I found an AirPod in a parking lot. How do I find owner?

You are unable to find the owner. The owner does have the ability to track them with different options depending on the model. The location of the AirPods will be transmitted to the owner whenever there is another Apple device within Bluetooth range. It may be best to leave them in a inconspicous location where there is traffic from other devices so the user can find them. They are also able play a sound on the device when they are close enough to make locating easier.

You don’t.

You should turn it into the lost and found of the facility or the police.
