Luggage trackers typically combine short-range and wide-area technologies. Short-range tags use Bluetooth (and sometimes ultra-wideband) for nearby locating, while wide-area trackers rely on GPS, Wi‑Fi, cellular networks, or cell-tower triangulation to report a remote location.

Some tags are designed for a specific phone ecosystem and won’t work with all smartphones. Cellular GPS trackers require a cellular data connection and often need a SIM or provider subscription to report locations through the maker’s app.

Attachment methods vary by device: common options include adjustable straps and keychain rings for tags, while some GPS trackers advertise powerful magnets for quick attachment to metal surfaces.

Some luggage tags are described as water-resistant, and at least one GPS tracker in the results is rated IP67 for stronger waterproof protection.

Common app features include real-time notifications and audible chimes to help find a tag, turn-by-turn directions to the tag’s location, sharing access with others, location history and trip logs, and virtual geo-fence boundary alerts with push notifications.

Bluetooth locating range varies by tag and environment. Examples list indoor ranges around 10–20 meters and outdoor ranges around 20–50 meters for short-range connection-based locating.
