You cannot switch or upgrade between programs. If you are a TSA PreCheck Application Program member and would like to join CBP’s Global Entry Program because you frequently travel internationally, you must enroll with Global Entry as a new applicant and pay their enrollment fee. The cost to enroll in Global Entry is $120 for five years of membership.
Current TSA PreCheck members may be eligible for expedited Global Entry application processing. TSA PreCheck members need to provide CBP their Known Traveler Number (KTN) when completing the application. The KTN is 9 or 10 digits long, can be a combination of numbers and letters, and begins with TT, TE or AC. Use the KTN look up tool to find your TSA PreCheck Application Program KTN. TSA PreCheck members must complete the Global Entry application process before their TSA PreCheck membership expires or they will not receive TSA PreCheck screening until their Global Entry application is approved.
If you have a KTN, but did not apply via the TSA PreCheck Application Program, you are not eligible for this expedited application process.
