The government has made it mandatory to link Aadhaar with a number of documents and financial instruments making Aadhar card as one of the most preferred proof of identity. In case you do not have Aadhaar, you can apply for an Aadhar card and get your mobile number registered in Aadhar card during the enrolment process. Once Aadhaar is linked with these instruments, the government starts transferring subsidies under various schemes such as DBT, Pahal, etc. directly in the bank account of the beneficiary and a confirmation message is sent to the registered mobile number. In case your mobile number is not registered with Aadhaar, you will not receive any such messages and will not be able to track the benefits that you are eligible to receive.
