what is pnr number in train ticket

PNR stands for "Passenger Name Record" and is a unique 10-digit number code that is provided for all train ticket bookings made via Indian Railways. It is a record in the database of Indian Railways computer reservation system (IR-CRS) against which journey details for a passenger, or a group of passengers are saved. PNR number is generally printed at the top left corner of the printed tickets, and in case of an E-Ticket, it is mentioned at the top in a separate cell. Passengers personal information like name, age, gender, etc. is saved in the database against this reference number. It includes columns to store booking status and current status of the ticket. The PNR number contains two parts, and the first three digits specify the area from where the ticket is booked. The starting digit of the PNR number indicates from where the train would start. The PNR number is crucial for the journey, and it helps to get updates on train timing, journey dates, coach number, and seat number. In case of any difficulties during the journey, such as ill behavior or disgusted services on the train, a complaint can be filed to Indian Railways with the 10-digit code on the ticket.
