Are you a globetrotter planning a trip to Vietnam and wondering where to find your Known Traveler Number (KTN) on your Global Entry card? SIXT.VN is here to help simplify your travel experience. Finding your KTN is crucial for accessing expedited security lanes and enjoying smoother journeys. Let’s explore how to locate this essential number and make the most of your travel benefits, ensuring a seamless adventure in Vietnam.
1. What is a Known Traveler Number (KTN) and Why Does It Matter?
A Known Traveler Number (KTN) is a unique identifier assigned to individuals who have been pre-approved for trusted traveler programs like Global Entry, TSA PreCheck, or NEXUS. According to research from the U.S. Customs and Border Protection (CBP) in 2023, using a KTN can significantly reduce wait times at airport security checkpoints. This number is essential because it allows you to access expedited security lanes, making your travel experience faster and more convenient.
1.1. What is the Purpose of a KTN?
The primary purpose of a KTN is to verify that you are a trusted traveler who has undergone a thorough background check. According to the Transportation Security Administration (TSA), travelers with a KTN experience shorter wait times and faster screening processes at airport security checkpoints. By entering your KTN when booking flights, you signal to the airline and TSA that you are eligible for TSA PreCheck benefits.
1.2. Who Needs a Known Traveler Number?
A Known Traveler Number is particularly beneficial for frequent travelers, business travelers, and families who want to streamline their airport security experience. If you regularly fly within the United States or internationally, having a KTN can save you valuable time and reduce stress at the airport. Enrollment in programs like Global Entry or TSA PreCheck requires a comprehensive background check, making you a pre-approved, low-risk traveler.
1.3. Benefits of Having a Known Traveler Number
Having a Known Traveler Number offers several key benefits:
- Expedited Security Screening: Access to TSA PreCheck lanes, which typically have shorter wait times.
- No Need to Remove Shoes, Belts, or Light Outerwear: Streamlined screening process for quicker passage through security.
- Keep Laptops and Liquids in Your Bag: More convenient screening experience as you don’t need to unpack these items.
- Global Entry Benefits: If your KTN is from Global Entry, you also get expedited customs clearance when entering the United States.
According to CBP data, Global Entry members spend significantly less time in customs lines compared to regular travelers.
2. Where to Find Your Known Traveler Number on Global Entry Documents
Finding your Known Traveler Number is straightforward once you know where to look. It is typically located on various documents and membership cards associated with trusted traveler programs.
2.1. On Your Global Entry Card
The most common place to find your KTN is on your Global Entry card. The number, also known as a PASSID, is printed on the back of the card. According to U.S. Customs and Border Protection (CBP), the PASSID serves as your KTN when booking flights and accessing TSA PreCheck benefits. It is crucial to ensure this number is accurately entered to receive the benefits of your trusted traveler status.
2.2. On Your TSA PreCheck Approval Letter
If you applied directly for TSA PreCheck, your KTN will be on the approval letter you received from TSA. According to the TSA, this letter confirms your enrollment and provides the necessary information to access expedited screening. Keep this letter in a safe place for future reference.
2.3. On Your GOES Account
Your KTN can also be found on your GOES (Global Online Enrollment System) account. This is the online portal where you initially applied for Global Entry. According to CBP, your GOES account contains all your membership details, including your KTN. Accessing your account online is a convenient way to retrieve your KTN if you have misplaced your card or approval letter.
2.4. On Your NEXUS or SENTRI Card (If Applicable)
If you are a member of NEXUS or SENTRI, your membership card also contains your KTN. The number is usually printed on the back of the card. According to CBP, NEXUS and SENTRI programs provide expedited border crossing between the United States, Canada, and Mexico. The KTN on these cards can also be used for TSA PreCheck benefits.
