If you’re new to TSA PreCheck or Global Entry, you may be wondering what a Known Traveler Number (KTN) is, how it works, and why there’s a KTN box when booking flights, but there isn’t one for your TSA PreCheck or Global Entry number. Here’s what you should know about your KTN.
Your Known Traveler Number is your membership number with a Trusted Traveler Program. This number is what allows you to access TSA PreCheck security lanes and Global Entry lanes (depending on which Trusted Traveler Program you join).
To acquire a Known Traveler Number, you must participate in one of the Trusted Traveler Programs. These are:
Global Entry and TSA PreCheck are by far the most popular options in the U.S. The NEXUS and SENTRI programs also provide a Known Traveler Number, though these programs are much less commonly used in the U.S.
Many premium credit cards will reimburse you for the application fee for either Global Entry or TSA PreCheck (including American Express, Capital One, Chase, and Citi, which all provide cards that offer an application fee reimbursement).
The Amex Platinum reigns supreme for luxury travel, offering the best airport lounge access plus generous statement credits, and complimentary elite status.
When it comes to cards that offer top-notch benefits, you’d be hard-pressed to find a better card out there than The Platinum Card® from American Express.
Make no mistake — the Amex Platinum card is a premium card with a premium price tag. With amazing benefits like best-in-class airport lounge access, hotel elite status, and tremendous value in annual statement credits, it can easily prove to be one of the most lucrative cards in your wallet year after year.
This card is ideal for business travelers who enjoy luxury travel and are looking for a card loaded with benefits!
The Business Platinum Card® from American Express is a premium travel rewards card tailored toward business owners who are frequent travelers with a high number of annual expenses.
When you factor in the large number of perks that the card offers like the best airport lounge access at over 1,400 lounges, along with tons of annual credits, it’s easy to see why this card can is a top option for frequent traveling business owners.
Hot Tip: Check to see if you’re eligible for a huge welcome bonus offer of up to 170,000 points with the Amex Business Platinum. The current public offer is 120,000 points. (This targeted offer was independently researched and may not be available to all applicants.)

Get 2x miles plus some of the most flexible redemptions offered by a travel credit card!
As a frequent traveler with excellent credit, you’re always on the lookout for a credit card that comes with all the bells and whistles. And the easier it is to understand, the better!
The Capital One Venture Rewards Credit Card is one of the most popular rewards cards on the market. It’s perfect for anyone in search of a great sign-up bonus, high rewards rates, and flexible redemption options.
Since several cards offer this benefit, consider the other benefits of your credit card options before you choose one. Look at the points they earn, trip delay protection, purchase protection, elite status, or airport lounge access.
If your priority is earning tons of valuable (and transferable!) points, you might choose the Chase Sapphire Reserve card. It earns 5x points on air travel and 10x points on hotels and car rentals when you purchase travel through Chase Ultimate Rewards, 10x points on Lyft (through March 2025), 3x points on all other travel, and it comes with a Priority Pass Select membership for lounge access. You’ll also receive a $300 travel credit that is automatically applied to your first $300 in travel purchases each cardmember year (this includes taxis, Uber, Lyft, train tickets, flights, hotels, and more).
If airport lounge access and elite status are your top priorities, the Amex Platinum card and Amex Business Platinum card provide world-class lounge access, including Centurion Lounges and Delta Sky Clubs (when flying Delta), on top of a Priority Pass Select membership upon enrollment. Cardholders also receive elite status with both Hilton Honors and Marriott Bonvoy upon enrollment. To top it off, you’ll earn 5x Membership Rewards points when booking flights directly with an airline.
And for travelers who value simplicity in earning and redeeming their rewards along with a reasonable annual fee, consider the Capital One Venture X card. It earns 2x Capital One miles on all purchases and comes with the lowest annual fee among the most popular premium credit cards.
Whichever card you choose, all you have to do is use it to pay for the Global Entry or TSA PreCheck application fee, and you’ll automatically be reimbursed.
Hot Tip: You can find your PASSID (also known as your Known Traveler Number) on the back of your Global Entry, NEXUS, or SENTRI card.
If you only have TSA PreCheck, log in to the Trusted Traveler Program website to access your PASSID/Known Traveler Number. If you lose your Global Entry, NEXUS, or SENTRI card, you can use the Trusted Traveler Program site to find the number.
While it might not be apparent at first, you’ll be happy to know that your TSA PreCheck or Global Entry number is, in fact, your Known Traveler Number. Simply enter your Known Traveler Number in the appropriate field when booking your flight. This can also be done later — even at the check-in desk at the airport.
The vast majority of the time, you do not need to carry your Global Entry card to access the airport’s TSA PreCheck or Global Entry lanes. That said, there have been some recent reports of travelers being asked to show their physical card. This appears to happen most at airports that allow travelers with Global Entry to preclear security, especially for flights departing from Canada. It also may happen when entering the U.S. by car via NEXUS or SENTRI lanes.
Hot Tip: Unlike when returning from most countries, if you want to access Global Entry lanes when returning from Canada, you will need your physical Global Entry card with you.
As anyone who’s been through airport security knows, it can be a frustrating hassle. To expedite the screening process at many U.S. airports, TSA PreCheck access provides a much better experience. If you are returning to the U.S. from an international destination, Global Entry can make getting through customs a breeze.
If you mainly travel within the U.S., you might think that you only need to get TSA PreCheck — this is understandable, considering the fee is $78 compared to $100 for Global Entry.
However, a Global Entry membership also provides access to TSA PreCheck. When you account for the application fee reimbursement offered by several credit cards, why wouldn’t you go ahead and get Global Entry? With the right card, the impact on your wallet is the same — neither should cost you a dime!
By getting Global Entry, you can enjoy a quicker security experience when boarding flights in the U.S. If you decide to travel abroad, you can take comfort in the fact that returning to the U.S. will be easy.
Airports are becoming busier by the year, so having access to TSA PreCheck and Global Entry is vital for quicker and smoother security screenings. With so many credit cards offering to reimburse you for the application fee, there is no excuse not to have a Known Traveler Number.
Whether you get TSA PreCheck or Global Entry, you’ll be all set for a better airport experience — just enter your PASSID/Known Traveler Number when booking your flight.

Always a fan of flying, it was only natural that Spencer was drawn to finding a way to improve the travel experience.
Like many, he started this journey searching for cheap flights to take him around the world. This was fun for a while, but Spencer was intrigued by the idea of flying in business and first class!
Throwing himself into what became an extensive research project, Spencer spent 3-4 hours per night learning everything he could about frequent flyer miles over the course of several months (he thinks this is normal). He runs Straight to the Points, an award-seat alert platform.
