What is a Known Traveler Number?

A Known Traveler Number (KTN) is a unique identification number that is assigned to individuals who are part of a trusted traveler program, such as Global Entry, TSA PreCheck, or NEXUS.

It is a convenient way for travelers to expedite their airport security screening process and enjoy a more seamless travel experience.

Definition and purpose of a KTN

A KTN serves as a form of identification that allows participating airlines and transportation security agencies to verify a traveler’s eligibility for expedited security screening.

It is a 9-digit number that is linked to the traveler’s personal information, such as their name, date of birth, and passport information.

By providing their KTN when booking flights or going through airport security, travelers can benefit from shorter lines, reduced wait times, and a more efficient travel experience.

Who needs a Known Traveler Number?

Anyone who frequently travels domestically or internationally can benefit from having a Known Traveler Number.

It is especially useful for individuals who value their time and want to avoid long security lines at airports.

Travelers who frequently fly for business, leisure, or other purposes can greatly benefit from enrolling in a trusted traveler program and obtaining a KTN.

Additionally, individuals who often travel with their families or in groups can also benefit from having a KTN.

By providing their KTN to the airline or during the booking process, it is possible for all members of a traveling party to be eligible for expedited screening, making the journey more convenient for everyone involved.

Programs associated with KTNs

There are several trusted traveler programs that are associated with Known Traveler Numbers. The most well-known program is Global Entry, which is administered by U.S. Customs and Border Protection (CBP).

Global Entry allows pre-approved, low-risk travelers to avoid the traditional passport control lines when entering the United States and provides access to expedited security screening through TSA PreCheck.

Another program is TSA PreCheck, which is administered by the Transportation Security Administration (TSA).

TSA PreCheck offers expedited security screening for domestic flights within the United States.

By providing their KTN, travelers can enjoy benefits such as keeping their shoes on, leaving laptops in their bags, and going through dedicated security lanes.

NEXUS is another trusted traveler program that is available to Canadian and U.S. citizens.

It allows expedited processing for travelers entering the United States or Canada at designated air, land, and marine ports of entry.

It is important to note that each trusted traveler program has its own application process and eligibility requirements.

Travelers interested in obtaining a Known Traveler Number should visit the official websites of the respective programs for more information and to start the application process.

What Global Entry provides

Global Entry provides several benefits to its members. Firstly, members can use automated self-service kiosks at select airports to complete their entry into the United States.

U.S. citizens, U.S. lawful permanent residents, and citizens from certain other countries are eligible to apply.

The application process involves submitting an online application, paying a non-refundable fee, and attending an in-person interview at a Global Entry Enrollment Center.

During the interview, your fingerprints will be taken, and you will have the opportunity to ask any questions you may have about the program.

Getting your Global Entry card

The card contains your Known Traveler Number (KTN), which is a unique identification number assigned to each member.

You can find your KTN on the back of your Global Entry card, and it is also printed on the paper receipt you receive after your in-person interview.
