1. Understanding the Known Traveler Number (KTN)
What exactly is a Known Traveler Number?
A Known Traveler Number (KTN) is a unique identifier issued by the U.S. Department of Homeland Security (DHS) to individuals approved for Trusted Traveler programs such as TSA PreCheck, Global Entry, NEXUS, and SENTRI. It’s essentially a code that verifies your eligibility for expedited security screening at airports. According to the Transportation Security Administration (TSA), possessing a KTN can significantly reduce your wait time at airport security checkpoints.
- TSA PreCheck: This program allows pre-approved travelers to go through expedited security lanes at U.S. airports. You generally don’t have to remove your shoes, laptops, liquids, or light jackets.
- Global Entry: This program provides expedited customs processing for pre-approved, low-risk travelers arriving in the United States from abroad. It also includes TSA PreCheck benefits.
- NEXUS: This program is designed for expedited border clearance between the United States and Canada.
- SENTRI: This program provides expedited entry into the United States from Mexico and Canada.
