PNR stands for "Passenger Name Record" and is a unique 10-digit number assigned to every train ticket booked. It contains all the information related to your train travel, including the passengers name, age, gender, train number, coach number, seat number, and the boarding and destination stations. The PNR is generated when a passenger books a train ticket, and it serves as a reference number for the passengers journey.
On some trains, the PNR is all you need to show to the conductor, either printed out or on your smartphone or tablet. On other trains, you may need to use the PNR in a self-service ticket machine at the station to print out a paper ticket before boarding the train. It is important to note that if you print a ticket in a rail vending machine, you will have to validate the ticket prior to boarding the train.
