If you've lost or misplaced an Apple device, such as your iPhone, use the Find My app on an iPhone, iPad, or iPod touch with the latest version of iOS or iPadOS or a Mac with the latest version of macOS signed in with the same Apple ID.
For a misplaced iPhone, iPad, iPod touch, Apple Watch, Mac, AirPods product, or supported Beats product, you can also use the Find My app on a device owned by someone in your Family Sharing group, or sign in to iCloud.com/find on a web browser.
Open the Find My app.
Choose the Devices or Items tab.
Select the device or item to see its location on the map. If you belong to a Family Sharing group, you can see the devices in your group.
Choose Directions to open its location in Maps.
If you turn on Find My network, you can see your device or item's location even if it's not connected to a Wi-Fi or cellular network. The Find My network is an encrypted anonymous network of hundreds of millions of Apple devices that can help you locate your device or item.
If you don't see your device, you might not have Find My turned on. If your device is powered off, the battery has run out, or more than 24 hours has passed since its last location was sent to Apple, you can't see your device's location.
