I want to track my lost AirPods but they aren’t even listed among my devices on the app

Hello,

See this:

If your AirPods are lost

Good luck.

In addition to MrBill3's comments, the following would need to be true in order to locate your AirPods:

• Find My iPhone must have been enabled BEFORE they were lost.
• The AirPods are within range of your devices (iOS or macOS).
• They are not in their charging case.
• They are still charged.
