That’s a valuable information. Just thought of updating it further.

After submitting the re-verification request, you will get an acknowledgement from your telecom operator. In case of BSNL, the subscriber will receive the following message:

Your request for Re-verification of Customer Record for Mobile Number with Aadhar E-KYC registered.

To confirm SMS “REV YES”.

To cancel “REV NO” to 53734 within 3 days.

No response will be treated as accepted.

You can just ignore the message or else send confirm SMS. Interestingly, you’ll get the same message for the next 2 days.
