TRAVELS.EDU.VN understands that navigating airport security can be stressful, and having a Known Traveler Number (KTN) is key to a smoother experience. While the terms might seem interchangeable, your KTN is not quite the same as your TSA PreCheck membership itself, but it’s the golden ticket to unlocking expedited screening benefits. In this guide, we will clarify the nuances of KTN and how it relates to TSA PreCheck, Global Entry, and other trusted traveler programs, ensuring your journey is as seamless as possible. Let’s dive into travel tips, security check procedures, and TSA guidelines.
1. What Exactly Is a Known Traveler Number (KTN)?
A Known Traveler Number (KTN) is a unique identifier assigned to individuals who have been approved for a Trusted Traveler Program. This number is crucial for accessing expedited security screening at airports. Programs like TSA PreCheck, Global Entry, NEXUS, and SENTRI all provide a KTN upon approval. Think of it as your personal shortcut through airport security, saving you time and hassle.
1.1. Purpose of a Known Traveler Number
The primary purpose of a KTN is to allow the Transportation Security Administration (TSA) to verify your trusted traveler status. When you enter your KTN during airline booking or provide it to the agent at the check-in counter, the airline transmits this information to the TSA. The TSA then verifies your eligibility for expedited screening. This verification process ensures that only pre-approved travelers receive the benefits of TSA PreCheck.
1.2. How to Obtain a Known Traveler Number
Obtaining a KTN involves applying to one of the Trusted Traveler Programs offered by the Department of Homeland Security (DHS). The most common programs include:
- TSA PreCheck: Focuses on expedited security screening at U.S. airports.
- Global Entry: Provides expedited clearance for international travelers entering the United States.
- NEXUS: Designed for travelers between the U.S. and Canada.
- SENTRI: Facilitates expedited entry for travelers entering the U.S. from Mexico.
Each program has its own application process, eligibility requirements, and fees. Once approved, you will receive a KTN that you can use when booking flights.
1.3. Who Needs a Known Traveler Number?
A KTN is beneficial for frequent travelers who want to save time and avoid long security lines at the airport. If you value convenience and efficiency, obtaining a KTN is a worthwhile investment. It’s particularly useful for:
- Business travelers who frequently fly for work.
- Families with children who want a smoother travel experience.
- Individuals who prefer to avoid the stress of traditional security screenings.
2. Is the Known Traveler Number (KTN) the Same as TSA PreCheck?
No, the Known Traveler Number (KTN) is not exactly the same as TSA PreCheck, but it is an integral part of the program. The KTN is the unique identifier assigned to you once you are approved for TSA PreCheck or another trusted traveler program.
2.1. Distinguishing Between KTN and TSA PreCheck
Think of TSA PreCheck as the program itself, and the KTN as your membership number within that program. TSA PreCheck is the service that provides expedited security screening, while the KTN is the number you use to access those benefits. When you enroll in TSA PreCheck, you undergo a background check and provide fingerprints. Once approved, you receive a KTN. This number is then used when booking flights to ensure you receive the TSA PreCheck benefits.
2.2. Understanding TSA PreCheck Benefits
TSA PreCheck offers numerous benefits that make air travel more convenient:
- Expedited Screening: Allows you to go through security lines faster.
- No Removal of Shoes, Belts, or Light Outerwear: Reduces the hassle of preparing for security checks.
- Laptop and Liquids Stay in Bag: Simplifies the screening process by eliminating the need to unpack your carry-on items.
- Dedicated Security Lanes: Provides access to shorter, dedicated security lanes.
According to the TSA, travelers with TSA PreCheck spend an average of 5 minutes or less in security lines.
2.3. How to Use Your KTN for TSA PreCheck
To use your KTN for TSA PreCheck, you must enter it correctly when booking your flight. Here’s how:
- Online Booking: Look for the “Known Traveler Number” or “Redress Number” field on the airline’s booking page.
- Airline Profile: Save your KTN in your airline profile for automatic application to future bookings.
- Check-In: If you forgot to add your KTN during booking, you can usually add it during online check-in or at the airport check-in counter.
Entering your KTN ensures that the TSA PreCheck indicator appears on your boarding pass, granting you access to the expedited security lane.

3. How to Add Your Known Traveler Number to Airline Reservations
Adding your Known Traveler Number (KTN) to airline reservations is a straightforward process that ensures you receive TSA PreCheck benefits. Whether you’re booking online, managing your airline profile, or checking in at the airport, there are several ways to include your KTN.
3.1. Adding KTN During Online Booking
When booking your flight online, the airline’s booking page typically includes a field labeled “Known Traveler Number” or “Redress Number.” This is where you should enter your KTN. Ensure that you enter the number correctly to avoid any issues with your TSA PreCheck eligibility.
3.2. Saving KTN in Your Airline Profile
For frequent travelers, saving your KTN in your airline profile is a convenient way to ensure it’s automatically applied to future bookings. Most airlines allow you to store your KTN in your account settings. Here’s how to do it:
- Log In: Log in to your airline’s website or mobile app.
- Account Settings: Navigate to your account settings or profile section.
- Personal Information: Look for a section to update your personal information, such as name, date of birth, and contact details.
- Known Traveler Number: Find the field for “Known Traveler Number” or “Trusted Traveler Number” and enter your KTN.
- Save Changes: Save the changes to your profile.
Once your KTN is saved, it will automatically be added to all future reservations made through your account.
3.3. Adding KTN During Check-In
If you forgot to add your KTN during booking or to your airline profile, you can usually add it during online check-in or at the airport check-in counter.
- Online Check-In: During the online check-in process, you should be prompted to enter your KTN.
- Airport Check-In: If checking in at the airport, provide your KTN to the airline agent. They can add it to your reservation at that time.
Adding your KTN at check-in ensures that your boarding pass is printed with the TSA PreCheck indicator.
3.4. Verifying KTN Application
After adding your KTN to your reservation, it’s essential to verify that it has been correctly applied. Check your boarding pass for the TSA PreCheck indicator, which is usually a logo or text that says “TSA PreCheck.” If you don’t see this indicator, double-check that your KTN was entered correctly and contact the airline if necessary.
4. What to Do If Your KTN Is Not Working
Even with a valid Known Traveler Number (KTN), there may be times when you don’t receive the TSA PreCheck benefits. Understanding the common issues and how to resolve them can help you ensure a smoother travel experience.
4.1. Common Reasons for KTN Issues
Several reasons can cause your KTN not to work:
- Incorrect Information: The most common reason is entering your KTN incorrectly during booking or in your airline profile.
- Name Mismatch: The name on your airline reservation must exactly match the name on your TSA PreCheck application.
- Expired Membership: Your TSA PreCheck membership may have expired.
- Random Security Measures: Even with TSA PreCheck, you may occasionally be subject to standard security screening as part of random security measures.
- Airline Participation: Not all airlines participate in TSA PreCheck.
- System Errors: Sometimes, technical glitches in the airline or TSA systems can prevent your KTN from being recognized.
4.2. Checking Your TSA PreCheck Status
The first step in troubleshooting KTN issues is to check your TSA PreCheck status. You can do this online through the DHS website. This will confirm whether your membership is active and that the information on file is correct.
4.3. Correcting Information and Renewing Membership
If you find that your information is incorrect or your membership has expired, you’ll need to take corrective action.
- Correcting Information: If your name, date of birth, or other personal information is incorrect, contact the TSA to update your records.
- Renewing Membership: If your TSA PreCheck membership has expired, you can renew it online. Renewing before your membership expires can help ensure uninterrupted access to TSA PreCheck benefits.
4.4. Contacting TSA or Airline for Assistance
If you’ve checked your status, corrected any errors, and ensured that your membership is active, but you’re still not receiving TSA PreCheck benefits, contact the TSA or the airline for assistance.
- TSA Contact Center: You can contact the TSA Contact Center at (866) 289-9673 or fill out an online form on the TSA website.
- Airline Customer Service: Contact the airline’s customer service department to ensure that your KTN is correctly associated with your reservation.
4.5. Understanding Random Security Measures
Even with TSA PreCheck, you may occasionally be subject to standard security screening. This is due to random security measures implemented by the TSA. These measures are unpredictable and apply to all travelers, regardless of their trusted traveler status.
5. Global Entry vs. TSA PreCheck: Which Is Right for You?
When it comes to expedited airport security, Global Entry and TSA PreCheck are two popular options. Understanding the differences between these programs can help you determine which one best suits your travel needs.

7. Maintaining Your Trusted Traveler Status
Once you’ve obtained a Known Traveler Number (KTN) through a Trusted Traveler Program, it’s essential to maintain your status to continue enjoying the benefits of expedited security screening. Here are some key steps to ensure your membership remains active and in good standing.

One of the most important aspects of maintaining your Trusted Traveler Status is keeping your information up-to-date. This includes your name, address, contact details, and passport information.
