Sir,
As Aadhar Number is made compulsory to link with Mobile Number to continue working of Mobile Number. The telecom Company have started the Process of Aadhar linking through IVRS but they are insisting on that Aadhar Number should be of same State as that of Mobile Number.
Aadhar Number is a unique number which does not limits to any state. So I have the following questions
1. Is Aadhar Number and Mobile Number is of same State is compulsory for linking as per government law
2. My Aadhar Number belongs to Bihar as my Mobile Number belongs to West Bengal. As per telecom companies I could not link both. So does it means that I will never link My Mobile Number with my Aadhar Number.
3. If Aadhar Number and Mobile Number of same states is not compulsory then why the telecom companies are demanding it.
Thanking you.
