SIXT.VN offers a range of services to make your Vietnam travel seamless, from airport transfers to hotel bookings. Let’s explore what the KTN is, where to find it, and how to use it effectively for stress-free travel. With SIXT.VN, prepare for a smooth journey with Global Entry benefits.

1. What Exactly Is a Known Traveler Number (KTN)?

The Known Traveler Number (KTN) is a nine-digit number assigned to individuals enrolled in Trusted Traveler Programs (TTP) like Global Entry and TSA PreCheck. According to the Transportation Security Administration (TSA), TSA PreCheck allows expedited screening at U.S. airports. It enables pre-approved travelers to pass through security checkpoints more quickly and efficiently. Your KTN verifies your eligibility for expedited security screening, making your airport experience smoother and faster. For international travelers, Global Entry includes TSA PreCheck benefits, adding to the convenience.

1.1. Why Is The KTN Important?

Your KTN is crucial because it links you to your trusted traveler status. According to U.S. Customs and Border Protection (CBP), Global Entry expedites clearance for pre-approved, low-risk travelers upon arrival in the United States. It allows you to use dedicated lanes at security checkpoints, which generally have shorter wait times. When you book flights and provide your KTN, airlines flag you as a trusted traveler, ensuring you receive TSA PreCheck benefits such as:

• Not removing shoes, laptops, liquids, belts, or light jackets during screening.
• Access to faster security lines.

1.2. What Are The Benefits Of Using A KTN?

Using a KTN provides numerous benefits, especially for frequent travelers. These include:

• Expedited Security Screening: The primary benefit is faster passage through airport security.
• Reduced Wait Times: Dedicated TSA PreCheck lanes typically have shorter lines than standard security lines.
• Convenience: You don’t need to remove certain items like shoes or laptops.
• Peace of Mind: Knowing you can navigate security quickly reduces travel stress.
• Global Entry Benefits: If your KTN is from Global Entry, you also get expedited U.S. customs screening when returning to the country.

1.3. Who Needs A Known Traveler Number?

A Known Traveler Number is beneficial for:

• Frequent Flyers: If you travel multiple times a year, the time saved in security lines adds up significantly.
• Business Travelers: Time is money, and expedited security helps you stay on schedule.
• Families: Traveling with children can be stressful; faster security makes the process easier.
• International Travelers: Global Entry provides benefits for both domestic and international travel.
• Individuals Seeking Convenience: Anyone who values a smoother, less stressful airport experience.

2. Is The PASSID The Known Traveler Number?

Yes, the PASSID (or “Pass ID”) on your Global Entry card is your Known Traveler Number. It’s the nine-digit number printed on the back of your card, and it serves as your unique identifier for trusted traveler programs. When asked for your KTN, this is the number you should provide.

2.1. Where Can You Find Your KTN?

You can find your KTN in several places:

• Global Entry Card: Look at the back of your Global Entry card. The nine-digit PASSID is your KTN.
• TSA Website: If you have TSA PreCheck, you can find your KTN on the TSA website after logging into your account.
• TTP Website: Log into your Trusted Traveler Programs account on the Department of Homeland Security website.
• Airline Accounts: Some airlines store your KTN in your frequent flyer profile if you’ve previously provided it.

2.2. What Does PASSID Stand For?

PASSID stands for “Passport Identification,” but in the context of Global Entry, it functions as your unique identification number within the trusted traveler system. According to CBP, the PASSID links your identity to your trusted traveler status, enabling expedited processing at airport security and border crossings.

2.3. Why Is It Called PASSID?

The term PASSID is derived from its original association with passport information. When you apply for Global Entry, your passport details are linked to this ID. Although it represents more than just passport data, the name has remained.
