What Find My iPhone does and how to start

Find My iPhone is Apple's built-in tool that shows you where your iPhone is on a map, plays a sound to help you locate it nearby, or remotely locks and erases it if it is lost or stolen. You access it through iCloud.com from any web browser, or through the Find My app on another Apple device.

The tool works only if you turned on location services beforehand — which you learned about in the previous guide. If location services are off, Find My iPhone cannot pinpoint your phone's location, though you can still lock it remotely or erase it if you know your Apple ID password.

Before your iPhone goes missing, you need to set up Find My iPhone on the phone itself. This takes about two minutes and requires your Apple ID and password. If you have not done this yet, do it now while you have the phone in hand.

Key Takeaways

  • Find My iPhone must be turned on in Settings before your phone is lost, so set it up now even if you do not think you will need it.
  • You can locate your phone, play a sound on it, lock it, or erase it from iCloud.com using any web browser and your Apple ID.
  • Location services must be on for Find My iPhone to show you a map; without it, you can still lock or erase the phone remotely.
  • If you use Find My app on another Apple device, the steps are slightly different but the options are the same.

Turning on Find My iPhone in Settings

Open Settings on your iPhone and tap your name at the top of the screen. Then tap iCloud. Scroll down until you see Find My iPhone and tap it. Toggle the switch to the right so it turns green. You will be asked to enter your Apple ID password — type it in and tap Allow.

That is all you need to do. Find My iPhone is now on. If you ever sell or give away your iPhone, you will need to turn this off before handing it over, otherwise the new owner cannot use the phone without your Apple ID. To turn it off later, follow the same steps and toggle the switch to the left.

Finding your iPhone from iCloud.com

Go to iCloud.com in any web browser on a computer or another phone. Sign in with your Apple ID and password. Click Find My iPhone (you may need to click Find My first, depending on your Apple ID region).

A map will appear showing all your Apple devices. Click the device you are looking for. A panel will open on the right side with three options: Play Sound, Mark as Lost, and Erase iPhone. If your phone is in the house or nearby, click Play Sound — your iPhone will make a loud noise for two minutes, even if it is on silent.

If the map shows your phone in a location you do not recognize, or if you cannot find it after playing the sound, you have two more choices. Mark as Lost locks the phone with a passcode and displays a message on the screen with your phone number, so if someone finds it they can call you. Erase iPhone wipes all data from the phone permanently — use this only if you are certain you will not find it and you want to protect your personal information.

Using Find My app on another Apple device

If you have an iPad, Mac, or another iPhone, you can use the Find My app instead of going to iCloud.com. Open Find My and tap or click the Devices tab at the bottom. You will see a list of all your Apple devices. Tap or click the iPhone you are looking for.

The same three options appear: Play Sound, Mark as Lost, and Erase. The steps work the same way as they do on iCloud.com. If you do not see the Find My app on your device, it may not be installed — check the App Store to read it.

What to do if Find My iPhone shows no location

If the map shows your phone but no specific address, or if it shows a very old location, location services may be off or your phone may not have a signal. Try playing a sound first — if your phone is nearby and powered on, you will hear it even if the map is not accurate.

If you cannot hear anything and the location has not updated in hours, your phone is likely powered off, out of battery, or in an area with no cell service. In this case, Mark as Lost is your best option. It locks the phone so no one can access your data, and it sends you a notification if the phone comes back online and reconnects to the internet.

Protecting yourself if your iPhone is truly lost

If you have marked your phone as lost and several days pass with no sign of it, you should contact your phone carrier (Verizon, AT&T, T-Mobile, or whoever you use) and ask them to deactivate the phone on their network. This prevents someone from using your phone number to make calls or send messages. You will also want to change your Apple ID password from another device, in case someone tries to access your accounts.

If your phone is stolen rather than lost, file a report with local police and keep the report number. Some carriers and insurance companies require a police report before they will replace a stolen phone. You can also report the theft to Apple by visiting their support website, though this is not required to use Find My iPhone.

Frequently Asked Questions

Can I find my iPhone if it is turned off?

No. An off phone cannot send its location to Apple's servers. However, if the phone turns back on later and reconnects to the internet, you will see its new location. If you marked it as lost, you will receive a notification when it comes back online.

Will the person who finds my phone see my location?

No. Find My iPhone is hidden from the lock screen and home screen. Only you can see the location by signing into iCloud.com or the Find My app with your Apple ID. The person who finds it cannot access this information.

What happens if I erase my iPhone?

All photos, messages, apps, and files are permanently deleted. The phone will restart and show the setup screen as if it were brand new. You cannot undo an erase, so use this option only when you are certain you will not recover the phone.

Can I use Find My iPhone if I forgot my Apple ID password?

No. You must sign into iCloud.com or the Find My app with your Apple ID password. If you forgot it, go to iforgot.apple.com to reset it using your email address or phone number.

Does Find My iPhone work if my phone has no cell service?

It depends. If your phone is connected to Wi-Fi, Find My iPhone can still locate it. If it has no internet connection at all, the map will show the last known location before the connection was lost, which may be hours or days old.
