A Known Traveler Number (KTN) is your gateway to expedited security screening, allowing you to breeze through airport security lines with ease. At TRAVELS.EDU.VN, we understand the value of a smooth and stress-free travel experience, which is why we’re here to help you understand everything you need to know about KTNs, ensuring you’re well-prepared for your next journey. Securing a KTN unlocks quicker airport navigation via TSA PreCheck lanes, granting you valuable time and reducing travel-related stress.
1. What Is a Known Traveler Number (KTN)?
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, NEXUS, or SENTRI. This number, typically nine characters long and a combination of letters and numbers, verifies your enrollment in these programs, granting you access to expedited security lanes at airports and border crossings. It proves to the Transportation Security Administration (TSA) that you have undergone a thorough background check and are considered a low-risk traveler.
Expanding on that, the KTN serves as a digital key, unlocking a smoother, more efficient airport experience. It streamlines the security process, saving you time and reducing stress. Your KTN links to your profile within the TSA and Customs and Border Protection (CBP) databases, allowing them to quickly verify your trusted traveler status. This verification ensures you can utilize dedicated TSA PreCheck lanes, experience quicker customs processing upon returning to the U.S., and enjoy other benefits associated with trusted traveler programs. TSA PreCheck members generally do not need to remove shoes, laptops, or liquids from their bags.
2. Why Should I Get a Known Traveler Number (KTN)?
Obtaining a KTN unlocks numerous benefits, primarily centered around saving time and reducing stress during air travel. The most significant advantage is access to TSA PreCheck lanes at U.S. airports. These lanes typically have shorter lines and require less intrusive screening procedures compared to standard security checkpoints. According to the TSA, approximately 99% of TSA PreCheck passengers wait less than 10 minutes in security lines.
Beyond shorter wait times, TSA PreCheck offers a more convenient screening experience. Enrolled members often don’t have to remove shoes, belts, or light jackets, and are permitted to keep laptops and liquids in their carry-on bags. This streamlined process can significantly reduce the hassle and time spent navigating airport security. For frequent travelers or those who value convenience, the benefits of a KTN are substantial. The tangible time savings and reduced stress contribute to a more enjoyable and efficient travel experience. A KTN streamlines your passage through security and validates your status as a trusted traveler.
3. How Do I Get a Known Traveler Number (KTN)?
There are several pathways to acquiring a KTN, each tied to enrollment in a specific Trusted Traveler Program managed by the Department of Homeland Security (DHS). Each program involves an application process, background check, and often an in-person interview.
- TSA PreCheck: This program focuses on expediting domestic air travel security screening. Applicants must complete an online application, undergo a background check, and attend an in-person appointment at an enrollment center for fingerprinting. The application fee is $78, and membership lasts for five years.
- Global Entry: Designed for frequent international travelers, Global Entry provides expedited customs processing upon arrival in the U.S., along with TSA PreCheck benefits. The application process is more extensive than TSA PreCheck, requiring a more detailed application and an interview with a CBP officer. The application fee is $100, and membership is valid for five years.
- NEXUS: Geared towards travelers frequently crossing the U.S.-Canada border, NEXUS offers expedited border clearance at land, air, and sea ports of entry. The application process involves background checks and interviews with both U.S. and Canadian border officials. The application fee is $50.
- SENTRI: Similar to NEXUS, SENTRI facilitates expedited entry into the U.S. from Mexico and Canada via land, air, and sea. The application process includes a background check, interview, and vehicle inspection (if applicable). The application fee is $122.25.

4. What Are the Requirements for Each Trusted Traveler Program to Get a KTN?
Each Trusted Traveler Program has specific eligibility requirements that applicants must meet to qualify for membership and obtain a KTN. These requirements typically focus on citizenship, criminal history, and immigration status.
- TSA PreCheck: Applicants must be U.S. citizens, U.S. nationals, or lawful permanent residents. Certain criminal offenses and immigration violations may disqualify applicants.
- Global Entry: Eligibility requirements are similar to TSA PreCheck, with additional scrutiny given to international travel history and any customs or immigration violations.
- NEXUS: Applicants must be citizens or lawful permanent residents of the U.S. or Canada. The program also considers factors such as criminal history, immigration violations, and customs compliance.
- SENTRI: Similar to NEXUS, SENTRI requires applicants to be citizens or lawful permanent residents of the U.S. or Mexico. The program also considers factors such as criminal history, immigration violations, and customs compliance.
It’s important to carefully review the specific eligibility requirements for each program before applying to ensure you meet the criteria. Providing false or misleading information on your application can lead to denial of membership. The application process for these programs is detailed on the DHS website.
5. How Do I Find My Known Traveler Number (KTN)?
Locating your KTN is crucial for adding it to airline reservations and ensuring you receive TSA PreCheck benefits. The location of your KTN depends on which Trusted Traveler Program granted it to you.
- TSA PreCheck: If you enrolled directly in TSA PreCheck, your KTN is printed on your approval letter or card. You can also retrieve it by logging into your TSA PreCheck account on the DHS website.
- Global Entry: Your KTN, also referred to as your PASSID, is printed on the back of your Global Entry card. It is also available in your online Global Entry account on the Trusted Traveler Program (TTP) website. PASSID usually starts with 15, 98, or 99.
- NEXUS/SENTRI: Your KTN is printed on your NEXUS or SENTRI card. It can also be found in your online TTP account.
If you’ve misplaced your physical card or approval letter, the easiest way to retrieve your KTN is by logging into your online TTP account. If you are unable to access your online account, you can contact the DHS or the specific program’s customer service for assistance.

6. How Do I Add My Known Traveler Number (KTN) to Airline Reservations?
Adding your KTN to your airline reservations is essential to ensure “TSA PreCheck” is printed on your boarding pass, granting you access to expedited security lanes. The process is straightforward and can be done during or after booking your flight.
- During Booking: When booking your flight online, you’ll typically be prompted to enter your personal information, including your name, date of birth, and KTN. Look for a field labeled “Known Traveler Number,” “KTN,” or “Secure Traveler Information.” Enter your KTN accurately in this field.
- After Booking: If you forgot to add your KTN during booking, you can still add it to your reservation through the airline’s website or mobile app. Locate your reservation using your confirmation number and last name. Navigate to the passenger information section and look for the KTN field. Enter your KTN and save the changes.
It’s recommended to add your KTN to your frequent flyer profile with each airline you fly frequently. This ensures your KTN is automatically included in all future reservations made with that airline. Always double-check your boarding pass to confirm “TSA PreCheck” is printed on it before heading to the airport.
7. What Happens If I Forget to Add My KTN to My Flight?
Forgetting to add your KTN to your flight reservation is a common occurrence, but it doesn’t necessarily mean you’ll miss out on TSA PreCheck benefits. Most airlines allow you to add your KTN to your reservation even after you’ve completed the booking process.
The easiest way to add your KTN is by visiting the airline’s website or using their mobile app. Locate your reservation using your confirmation number and last name. Navigate to the passenger information section and look for the KTN field. Enter your KTN and save the changes.
If you’re unable to add your KTN online, you can try adding it at the airport check-in counter. Present your KTN and boarding pass to the agent, and they should be able to add it to your reservation. However, keep in mind that adding your KTN at the airport is not always guaranteed, as it depends on the airline’s policies and the agent’s ability to modify your reservation.
8. What If My Boarding Pass Doesn’t Say TSA PreCheck Despite Having a KTN?
Even if you’ve added your KTN to your reservation, there’s a chance your boarding pass might not display the “TSA PreCheck” indicator. Several factors can cause this, including technical glitches, errors in your reservation information, or random audits by the TSA.
- Verify Information: First, double-check that your KTN, name, and date of birth are entered correctly in your airline profile and reservation. Even a minor discrepancy can prevent TSA PreCheck from being applied.
- Contact Airline: If your information is correct, contact the airline to ensure your KTN is properly associated with your reservation. They may be able to resolve the issue or provide further guidance.
- TSA Recheck: If you’re already at the airport, visit the airline’s check-in counter or a TSA help desk. Explain the situation and provide your KTN. They may be able to reprint your boarding pass with the TSA PreCheck indicator.
Even if your boarding pass doesn’t say “TSA PreCheck,” you can still try your luck at the TSA PreCheck lane. Sometimes, the TSA agent may allow you to enter the lane after verifying your KTN and identity.

9. Can Children Use TSA PreCheck With Me If They Don’t Have a KTN?
One of the perks of TSA PreCheck is that certain family members can accompany you through the expedited security lanes, even if they don’t have their own KTN.
According to the TSA, children aged 12 and under can accompany a parent or guardian with TSA PreCheck through the expedited lanes. This means that if you have TSA PreCheck and are traveling with your young children, they can enjoy the same expedited screening benefits as you, without needing their own KTN.
However, keep in mind that this policy only applies to children aged 12 and under. Children aged 13 and older are required to have their own KTN to access TSA PreCheck lanes. If your teenager doesn’t have TSA PreCheck, they’ll need to go through the standard security lanes, even if you have TSA PreCheck.
10. What Are the Benefits of Global Entry Over TSA PreCheck to Obtain a KTN?
While both Global Entry and TSA PreCheck provide expedited security screening, Global Entry offers additional benefits that may make it a more attractive option for frequent international travelers.
- Expedited Customs: The primary advantage of Global Entry is expedited customs processing when returning to the U.S. from abroad. Global Entry members can use automated kiosks to quickly clear customs and immigration, bypassing long lines and paperwork.
- TSA PreCheck Included: Global Entry membership automatically includes TSA PreCheck benefits. This means that Global Entry members can enjoy expedited security screening at U.S. airports, in addition to expedited customs processing.
- Wider Applicability: Global Entry is valid at more airports and border crossings than TSA PreCheck. If you frequently travel internationally, Global Entry provides a more comprehensive solution for expedited travel.
- Conditional Approval: CBP sometimes offers conditional approval for Global Entry upon initial review of your application.
The application fee for Global Entry is $100, slightly higher than the $78 fee for TSA PreCheck. However, if you plan to travel internationally at least once a year, the added benefits of Global Entry make it a worthwhile investment.
11. How Does a KTN Help with International Travel?
While a KTN primarily facilitates expedited security screening for domestic flights within the U.S., it can also indirectly benefit international travelers.
If you have Global Entry, NEXUS, or SENTRI, your KTN grants you access to expedited customs processing when returning to the U.S. from abroad. This can save you significant time and hassle, especially during peak travel periods. Global Entry members can use automated kiosks to quickly clear customs and immigration, bypassing long lines and paperwork.
Even if you don’t have Global Entry, having a KTN can still be helpful for international travel. Some foreign countries have reciprocal agreements with the U.S. that allow TSA PreCheck members to use expedited security lanes at their airports. Check with the specific airport or airline to see if this benefit is available.

12. What Is the Cost of Obtaining a Known Traveler Number (KTN)?
The cost of obtaining a KTN depends on which Trusted Traveler Program you enroll in. Each program has its own application fee, which is non-refundable, even if your application is denied.
- TSA PreCheck: The application fee for TSA PreCheck is $78. Membership is valid for five years.
- Global Entry: The application fee for Global Entry is $100. Membership is valid for five years.
- NEXUS: The application fee for NEXUS is $50. Membership is valid for five years.
- SENTRI: The application fee for SENTRI is $122.25. Membership is valid for five years.
Many credit cards offer reimbursement for the application fees for TSA PreCheck or Global Entry as a cardholder benefit. Check with your credit card issuer to see if this benefit is available. Certain travel credit cards offer credits for TSA PreCheck or Global Entry.
13. How Long Is a Known Traveler Number (KTN) Valid?
A KTN is valid for the duration of your membership in the Trusted Traveler Program that granted it to you. Memberships in TSA PreCheck, Global Entry, NEXUS, and SENTRI are all valid for five years.
Prior to the expiration of your membership, you’ll need to renew your enrollment to maintain your KTN and continue enjoying expedited security benefits. The renewal process is similar to the initial application process, requiring you to submit an online application and undergo a background check.
It’s important to renew your membership before it expires to avoid any gaps in coverage. If your membership expires, you’ll lose access to TSA PreCheck lanes and other expedited security benefits until you complete the renewal process. Set a reminder to renew your KTN well in advance of its expiration date.
14. Can My Known Traveler Number (KTN) Be Revoked?
Yes, your KTN and membership in a Trusted Traveler Program can be revoked if you violate the program’s terms and conditions or engage in certain prohibited activities.
The TSA and CBP have the authority to revoke your membership if you provide false or misleading information on your application, violate security regulations at airports or border crossings, or engage in criminal activity.
Common reasons for revocation include:
- Providing false or incomplete information on your application.
- Violating airport security regulations, such as attempting to bring prohibited items through security checkpoints.
- Being convicted of a crime, particularly a felony or a crime involving dishonesty or moral turpitude.
- Violating customs or immigration laws.
If your membership is revoked, you’ll lose your KTN and will no longer be eligible for TSA PreCheck or other expedited security benefits. You may also be prohibited from reapplying for membership in the future.
15. What Should I Do If My Known Traveler Number (KTN) Is Lost or Stolen?
If your Global Entry, NEXUS, or SENTRI card is lost or stolen, it’s important to report it to the CBP immediately. You can report a lost or stolen card online through the Trusted Traveler Program (TTP) website or by contacting the CBP INFO Center.
Reporting a lost or stolen card is important to prevent unauthorized use of your KTN and to protect your identity. Once you’ve reported the loss or theft, the CBP will deactivate your card and issue you a replacement card.
If you only have TSA PreCheck and your KTN is lost, you can retrieve it by logging into your TSA PreCheck account on the DHS website or by contacting the TSA. While you don’t need a physical card for TSA PreCheck, it’s still important to protect your KTN to prevent unauthorized use.
16. Can I Use My Known Traveler Number (KTN) for Cruises or Other Forms of Travel?
While KTNs are primarily designed for air travel, they can sometimes be used for other forms of travel, such as cruises.
Some cruise lines participate in the TSA PreCheck program, allowing passengers with a KTN to enjoy expedited security screening before boarding the ship. Check with your cruise line to see if they participate in the TSA PreCheck program and if you can use your KTN for expedited screening.
KTNs are generally not applicable for other forms of travel, such as trains or buses. However, it’s always best to check with the specific transportation provider to see if they offer any expedited security benefits for Trusted Traveler Program members.
17. Is It Possible to Appeal If My Application for a KTN Is Denied?
Yes, if your application for TSA PreCheck, Global Entry, NEXUS, or SENTRI is denied, you have the right to appeal the decision.
The appeal process varies depending on which program denied your application. Generally, you’ll need to submit a written appeal to the agency that denied your application, explaining why you believe the decision was incorrect and providing any supporting documentation.
The agency will review your appeal and make a final determination. If your appeal is successful, your application will be approved, and you’ll receive your KTN. If your appeal is denied, you may have the option to file a further appeal or seek legal assistance.
18. Are There Any Age Restrictions for Obtaining a Known Traveler Number (KTN)?
There are no minimum age restrictions for obtaining a KTN. Children of any age can apply for TSA PreCheck, Global Entry, NEXUS, or SENTRI, as long as they meet the eligibility requirements.
However, as mentioned earlier, children aged 12 and under can accompany a parent or guardian with TSA PreCheck through the expedited lanes, even if they don’t have their own KTN. Children aged 13 and older are required to have their own KTN to access TSA PreCheck lanes.
If you plan to travel frequently with your children, it may be worthwhile to enroll them in TSA PreCheck or Global Entry, even if they are under the age of 13. This will ensure that they can always access expedited security lanes, regardless of whether they are traveling with you.
19. What Are Some Common Mistakes to Avoid When Applying for a Known Traveler Number (KTN)?
Applying for a KTN can be a complex process, and it’s easy to make mistakes that could delay or even deny your application. Here are some common mistakes to avoid:
- Providing Inaccurate Information: Double-check all the information you provide on your application, including your name, date of birth, address, and citizenship status. Even a minor error can cause delays or denial.
- Failing to Disclose Criminal History: Be honest and upfront about any criminal history, even if you think it’s minor. Failing to disclose criminal history can be grounds for denial.
- Not Reviewing the Eligibility Requirements: Before applying, carefully review the eligibility requirements for the specific program you’re interested in. Make sure you meet all the criteria before submitting your application.
- Missing the Interview: If an interview is required, make sure you schedule it promptly and attend it on time. Missing the interview can result in your application being denied.
- Not Renewing on Time: Set a reminder to renew your membership before it expires. Allowing your membership to expire can result in a loss of benefits and a delay in reapplying.
By avoiding these common mistakes, you can increase your chances of a smooth and successful application process.
