxxx) registered with my Adhaar card. The mobile no. is an AIRCEL (Mobile operator) no. However recently AIRCEL have stopped their service in my hometown and henceforth for the whole country. Any calls or SMS have therefore stopped coming through my no. (9xxxxxxxxxx). Thus for unlocking my Aadhar I am unable to receive or see any OPT (One-time-password) being send for unlocking. I am in a dire situation as I cannot buy a new SIM or port this no. ((9xxxxxxxxxx)) to any other operator since all these require Aadhar card verification, in my case, which remains locked. I have my email at yahoo also registered in the Aadhar site but OPT is not being received in my email, it is only send to my mobile no. (9xxxxxxxxxx). Any aadhar enrolment centre personel is unable to help me in this situation. Don’t know what to do . I have a alternate JIO no. which is active and can receive calls and SMS which I can register with Adhaar if my account gets unlocked. . Any suggestions would be very helpful.
    – Regards
