Why am I being asked to verify and link my mobile numbers with Aadhaar? 

For your own safety and the security of our country, it is legally necessary to verify identity of all mobile subscribers and link them with Aadhaar to weed out mobile numbers being operated by fraudsters, money-launderers, criminals, etc. It has been found that most criminals and terrorists get SIM cards issued in fictitious names or in someone else’s name without their knowledge and use it for committing frauds and crimes. When every mobile number gets verified with Aadhaar, the nation’s security and your safety gets boosted.
