what is cnf in railway ticket

In the context of Indian Railways, CNF stands for "Confirmed". If a passengers reservation status shows as "CNF," it means that their booking has been confirmed, and they have been assigned a seat or berth on the train. The passenger can view their coach and seat number along with the CNF status. A passenger usually gets a CNF in a train ticket if they book while there are seats available on the train, and the reservation must be done well in advance. If not, they are most likely to get a waitlisted ticket that often gets confirmed closer to the travel date. The seat number will be allocated after charting, which is usually done four hours before the train's departure.
