Open Find My
Use another Apple device or visit iCloud.com/find and sign in with the Apple Account associated with your missing iPhone. Select the device to view its available location information.
Play a Sound
If the iPhone appears nearby, use Play Sound to help locate it. The device may need to be online for some actions to work.
Turn On Lost Mode
If you cannot find it, use Lost Mode when available. This can lock the device and let you display contact information on its screen.
Protect Your Account
If you suspect theft, review your Apple Account security and contact your mobile carrier if necessary. Do not share verification codes or your device passcode with anyone claiming to have found it.
If You Cannot Recover It
Follow Apple's official guidance for a missing device. Erasing it remotely may be an option, but it should be considered carefully because it can affect your ability to locate the device afterward.
