"TSA 002" refers to one of the master key codes used by the Transportation Security Administration to open and inspect locked luggage without damaging the lock. If you look closely at your luggage lock and see the "TSA 002" engraving next to the keyhole, it signifies that it is a Travel Sentry® Approved lock. There are several of these codes (e.g., 001 through 007), each corresponding to a specific master key held only by authorized security agents. This system allows you to secure your bag with a combination or key lock while still allowing the TSA to perform mandatory safety inspections. If a security officer needs to open your bag and sees the "002" mark, they use their "TSA 002" master tool to unlock it, inspect the contents, and then relock it, leaving your property secure. If you use a non-TSA-approved lock that security needs to open, they are legally permitted to cut or break the lock to gain access, which is why seeing the "TSA 002" (or similar) mark on your luggage is essential for international travel.
