You "opt-in" by entering your Secure Flight Passenger Data in your profile and checking the box to consent to Delta storing it and sharing it with the TSA. If you received the email about the PreCheck program, you have been preselected based on your Delta status and do not need to fill in a Known Traveler Number. Just your name, gender, and birthdate.
