Is my known traveler number the same as my TSA PreCheck number?

A Known Traveler Number (KTN) is issued to all individuals approved to receive TSA PreCheck® expedited screening. The KTN must be added in the KTN field when booking airline travel reservations to have the TSA PreCheck® indicator appear on your boarding pass.
