Question: how to change mobile no in aadhar card online 2018?
Answer: The UIDAI has cancelled the online method of changing one's mobile number in the Aadhaar records. You can only do so offline by visiting your closest Aadhaar Kendra Centre. You can locate your closest centre from this link. You will have to fill an 'Aadhaar Update/Correction Form' and submit it at the centre.
