1. Understanding Your Known Traveler Number (KTN)

What exactly is a Known Traveler Number?

A Known Traveler Number (KTN) is a unique identifier assigned to individuals who have been approved for trusted traveler programs like TSA PreCheck, Global Entry, SENTRI, and NEXUS. This number allows the Transportation Security Administration (TSA) to verify your trusted traveler status, granting you access to expedited security lanes at airports. It acts as a shortcut through airport security, saving you time and reducing stress.

• TSA PreCheck: A program that allows pre-approved travelers to experience faster security screening at U.S. airports.
• Global Entry: A U.S. Customs and Border Protection (CBP) program that allows expedited clearance for pre-approved, low-risk travelers upon arrival in the United States.
• SENTRI: A CBP program that expedites the clearance process for pre-approved, low-risk travelers entering the U.S. from Mexico and Canada.
• NEXUS: A joint CBP and Canada Border Services Agency (CBSA) program that provides expedited clearance for pre-approved, low-risk travelers entering the U.S. or Canada from each other.

Where can you find your KTN?

Your KTN can be found in several places:

• Global Entry Card: If you are a Global Entry member, your KTN is printed on the back of your Global Entry card.
• TSA PreCheck Approval Letter: After being approved for TSA PreCheck, you will receive an approval letter containing your KTN.
• Online CBP Account: You can log in to your online CBP account to retrieve your KTN.
• Trusted Traveler Program Website: Depending on the program you’re enrolled in (Global Entry, TSA PreCheck, etc.), you can find your KTN on the program’s official website after logging in.

Why is having a KTN beneficial for travelers in Vietnam?

Having a KTN can be particularly beneficial for travelers visiting or residing in Vietnam for several reasons:

• Connecting Flights: Vietnam is a popular hub for international travel, and many travelers have connecting flights through U.S. airports. A KTN ensures a smoother transit experience.
• Business Travelers: For business travelers frequently traveling between Vietnam and the U.S., a KTN saves valuable time, allowing them to focus on their work.
• Expatriates: Expatriates living in Vietnam who regularly travel to and from the U.S. can benefit from the convenience of expedited security screening.
• Leisure Travelers: Tourists visiting Vietnam who plan to travel to the U.S. afterwards can start their journey with less stress and more time to enjoy their vacation.

How does Global Entry enhance travel to and from Vietnam?

Global Entry streamlines the entry process into the United States for pre-approved travelers. Upon arriving at a U.S. airport, Global Entry members can proceed to automated kiosks, present their machine-readable passport or U.S. permanent resident card, scan their fingerprints, and make a customs declaration. The kiosk issues a transaction receipt, and the traveler can proceed to baggage claim and exit the airport.

According to U.S. Customs and Border Protection (CBP), Global Entry kiosks expedite the entry process by as much as 70%, significantly reducing wait times and congestion at airports.

Benefits of Global Entry for Vietnam-bound travelers:

• Faster Entry into the U.S.: Reduces time spent in customs lines upon arrival in the United States.
• TSA PreCheck Eligibility: Global Entry members are automatically eligible for TSA PreCheck, providing expedited security screening for domestic and international flights departing from U.S. airports.
• Reduced Paperwork: Streamlines the customs declaration process, minimizing the need for manual paperwork.
• Convenience: Offers a more convenient and efficient travel experience, especially for frequent travelers.

What are the key benefits of TSA PreCheck for Vietnam-bound travelers?

TSA PreCheck offers several key benefits for travelers:

• Expedited Security Screening: Allows travelers to go through dedicated security lanes with less waiting time.
• No Need to Remove Shoes, Laptops, or Liquids: Travelers can keep their shoes, belts, and light jackets on, and they don’t have to remove laptops or liquids from their carry-on bags.
• Predictable Security Screening: Provides a more predictable and consistent security screening experience.
• Available at Over 200 Airports: TSA PreCheck lanes are available at over 200 airports across the United States.
