Introduction
Air travel is increasingly becoming more secure with the introduction of various security measures such as the Transportation Security Administration’s (TSA) Precheck program and the Known Traveler Number (KTN). But what exactly are these programs and are they the same thing? This article will explore the differences between the two security programs and provide a step-by-step guide on how to sign up for either one.
What is a Known Traveler Number?
A Known Traveler Number (KTN) is a nine-digit code issued by the U.S. Department of Homeland Security that is used by travelers to access expedited security screening at airports in the United States. The KTN is linked to an individual’s personal information, such as their name, address, and date of birth.
What is TSA Precheck?
TSA Precheck is an expedited security screening program offered by the U.S. Transportation Security Administration (TSA) that allows travelers to pass through airport security checkpoints quickly and easily. To be eligible for TSA Precheck, travelers must apply online or in person and submit to a background check. Once approved, travelers receive a Known Traveler Number (KTN) which can be used when booking flights.

Exploring the Benefits of Having a Known Traveler Number vs. TSA Precheck
The Known Traveler Number (KTN) and TSA Precheck are two different programs, but they both offer similar benefits. Both programs allow travelers to bypass regular security lines at airports, saving them time and hassle. However, there are some key differences between the two programs that travelers should consider before applying.
Comparing Costs and Security Features
TSA Precheck is $85 for a five-year membership and includes access to expedited security screening at more than 200 airports in the United States. The program also requires travelers to submit to a background check and provides additional security features such as VIP lanes, enhanced passenger identity verification, and access to dedicated customer service agents.
The Known Traveler Number (KTN) does not require a fee or a background check, but it does not have all of the same security features as TSA Precheck. The KTN is only valid for one year and does not provide access to VIP lanes or dedicated customer service agents. However, the KTN does provide access to expedited security screening at most airports in the United States.
Pros and Cons of Using a Known Traveler Number or TSA Precheck
Both the Known Traveler Number (KTN) and TSA Precheck offer advantages and disadvantages. The main advantage of using the KTN is that it is free and does not require a background check. However, the KTN is only valid for one year and does not provide access to all of the same security features as TSA Precheck. On the other hand, TSA Precheck has a longer validity period and includes additional security features, but it does require a fee and a background check.
How to Sign Up for a Known Traveler Number and TSA Precheck
Signing up for either the Known Traveler Number (KTN) or TSA Precheck is easy and straightforward. Here is a step-by-step guide on how to get started:
Step 1: Gather Required Documents
Before applying for either program, travelers must first gather the required documents. For the KTN, travelers will need to provide their full name, date of birth, and contact information. For TSA Precheck, travelers will need to provide proof of citizenship or legal residency, such as a passport or driver’s license.
Step 2: Apply Online or In Person
Once travelers have gathered the required documents, they can then apply for either program online or in person. For the KTN, travelers can apply online through the Department of Homeland Security website. For TSA Precheck, travelers can apply online or in person at a designated enrollment center.
Step 3: Submit to a Background Check (If Applicable)
For TSA Precheck, travelers must submit to a background check before being approved for the program. The background check process can take up to two weeks and requires travelers to provide additional documentation, such as fingerprints and proof of residence.
Step 4: Receive Your Known Traveler Number
Once approved, travelers will receive a Known Traveler Number (KTN) for the KTN program or a TSA Precheck number for the TSA Precheck program. These numbers can be used when booking flights to receive expedited security screening at airports.
Who Should Sign Up for a Known Traveler Number or TSA Precheck?
Deciding whether to sign up for the Known Traveler Number (KTN) or TSA Precheck is a personal decision. There are a few factors to consider when making this decision, such as cost, security features, and convenience. For those who travel frequently, the added security features and convenience of TSA Precheck may be worth the cost.
