The full form of PNR is Passenger Name Record. The Indian railway network is one of the largest in the world, transporting over a million passengers and tonnes of freight from one site to another every day. The railways have devised a PNR system for passengers who book a reserved ticket in order to maintain such a system and ensure its optimal operation. So, PNR is a computer reservation system database that stores itinerary details of people or groups of passengers travelling through trains, buses, railways, or domestic and international aeroplanes. It is an electronic barcode that contains the traveller’s date, time, boarding location, and destination. The booking reference, commonly known as the PNR, is the Indian Railways’ internal identifier for your train reservation within its computer systems.

When a traveller books a trip, a PNR is created in the computer reservation system of the trip expert or travel site client. This is often one of the Global Distribution Systems. However, if the booking is done lawfully through a carrier, the PNR may also be in the database of the service provider’s CRS. This PNR is also known as the traveller’s Master PNR, along with the associated schedule or itinerary. A record locator then stores the PNR in the appropriate database. When the holder of the Master PNR does not supply travel segments, duplicates of the PNR data are transmitted to the CRSs of the service provider that will provide transportation. CRSs open copies of the initial PNR in their database to deal with the sections of the passenger’s journey that it is capable of handling. One of the GDSs that allows PNR sharing facilitates the CRS for these various transporters. Although PNRs were initially exclusively available for air travel, these carrier frameworks can now be used for accommodation, hotel, vehicle rental, air terminal exchanges, and train travel.
Difference between PNR and Itinerary:
A travel itinerary is a schedule of events related to planned travel that includes destinations to be visited at specific times and modes of transportation. PNR is a specific word for a few or all components of a timetable (referred to as segments*). In other words, a schedule may contain a number of PNRs. PNRs are made up of at least one segment. A PNR can be booked in one or more computer reservation systems (CRS) via several methods (for example, global Distribution Systems – GDS). To get to these distinct PNRs in different systems, a Super PNR (also known as a master itinerary) is required. A Super PNR is similar to a PNR in that it can contain multiple PNRs from the same PNR.
