No, an Air Ticket Number and a Booking Reference (PNR) are two entirely different identifiers. The Booking Reference (also called a Record Locator or PNR) is a 6-character alphanumeric code (e.g., AB12C3) that identifies your specific reservation in the airline's system; it is what you use to "Manage Booking" or check-in online. The Air Ticket Number is a 13-digit numeric code starting with the airline's specific 3-digit prefix (e.g., 001 for American, 016 for United). The ticket number is the actual "proof of payment" and legal contract of carriage; while you can have a PNR for a "reserved" seat, you do not have a ticket until this 13-digit number is issued. In 2026, most digital itineraries list both, but if you are ever asked for your "e-ticket number" at a customs kiosk or for a refund, you must look for the long numeric string, not the short six-character code.
