Know how to lock Aadhaar number through SMS
In order to further strengthen your privacy and security, UIDAI has introduced a feature to lock and unlock your Aadhaar Number. After locking your Aadhaar number, authentication cannot be performed using your Aadhaar number. In that case, you may use your Virtual ID to perform authentication.
With this Aadhaar lock feature, misuse of your Aadhaar number by anyone else will be prevented. Unlocking your Aadhaar number will resume the use of Aadhaar number for authentication. You can lock/unlock your Aadhaar online or through SMS.
In case your message is not being sent, check if your SMS service is working properly. In case of any issue with respect to the SMS not being sent, contact your telecom service provider. It may be a case of bad network or non-functioning SMS service or low balance etc
