Known Traveller Number (KTN): A Complete Guide

Travelling can be stressful, especially when you’re in long queues at the airport. Fortunately, there is a solution to this. 

The Known Traveller Number (KTN) allows you to speed through security checks. 

If you travel frequently, having a KTN can make the process faster and less stressful. 

In this article, we’ll explain what a Known Traveller Number is, how to get one, and how it can benefit you.

What is a Known Traveller Number (KTN)?

A Known Traveller Number is a unique identification number that allows travellers to enjoy expedited security screening and faster travel processes. 

It is issued to individuals who have been approved for trusted traveller programmes, such as TSA PreCheck, Global Entry, NEXUS or SENTRI. 

These programmes are designed to reduce wait times and make airport experiences more efficient by providing access to dedicated, faster lanes for security checks. 

A KTN is typically used during flight bookings and check-in to ensure eligibility for faster processing at airport security or customs. 

Having a KTN means fewer checks and a smoother travel experience, particularly for frequent travellers. 

The number is valid for a certain period, typically five years, and can be renewed. 

It is accepted by several countries, especially the United States, but may also be applicable for international flights and select airports worldwide.

How to Get a Known Traveller Number

To get a Known Traveller Number, you must first apply for a trusted traveller programme. 

The most common programmes in the United States include TSA PreCheck, Global Entry, NEXUS, and SENTRI. 

Each of these programmes has its own application process and eligibility requirements.

Choose the Programme

Select the trusted traveller programme that best suits your travel needs. 

TSA PreCheck is ideal for domestic flights, while Global Entry is useful for international travellers. 

NEXUS and SENTRI are designed for travellers crossing borders between the U.S. and Canada or Mexico.

Complete the Application

Fill out the online application form for the chosen programme. 

This typically includes personal information, travel history, and background questions.

Pay the Application Fee

Each programme requires a non-refundable fee, which can vary, depending on the programme.

Schedule an Interview

After your application is processed, you will be invited for an in-person interview. 

This interview usually involves fingerprinting and a full background check, to ensure that you are suitable for a KTN.

Approval

If you pass the interview and background check, you will be approved and issued a KTN. 

This number can then be used for expedited screening when booking flights and passing through airport security.

How Much Does it Cost to Get a Known Traveller Number?

The cost of obtaining a Known Traveller Number depends on the trusted traveller programme you choose to apply for. 

These fees are generally consistent, though they may vary slightly depending on your country of residence or the application location. 

It’s recommended to check the official programme website for the most up-to-date information on fees, payment methods, and application details.

Below are the typical fees for some of the most popular programmes:

TSA PreCheck

The application fee for TSA PreCheck is around $85. 

This fee covers a five-year membership, allowing faster screening for domestic flights.

Global Entry

Global Entry costs about $120 for a five-year membership. 

It provides expedited screening for both domestic and international flights, as well as faster processing at U.S. customs when arriving from abroad.

NEXUS

NEXUS is specifically for travellers crossing the U.S.-Canada border. 

It is around $50 to send in your application, this is paid whether or not it is approved.

SENTRI

SENTRI is designed for expedited border crossings between the U.S. and Mexico. 

The application fee for SENTRI is approximately $120 per application. 

It provides faster processing at both U.S. and Mexican customs, making it ideal for frequent travellers between the two countries.

What Countries Accept a Known Traveller Number?

The Known Traveller Number is most commonly used in the United States, but it is also accepted in several other countries. 

Here are some examples:

United States

The United States is the primary country where the Known Traveller Number (KTN) is used. 

It grants access to expedited screening through TSA PreCheck for domestic flights, as well as Global Entry for faster entry through U.S. customs for international travellers.

Canada

Canada recognises U.S. trusted traveller programmes, including Global Entry and NEXUS. 

For those with a KTN, this means expedited border entry when travelling between the U.S. and Canada, providing a quicker and more seamless experience at customs.

Mexico

Mexico also accepts Global Entry and NEXUS members with a KTN. 

This allows for expedited processing when crossing the U.S.-Mexico border and when entering Mexico from the U.S.

United Kingdom

Global Entry members with a KTN can enjoy expedited entry to the UK through the Registered Traveller Programme. 

This provides faster processing at border control for U.S. citizens entering the UK.

Other Countries

Several countries, including Australia and various European Union nations, have agreements with the U.S. that allow travellers with a KTN to access expedited screening or customs entry. 

Always check the guidelines for each country to ensure your KTN is recognised.

Known Traveller Number Benefits

There are numerous benefits to having a Known Traveller Number. 

Here are a few of the key advantages:

Expedited Security Screening

One of the primary benefits of a Known Traveller Number is access to expedited security screening. 

In the U.S., TSA PreCheck allows you to skip long security lines, making the travel experience faster and more convenient. 

This is particularly beneficial for frequent flyers, saving significant time at the airport.

Faster Border Entry

For international travellers, a KTN grants access to Global Entry, which expedites the customs process when entering the U.S. 

It also provides faster border entry in countries that recognise the programme, such as Canada, Mexico, and the UK. 

This makes returning from international trips much quicker, reducing time spent waiting in lines.

Reduced Stress

By bypassing long queues at security and customs, a KTN helps reduce the stress of air travel. 

With expedited processing, you can move through the airport with more ease and confidence, giving you more time to relax before your flight.

Convenience for Frequent Travellers

For those who travel regularly, a KTN is invaluable. 

It provides consistent access to faster screening and customs processing, making travel much more efficient, convenient, and less time-consuming.

Known Traveller Number Issues

While a Known Traveller Number offers significant benefits, there are a few potential issues to be aware of:

Limited Availability

Not all travellers are eligible for a KTN. 

Certain programmes, like Global Entry, require a thorough background check and interview process. 

Additionally, if you have a criminal record or certain disqualifying factors, you may not be able to participate in the trusted traveller programmes that issue KTNs.

Compatibility Across Airports and Countries

While many countries recognise KTNs, it’s important to note that not all airports or airlines accept them. 

Certain airports may not yet have the infrastructure for expedited security or customs processing, meaning that even if you have a KTN, you may not benefit from faster screening.

Potential Errors in the System

There are instances where travellers experience issues with their KTN not being recognised or linked properly to their airline reservations. 

This could result in being denied access to expedited screening or customs lines. 

It’s crucial to ensure your KTN is correctly added to your airline profile and booking.

Delays in Application Processing

While the application process for trusted traveller programmes is usually straightforward, there can sometimes be delays in approval or a lack of available interview slots, especially in busy areas or during peak travel times.

Conclusion

You should now have a good understanding on exactly what a Known Traveller Number is and how it can benefit you.

A Known Traveller Number is an excellent tool for those who travel frequently and want to speed up their journey through security and immigration. 

With its many benefits, such as faster security checks, access to TSA PreCheck, and Global Entry, the KTN can save you time and reduce travel-related stress. 

However, it’s essential to consider the application process, fees, and eligibility requirements before applying. 

By understanding the benefits and drawbacks of the KTN, you can decide whether it’s the right choice for your travel needs. 

Whether you travel for business or leisure, a KTN can make your journey smoother and more convenient.
