What is pnr number

Last updated: April 1, 2026

Quick Answer: A PNR number (Passenger Name Record) is a unique booking reference code assigned by airlines to each reservation. It allows passengers and airlines to track, modify, and manage flight bookings.

Key Facts

Overview

A PNR (Passenger Name Record) number is a crucial booking reference in the airline industry. This six-character alphanumeric code is automatically generated when a passenger makes a flight reservation and serves as the primary identifier for that booking throughout the entire travel journey.

Structure and Format

A PNR number consists of six characters, typically combining letters and numbers (for example: 2K9Z8W). The system is standardized across the aviation industry, allowing different airlines and travel agencies to recognize and access the same reservation record. Each PNR is unique to a specific booking and passenger combination.

Finding Your PNR Number

Passengers can find their PNR number in several locations:

Uses and Functionality

The PNR number enables multiple functions including checking booking status and flight details, modifying passenger information, changing flight dates or times, checking in online, and accessing seat selection. Passengers can also use their PNR to receive flight notifications, manage baggage, and contact customer service for assistance. Airlines use PNR data for customer identification, seat allocation, revenue management, and tracking passenger movements.

Security and Privacy

Airlines maintain strict security protocols for PNR data. Passengers should protect their PNR number as it contains personal and booking information. Most airlines allow PNR access through their website or app when combined with a passenger's last name or email address. Government agencies in some countries also monitor PNR data for security and customs purposes.
