The Telecom Regulatory Authority of India (TRAI) via a letter dated May 16, 2017, has authorised the use of Aadhaar based e-KYC authentication by Internet Service Providers for the purposes of providing broadband and internet connections. This process had already been authorised and operationalised for new as well as existing subscribers of mobile connections (via letters dated September 16, 2016 and March 23, 2017 respectively). However, the TRAI is yet to come out with an appropriate format of the Customer Application Form, for the purpose of operationalising this process of ISPs. Source
