Yes, in most cases the PNR number is also the booking number. There are slight differences with some airlines, but for the most part, air travelers have everything they need to check in with the PNR number.

While the terms are often used interchangeably by travelers, they are technically different in the aviation world. A PNR (Passenger Name Record) is a digital file stored in a Global Distribution System (GDS) that contains all the data for a passenger or group of passengers traveling together, including itineraries, meal preferences, and contact info. The Reservation Number (often called a Record Locator or Confirmation Code) is the specific 6-digit alphanumeric code (e.g., Z7K4L2) used to access that PNR. Essentially, the PNR is the "folder" containing all your trip details, while the reservation number is the "label" on that folder. It is important to note that if your trip involves multiple airlines, you might have one PNR but separate "Airline Confirmation Codes" for each carrier. In 2026, most airline apps will display both, but the 6-digit code is what you’ll primarily need for check-in and managing your booking.
