What Find My iPhone Does and How to Turn It On
Find My iPhone is Apple's built-in tool that shows you where your iPhone is on a map, lets you play a sound to help you find it nearby, or remotely lock and erase it if it's lost or stolen. The feature works through your Apple ID and iCloud account, and it's turned on in the Settings app under your name.
To turn it on, open Settings, tap your name at the top, select iCloud, then scroll down and toggle Find My iPhone to the on position. You'll need to enter your Apple ID password to confirm. Once it's on, your iPhone's location is sent to Apple's servers and linked to your account — this is what lets you find it from another device or from a computer.
Find My iPhone only works if your phone has an internet connection (either Wi-Fi or cellular data) and location services are already turned on. If your phone is powered off, in airplane mode, or has no signal, the last known location will show instead, but you won't be able to use the sound or lock features until it connects again.
Key Takeaways
- Find My iPhone is turned on in Settings under your name, then iCloud, and requires your Apple ID password to enable.
- You can locate your phone from another Apple device using the Find My app, or from any computer by visiting iCloud.com.
- The three main actions are playing a sound to find a nearby phone, locking it remotely to prevent access, or erasing it completely if it's stolen.
- Your phone must have internet access and location services on for Find My iPhone to work; without them, only the last known location appears.
Finding Your iPhone from Another Apple Device
If you have an iPad, Mac, or another iPhone, the fastest way to locate your missing phone is through the Find My app. Open Find My, tap the Devices tab at the bottom, and select your iPhone from the list. A map will show its current location, and a green dot means it's online and sending its location right now.
If the dot is gray, your phone is offline but the map shows where it last connected. Tap the phone's name to see more details — the address, the time it was last seen, and whether the battery is low. From this screen you can also tap Play Sound to send an alert to your phone (useful if it's nearby but hidden under a couch or in a bag), Lock to remotely set a passcode, or Erase to wipe all data if you believe it's been stolen.
The Find My app works on iOS 13 and later, and on Mac with macOS 10.15 or newer. If you have an older device, you can still use iCloud.com instead to find your phone from any computer.
Locating Your iPhone from a Web Browser
You don't need another Apple device to find your iPhone. Go to iCloud.com from any computer or phone, sign in with your Apple ID, and click Find My iPhone (or Find My on newer versions). A map will load showing all your devices linked to that Apple ID.
Click your iPhone's name to see its location, and the same three options appear: play a sound, lock the device, or erase it. This method works from any computer — Windows, Mac, or Linux — and from any web browser. You only need internet access and your Apple ID password.
If you're using a shared computer, sign out of iCloud when you're done. Your location data stays private — only you and anyone you've shared your location with in the Sharing settings can see where your devices are.
Playing a Sound to Find a Nearby iPhone
If you think your iPhone is close by — in your home, car, or office — the Play Sound option sends a loud alert to your phone for two minutes. This works even if your phone is on silent mode, and the sound is loud enough to hear from another room.
From Find My on another device or from iCloud.com, select your iPhone and tap Play Sound. Your phone will emit a distinctive tone. If you hear it, follow the sound to locate your phone. The sound stops after two minutes, but you can tap Play Sound again if you need to.
This feature only works if your phone has power and an internet connection. If the battery is dead or the phone is offline, the sound won't play, but you'll see the last location where it was connected.
Locking Your iPhone Remotely
If you can't find your phone and believe it may be lost or stolen, you can lock it remotely to prevent someone else from accessing your data. From Find My or iCloud.com, select your iPhone and tap Lock (or Lost Mode on some versions).
You'll be asked to set a new passcode — this can be different from your regular unlock code. Once you confirm, your phone will lock when ready, and anyone trying to use it will see the passcode screen. You can also add a phone number and message that appears on the lock screen, like "If found, please call [your number]."
A locked phone can still be tracked on the map, and the person holding it can still make emergency calls. If you later find your phone, you can unlock it with the passcode you just set, or you can erase it instead if you prefer.
Erasing Your iPhone Remotely
If your phone is stolen and you're certain you won't recover it, you can erase all data on it remotely. From Find My or iCloud.com, select your iPhone and tap Erase. You'll be asked to confirm — this action cannot be undone, and all photos, messages, contacts, and apps will be permanently deleted.
After erasing, your phone will restart and show the setup screen, as if it just came from the factory. The person who has it cannot access any of your personal information. However, once erased, you won't be able to track the phone's location anymore, so only do this if you're certain it's gone.
If you erased your phone by mistake, you can still track it using the last known location, but you cannot restore the data remotely. You would need to recover it from a backup on your computer or iCloud if you have one.
What to Do If Find My iPhone Isn't Working
If you can't locate your phone, check these things first. Make sure Find My iPhone is actually turned on in Settings — go to your name, iCloud, and verify the toggle is on. Check that location services are on in Settings under Privacy, and that your phone has either Wi-Fi or cellular data connected.
If your phone is offline or powered off, Find My will show only the last location where it connected, which may be hours or days old. If you're trying to find a family member's phone, make sure they've shared their location with you in the Sharing settings — you can't see someone else's location without their permission.
If Find My still doesn't work, sign out of iCloud on your phone and sign back in. Go to Settings, tap your name, scroll to the bottom, tap Sign Out, then sign back in with your Apple ID. This refreshes your connection to Apple's servers and often fixes location problems.
Frequently Asked Questions
Can I find my iPhone if it's turned off?
No, but Find My will show the last location where your phone was on and connected to the internet. If your phone has been off for hours, that location may not be current. Some newer iPhones have a feature called Find My when offline that can still transmit location even when powered down, but this requires the phone to have been set up with this feature before it was turned off.
Does the person with my phone know I'm tracking it?
No. Find My iPhone sends location silently to Apple's servers and does not notify the person holding the phone. However, if you lock the phone or play a sound, they will know something is happening. If you erase the phone, they will see the setup screen appear.
What if I share my location with family members?
Family members you've shared location with in the Sharing settings can see your iPhone on their Find My app. You can stop sharing anytime by going to Settings, your name, Family Sharing, and toggling off location sharing. They won't be notified when you turn it off.
Can I find my iPhone if I don't remember my Apple ID password?
You'll need your Apple ID password to access Find My iPhone from iCloud.com or another device. If you've forgotten it, go to iforgot.apple.com and follow the steps to reset it. Once you've reset your password, you can sign into iCloud.com and locate your phone.
Will Find My iPhone work if my phone is on airplane mode?
No. Airplane mode turns off all wireless connections, including Wi-Fi and cellular data, so your phone cannot send its location. Find My will show the last known location from before airplane mode was turned on.
