Airtag Lost Mode

Losing an important item like your keys or wallet can be stressful. Fortunately, if you have an Apple AirTag attached to the item, you can use Lost Mode in the Find My app to help locate it.

What is AirTag Lost Mode?

AirTag Lost Mode allows you to mark an AirTag as lost in Apple’s Find My network. This enables Apple devices around the world to help detect the AirTag’s location and notify you when found.

When Lost Mode is activated, you can enter a phone number and message. If someone finds your AirTag, they will see these details if they tap it to their iPhone or NFC-enabled Android phone.

Lost Mode locks the AirTag to your Apple ID until you disable it. This prevents others from connecting to your AirTag if lost.

Benefits of Using Lost Mode

Using Lost Mode with AirTag offers several benefits for finding lost items:

  • Increased Visibility: Marks the AirTag as lost in Apple’s vast Find My network of nearly 1 billion active devices. Dramatically increases visibility.
  • Anonymous and Private: The tracking process is encrypted and anonymous. Your identity and AirTag location data remain private. For more on how AirTag tracking privacy works, see this article on AirTags detecting as “moving with you”.
  • Precision Finding: iPhone 11 or newer can use AR, camera and sensors for directionally aware finding.
  • Sound Alerts: Play a sound on the AirTag to help locate when nearby.
  • NFC Tap: Someone who finds your AirTag can tap it on their iPhone or NFC Android device to see your message.
  • Notifications: Get notified when your lost AirTag is located by the network.
