To get TSA PreCheck, it's most convenient to apply online at TSA.gov/precheck. After filling out an application, you'll schedule an appointment at an enrollment center to be finger-printed.
In Houston, there are five centers, including one in Bush Airport at Terminal C and one at Hobby Airport. There are also locations in La Marque, Deer Park and Freeport.
For most travelers, you'll need your passport with your legal name, or your birth certificate and driver's license together. After you're approved, you'll get your known traveler number (or KTN) and you can contact your airline to add your KTN to your profile and current reservations.
