Use Find My to locate your iPhone from someone else's device
You can find your missing iPhone using another iPhone, iPad, or Mac through the Find My app. This works because Find My uses your Apple ID to locate all your devices on a map, whether you own them or not. The person lending you their device just needs to open Find My, sign in with their Apple ID, and switch to viewing your devices — or you can sign in with your own Apple ID on their device.
The fastest way is to ask the person to open Find My on their iPhone, tap the Devices tab at the bottom, and look for your iPhone in the list. Your location appears on the map immediately. If your iPhone is powered off or has no internet connection, Find My shows the last known location instead.
This method works even if your iPhone is locked, in silent mode, or has location services turned off — Find My uses a separate system that works independently of those settings.
Key Takeaways
- Find My shows your iPhone's location on a map when you sign in with your Apple ID on another person's device.
- The person lending you their iPhone can see your device location without signing in with your own Apple ID — they just need to open Find My and tap Devices.
- Find My works even if your iPhone is powered off, in silent mode, or has location services disabled.
- If your iPhone is offline, Find My displays the last location it reported before losing connection.
- You can make your iPhone play a sound, lock it remotely, or erase it from the Find My app if you cannot retrieve it.
Sign in with your own Apple ID on their device
If you want to use the other person's iPhone to search for yours, the simplest approach is to sign in with your own Apple ID. Open the Find My app on their device — it comes built into every iPhone. Tap Sign In and enter your Apple ID email and password.
Once you are signed in, tap the Devices tab at the bottom of the screen. You will see a list of all devices linked to your Apple ID, including your missing iPhone. Tap your iPhone's name to see its location on the map. A blue dot marks the exact spot where your device last reported its location.
After you find your iPhone, sign out of Find My on their device by tapping your profile picture in the top right corner, scrolling down, and tapping Sign Out. This removes your Apple ID from their phone and protects your privacy.
Let them search using their own Apple ID
The other person does not need to sign in with your Apple ID to help you search. They can open Find My on their device, tap Devices, and look for your iPhone in the list — but only if you have added them as a family member or trusted contact in your Apple ID settings.
If you have not set that up yet, the fastest option is to sign in with your own Apple ID on their device (as described above). However, if you regularly share location with family members through Family Sharing, they can see your devices without you signing in on their phone.
To check if someone is set up as a family member, open Settings on your iPhone, tap your name at the top, then tap Family Sharing. You will see a list of people who can view your location. If the person lending you their device is not listed, you will need to sign in with your own Apple ID on their phone to search.
What to do if your iPhone is offline or powered off
Find My still shows your iPhone's location even if it is powered off, has no cellular connection, or is in airplane mode. However, the location displayed is the last place your iPhone reported before going offline — it may be several hours or even days old depending on when the device last connected to the internet.
If your iPhone has been offline for a long time, the map will show an approximate area rather than a precise location. This is still useful for narrowing down where to search, especially if you lost it at home, at work, or in a specific neighborhood.
Once your iPhone comes back online — either because someone turns it on or it regains a network connection — Find My updates the location in real time. You will see the new location appear on the map within seconds.
Play a sound, lock, or erase your iPhone remotely
Find My gives you three options once you locate your device. After tapping your iPhone's name in the Devices list, you will see three buttons: Play Sound, Mark as Lost, and Erase iPhone.
Play Sound makes your iPhone emit a loud alert for two minutes, even if it is in silent mode. Use this if you think your phone is nearby but hidden — under a couch cushion, in a bag, or in another room.
Mark as Lost locks your iPhone remotely and displays a custom message on the lock screen with a phone number where you can be reached. This is useful if someone else has your phone and you want to contact them or make it clear the device is not for sale.
Erase iPhone deletes all data on your device permanently. Use this only as a last resort if you believe your iPhone is stolen and you cannot recover it. Once erased, you cannot use Find My to locate it anymore.
Troubleshoot if your iPhone does not appear in the list
If you sign in with your Apple ID on another device and your iPhone does not show up in the Devices list, the most common reason is that Find My is turned off on your missing iPhone. Check your iPhone's settings before it went missing: open Settings, tap Privacy, then Location Services, and make sure the toggle is on. If you cannot do this because your phone is already lost, you cannot turn it on remotely.
Another reason your iPhone might not appear is if it is signed in to a different Apple ID than the one you are using to search. This happens if you recently changed your Apple ID or if someone else set up the device. In that case, you will need to sign in with the correct Apple ID on the other person's device.
If your iPhone has never been set up with Find My, or if it is too old to support the feature, it will not appear in the list. Find My requires iOS 13 or later. If your iPhone is running an older version, you cannot locate it through Find My.
Use iCloud.com if you do not have access to another iPhone
If the person lending you their device is not available, you can search for your iPhone using any computer with internet access. Go to iCloud.com in a web browser, sign in with your Apple ID, and click Find My iPhone. The map shows your device location the same way it does on the Find My app.
From iCloud.com, you can also play a sound, lock your device, or erase it — the same three options available in the Find My app. This is useful if you are at home or at work and need to search for your iPhone without borrowing someone else's phone.
Frequently Asked Questions
Can I find my iPhone if I never turned on Find My before it went missing?
No. Find My must be enabled on your iPhone before it is lost in order to locate it. If you never turned on Find My in Settings, you cannot use it to search. However, if you set up Family Sharing with family members, they may be able to see your location through that feature instead.
Will the other person know I am signing in with my Apple ID on their phone?
Yes, they will see your name appear in Settings under their account. Always ask permission before signing in with your Apple ID on someone else's device. Sign out immediately after you find your iPhone to remove your account from their phone.
What if my iPhone is in another country?
Find My works the same way regardless of location. The map will show your iPhone's position anywhere in the world, as long as it has an internet connection. The location updates in real time as your device moves.
Can I find my iPhone if it is in airplane mode?
Find My will show the last known location before airplane mode was turned on, but it cannot update the location while airplane mode is active. Once airplane mode is turned off, the location updates within seconds.
What happens if someone else finds my iPhone and turns it off?
Find My continues to show the last location your iPhone reported. If the person who found it turns it back on and it reconnects to the internet, the location updates immediately. You can also use Mark as Lost to display a message asking them to contact you.
