TSID (Travel Sentry ID) is a global lost-and-found system for luggage and personal items. Each TSID tag carries a unique 12-character code and a QR code that a finder can scan to notify the owner, without ever revealing the owner's personal details.

An owner registers their TSID code for free at tsid.com, linking the tag to their contact details online rather than printing a name and address on the bag itself. If the item is lost, a finder scans the QR code or enters the code at tsid.com and leaves their own contact information. TSID then alerts the owner instantly by email and the owner decides how to arrange the item's return, their personal information is never shown to the finder.
Registration takes under a minute, covers an unlimited number of TSID tags (one for your suitcase, one for your backpack, one for your guitar case) on one free account and never expires, there are no passwords to remember and no renewal fees.
TSID is part of the largest Lost and Found network WorldTracer, used at over 2,800 airports across 214 countries, 400 airline and airport companies and supporting 14 languages. That scale is what gives a registered item a real shot at recovery rather than relying on a name tag or luck: over 10 million unique TSID accounts have been created to date.
For the end consumers, TSID turns a lost bag from a dead end into a recoverable one, without asking them to put their name and address on display for anyone to see. It also isn't limited to checked luggage: the same tag works on backpacks, electronics, cameras and effectively anything a customer wants to protect.
Beyond the recovery mechanics, brands that integrate TSID get access to a few tangible advantages:
