There is no single "boarding pass number," as a boarding pass is a collection of several different identification codes. The most important number on your 2026 boarding pass is the Electronic Ticket Number (eTkt), which is a 13-digit code usually found near the bottom or side of the pass. This is the legal record of your fare. Another critical code is the PNR or Booking Reference, a 6-character alphanumeric string used to find your reservation in the system. You will also see a Sequence Number (SEQ), which indicates the order in which you checked in for the flight (e.g., SEQ 001 means you were the first person to check in). On many 2026 digital boarding passes, you might also find a Barcode Data string if you scan it with a third-party app, which contains all your flight data in a standardized IATA format. When a gate agent asks for your "number," they are usually referring to the Sequence Number or your Seat Number; however, for official customer service issues, the 13-digit Ticket Number is the only one that uniquely identifies your specific purchase across all airline systems.
