When you travel, there are a few pieces of information you probably like to keep handy, including your frequent flyer number, your passport number and your trip confirmation number.

However, another number comes into play if you have TSA PreCheck or Global Entry: your Known Traveler Number. It's an important number that ensures access to the TSA PreCheck lanes.

Here's what to know about getting a KTN, how to find it and how to ensure it's attached to your flight reservations.

A KTN is a nine-digit code each TSA PreCheck and Global Entry member receives from the U.S. Department of Homeland Security upon approval for one of those two programs. Members of a couple of other Trusted Traveler programs get a KTN as well.

The code may be a combination of both letters and numbers. It's your identification number that proves you're a member of one of these programs and shows that you are eligible to use the TSA PreCheck lanes at U.S. airports.

Travelers with a KTN have gone through an application and screening process, and they are known and recognized as travelers by the U.S. government.

Getting a KTN is helpful for air travel because if you have one, it means you're a member of a program that gets you shorter wait times.

A KTN is your key to access the TSA PreCheck lanes. These lanes typically have shorter lines and allow members to undergo a less intrusive screening process than the standard lanes. About 99% of TSA PreCheck customers wait 10 minutes or less at security, according to the Transportation Security Administration.

There are several ways to get a KTN through different Trusted Traveler programs run by the DHS. Each program requires travelers to submit an application and go through an interview process. Those interviews generally occur in person at enrollment centers for first-time applicants, with many enrollment centers located at airports. The government is allowing virtual interviews for certain applicants, often those seeking to renew their membership.

Each program that provides travelers with a KTN has a fee, and memberships in all programs are valid for five years. Many credit cards also offer application fee credits for Global Entry or TSA PreCheck.

If you've applied for TSA PreCheck, gone through the screening process and received confirmation of your approval into the program, you'll receive a KTN from the government.

TSA PreCheck offers a fast-tracked security experience for its members. When going through the TSA PreCheck lanes, you generally won't have to remove your shoes, take laptops or liquids out of your bag, or go through the full-body scanner.

The application fee is $78 for first-time applicants.
