How that can even happen? The admit cards are released only to have the Roll number and the name of the exam center. So you should check the admit card very well, it must be mentioned. Usually every year the Roll number is provided beside the Application Number. If you still don't get it then I would recommend you to contact the authorities in the help line numbers (The general Enquiry and Help line number is 011-22240112 ).
