1. What Exactly Is A Known Traveler Number (KTN)?
Your Known Traveler Number (KTN) is a unique identifier provided to individuals approved for trusted traveler programs, primarily Global Entry and TSA PreCheck. According to the U.S. Customs and Border Protection (CBP), these programs expedite security screening for eligible travelers at U.S. airports. This nine-digit number is essential for enjoying quicker security lines and a more efficient airport experience. When booking flights to Vietnam or within the country, adding your KTN to your reservation ensures that you’re recognized as a trusted traveler, streamlining your passage through airport security checks. SIXT.VN ensures a smooth journey from arrival to departure. We offer convenient airport transfer services and advice on utilizing your KTN effectively for domestic flights.
Why Is The Known Traveler Number So Important?
The Known Traveler Number (KTN) is crucial for expedited security screening through programs like TSA PreCheck and Global Entry. Inputting this number when booking flights means you can access faster security lines. You won’t have to remove your shoes, belts, or light jackets, or take out laptops and liquids, making airport transit quicker and less stressful. According to the Transportation Security Administration (TSA), using a KTN can significantly reduce wait times at airport security checkpoints, which is especially valuable when traveling to Vietnam, where you might have connecting flights or tight schedules.
How Does The Known Traveler Number Work With TSA PreCheck And Global Entry?
TSA PreCheck and Global Entry both use the Known Traveler Number (KTN) to identify trusted travelers. TSA PreCheck is mainly for domestic flights within the U.S., offering expedited security screening at participating airports. Global Entry, on the other hand, is designed for international travelers. It provides faster clearance upon arrival in the United States, and includes TSA PreCheck benefits. When you enter your KTN while booking flights, airlines recognize your status and print a TSA PreCheck indicator on your boarding pass, directing you to the expedited security lanes. According to CBP, Global Entry members also enjoy reduced wait times when re-entering the U.S., which can be a great advantage when returning from your Vietnamese vacation.
2. Where To Find Your Known Traveler Number On Your Global Entry Card?
Locating your Known Traveler Number (KTN) on your Global Entry card is simple. The KTN, also known as your PASSID, is on the back of your Global Entry card. This nine-digit number is what you’ll need to enter when booking flights to enjoy TSA PreCheck benefits.
Locating The PASSID Number On The Back Of Your Global Entry Card
The PASSID number, which is your Known Traveler Number (KTN), is printed on the back of your Global Entry card. Just flip your card over and look for the nine-digit number labeled as “PASSID.” This number is crucial for accessing expedited security lanes at airports. Remember to keep your Global Entry card in a safe place to ensure you always have your KTN when you need it.
Accessing Your KTN Through The Trusted Traveler Program Website
If you can’t find your physical Global Entry card, you can access your Known Traveler Number (KTN) through the Trusted Traveler Program (TTP) website. Log in to your TTP account on the Department of Homeland Security website. Once logged in, you should find your PASSID or KTN listed on your account dashboard. This digital access ensures that you always have your KTN available, even if you don’t have your physical card with you.
3. Applying For A Global Entry Card To Get A Known Traveler Number
Applying for a Global Entry card is a great way to obtain a Known Traveler Number (KTN). This process involves several steps, including creating a Trusted Traveler Program (TTP) account, completing the application, paying the fee, and attending an interview. Global Entry provides expedited entry into the U.S. and includes TSA PreCheck benefits.
Step-By-Step Guide To Applying For Global Entry
Applying for Global Entry involves several steps:

Alternative Ways To Obtain A Known Traveler Number
While Global Entry is a popular method, there are alternative ways to obtain a Known Traveler Number (KTN). TSA PreCheck provides a KTN for expedited security screening on domestic flights. Additionally, some U.S. Customs and Border Protection (CBP) programs, such as NEXUS and SENTRI, also provide a KTN. Each of these programs requires an application process, including a background check and an interview. Depending on your travel needs, one of these alternative programs might be a suitable option.
4. Adding Your Known Traveler Number To Existing Flight Bookings
Adding your Known Traveler Number (KTN) to existing flight bookings is a straightforward process that ensures you receive TSA PreCheck benefits. You can add your KTN either online through the airline’s website or by contacting their customer service. This step is crucial for a smoother airport security experience.
Steps To Add Your KTN Online Through The Airline Website
To add your Known Traveler Number (KTN) online through the airline’s website, follow these steps:

Contacting The Airline’s Customer Service To Add Your KTN
If you prefer not to add your Known Traveler Number (KTN) online, you can contact the airline’s customer service. Call the airline’s customer service number and provide them with your booking details and KTN. The representative will add your KTN to your reservation. Ensure that the TSA PreCheck indicator is on your boarding pass after the KTN is added. This method is useful if you have any difficulties adding the KTN online or if you prefer speaking directly with a customer service representative.
When Can You Add Your Known Traveler Number To A Flight Booking?
You can add your Known Traveler Number (KTN) to a flight booking at any point before your flight. It is best to add it as soon as possible after booking to ensure that your TSA PreCheck benefits are applied. Airlines typically allow you to add or update your KTN until check-in. If you forget to add it before check-in, you may be able to add it at the airport check-in counter. Adding your KTN early ensures a smoother airport experience.
5. Understanding The Expiration And Renewal Of Your Known Traveler Number
Your Known Traveler Number (KTN) does expire, typically after five years. Understanding the expiration and renewal process is essential for maintaining your TSA PreCheck and Global Entry benefits. Renewing your KTN on time ensures uninterrupted access to expedited security screening.
How Long Is Your Known Traveler Number Valid?
