A Passenger Name Record (PNR) is a unique database entry in a Computer Reservation System (CRS) that stores travel itinerary details for a passenger or group. Initially introduced by Railways for interlining (multi-carrier journeys), PNR standards were set by IATA/ATA under AIRIMP guidelines. While formats vary by CRS, most systems follow similar structures for seamless data exchange.
For Indian Railways travelers, checking IRCTC PNR status is crucial to confirm ticket details like booking status, seat/berth number, and train schedule. This helps avoid last-minute confusion.
