What TSA PreCheck Is and How It Works

TSA PreCheck is a trusted traveler program run by the Transportation Security Administration. The program lets certain passengers move through airport security checkpoints more quickly at U.S. airports. Instead of waiting in standard security lines, PreCheck members use separate, shorter lanes where the screening process is streamlined.

When you use TSA PreCheck, you keep your shoes, belt, and light jacket on while going through security. You can also leave your laptop and liquids bag in your carry-on luggage. Metal detectors, rather than full-body scanners, are typically used for PreCheck passengers. These changes mean the whole process takes less time, often just a few minutes compared to 20 or 30 minutes in regular lines.

The program operates at more than 200 U.S. airports. Major hubs like Atlanta, Denver, Los Angeles, and New York all have PreCheck lanes. Even smaller regional airports increasingly offer the service. When you travel internationally and return to the United States, you can use PreCheck at U.S. airports during your return journey.

TSA PreCheck requires a background check and an in-person interview at an enrollment center. The program costs $78 to $85 for a five-year membership, though the exact price varies slightly by location. Some credit cards, airline frequent flyer programs, and employer benefits cover the cost as a perk for cardholders or members.

Understanding how PreCheck actually works helps you know what to expect during enrollment and when you travel. The program focuses on making the security experience faster and less disruptive, not removing security measures entirely. All PreCheck passengers still go through security screening—it is simply a more streamlined process.

Practical Takeaway: PreCheck works by allowing trusted travelers to use faster security lanes with fewer clothing and item restrictions. You will still be screened, but the process is designed to take less time. The program operates at hundreds of U.S. airports and costs $78 to $85 for five years of membership.

Who May Be Eligible for TSA PreCheck

TSA PreCheck is open to U.S. citizens and lawful permanent residents. To proceed with enrollment, you must be at least 18 years old. The program accepts applications from people living anywhere in the United States, including all 50 states, U.S. territories, and Washington, D.C.

The TSA conducts a background check as part of the enrollment process. This background check includes criminal records, immigration status, and security databases. Most people who have no serious criminal history and maintain valid immigration status can proceed. The TSA's website and enrollment centers provide detailed information about factors that might affect your background check results.

Military members on active duty may have different pathways to PreCheck. Some military personnel receive TSA PreCheck benefits as part of their service. Military families should check with their branch's personnel office or the official TSA website for military-specific information.

Children under 18 can travel with a PreCheck parent or guardian, though they do not need their own membership. If a child has their own PreCheck membership, they can use it independently at age 18.

The TSA maintains detailed information about who may not be granted PreCheck. This includes people with certain criminal convictions, unresolved immigration issues, or security concerns. The official TSA website lists specific crimes and circumstances that may prevent enrollment. If you have questions about your particular situation, TSA enrollment centers can discuss your circumstances before you pay the fee.

Practical Takeaway: U.S. citizens and lawful permanent residents who are 18 or older may explore TSA PreCheck enrollment. Background checks examine criminal history and immigration status. The TSA website provides information about factors that might affect the background check, and enrollment centers can answer questions about your specific circumstances before you commit to the program.

The Enrollment Process: What to Expect

The TSA PreCheck enrollment process involves two main steps: an online registration and an in-person appointment at an enrollment center. The process typically takes about 10 to 15 minutes at the center, though the entire enrollment from start to finish may take a few weeks.

First, you create an account on the TSA PreCheck website or through an approved enrollment partner's site. You provide basic personal information, including your name, date of birth, and contact information. You also answer questions about your background. This online portion is free and takes about 10 minutes. After you complete it, you receive a confirmation that you can bring to your in-person appointment.

Next, you schedule an appointment at an enrollment center near you. Enrollment centers are located at airports, travel agencies, and other locations across the country. When you book your appointment, you choose a date and time that works for you. Many centers have multiple appointments available each day, and some offer evening or weekend hours.

At your appointment, a TSA official or authorized representative reviews your documents and confirms your identity. You will need to bring a valid form of identification, such as a passport, driver's license, or military ID. You will also provide your fingerprints, which are used for background check purposes. The representative collects payment at this time (around $78 to $85, depending on your location).

After your appointment, the TSA processes your background check, which usually takes 2 to 4 weeks. Once approved, you receive a Known Traveler Number (KTN) by email. You use this number when making flight reservations and at airport security checkpoints. Many people receive their KTN and can start using PreCheck within a month of their appointment.

Practical Takeaway: Enrollment involves an online registration (free, about 10 minutes) and an in-person appointment (about 15 minutes). You need a valid ID and must provide fingerprints. After approval, you receive a Known Traveler Number to use on flight bookings and at security. The total timeline from appointment to approval is typically 2 to 4 weeks.

Finding Enrollment Centers and Scheduling Your Appointment

More than 380 enrollment centers operate across the United States, making it relatively straightforward to locate one near your home or workplace. Enrollment centers are found at major airports, but also at smaller regional facilities, postal locations, law enforcement offices, and private agencies like travel companies.

The official TSA PreCheck website has a search tool where you enter your ZIP code or city name, and the tool shows all nearby enrollment centers. Each listing includes the center's address, hours of operation, and a link to schedule an appointment directly. Some centers allow you to book appointments online up to several weeks in advance, while others may require a phone call.

Appointment availability varies by location. Popular centers in large cities may have wait times of a few weeks, especially during peak travel seasons like summer or the holidays. Rural or less-trafficked areas sometimes have shorter wait times. If your nearest center has a long wait, you may consider a center in a neighboring town or city, since you can enroll anywhere in the country.

When you search for a center, pay attention to the hours listed. Some centers operate during standard business hours (9 a.m. to 5 p.m., Monday through Friday), while others offer extended hours including evenings or Saturday appointments. This flexibility means you can often find a time that fits your schedule without taking time off work.

After you complete your online registration, you can proceed directly to scheduling. The system asks for your preferred location and date. You receive a confirmation with your appointment details, a reference number, and instructions on what to bring. Most people receive this confirmation by email within a few minutes. Keep this confirmation and bring it to your appointment.

Practical Takeaway: The TSA website's search tool helps you find nearby enrollment centers by entering your location. You can book appointments online at most centers for dates weeks in advance. Availability varies, but extended evening and weekend hours are often offered. Keep your appointment confirmation and bring it with your identification to your enrollment visit.
