Sir, your PNR number is printed on your ticket, whether it is an e-ticket or physical ticket purchased at counter ! All you have to do is look at the PNR number given there ! I don't see your problem. Plus, the ticket itself will say your position: Waitlist/RAC or confirmed berth giving coach and seat number.. so where is the problem? Please clarify so that we can help you. You DONT HAVE TO REMEMBER YOUR PNR NUMBER. YOU HAVE TO REMEMBER TO CARRY YOUR TICKET !!!!! THAT CONTAINS YOUR PNR NUMBER. Good wishes.
