No, your known traveler number (KTN) is not the same as your passport number. Your KTN is a unique identification number assigned to you under the Trusted Traveler Programs like TSA PreCheck or Global Entry. It is used to access expedited security screenings. Your passport number, however, is issued as part of your passport documentation by your country's government and serves as your identity on international travels. To use the benefits of expedited screening, ensure your KTN is added to your flight reservations.
