If you already have a BSNL landline connection, you won't need anything except the form.If you don't, you are usually asked to take a landline connection first. Then you can apply for Broadband connection over this number. But before filling up for landline, just confirm the feasibiliy and availability of BB in your area.In this case you would need following:1) Photo Identity: A) Driving License/Arms License/PAN Card or so listed on form.2) Address Proof: A) Rental Agreement copy B) Copy of latest Electricity/Water/Telephone bill of LandLord3) A PP size photo of applicant.Cheers,Vipin.
