What AirTags Are Not Designed to Track

How an AirTag Finds Your Item’s Location

Nearby Finding vs Lost Item Finding

SituationHow It Works
When the AirTag is nearbyYour iPhone can connect to the AirTag through Bluetooth. You can use Play Sound to make the AirTag beep, or use Find Nearby if your device supports Precision Finding. Precision Finding can show distance and direction, which helps when your keys are under a couch or your wallet is inside a bag.
When the AirTag is far awayYour iPhone usually cannot connect to it directly. Instead, the AirTag waits for nearby Apple devices in the Find My network to detect its Bluetooth signal. When that happens, you may see an updated map location in the Find My app.
When no device has detected it recentlyThe app may show a Last Seen location. This means the item was detected there at that time, but it may not be the item’s live location now.
