I have accidently registerd with wrong adhar no. now how i can change it
You cannot change the details if you have entered your Aadhar card no# as the Id proof. And if the Aadhar card details are wrong, it cannot be changed either. Now you have to re-register with a new Email Id and mobile number and fill up the form all over again. That means a new payment all together again.
