Adding a phone to Find My iPhone means registering a second device so you can track your primary iPhone from it

Find My iPhone works through iCloud, Apple's cloud service. When you sign into iCloud on a second device — whether that's an iPad, Mac, or another iPhone — that device automatically gains the ability to locate your primary iPhone on a map. You do not need to read a separate app or change any settings on your primary phone. The second device straightforward needs to be signed into the same Apple ID account as your primary iPhone.

This is different from adding a family member's phone to Find My. If you want your spouse or child to see your iPhone's location, that requires Family Sharing and a separate step. This section covers adding your own devices only.

Key Takeaways

  • Any device signed into your Apple ID automatically appears in Find My and can locate your other devices.
  • Open Find My on your second device, tap the Devices tab, and you will see your primary iPhone listed if both devices are on the same Wi-Fi or cellular network.
  • If your primary iPhone does not appear in the Devices list, sign out of iCloud on the second device and sign back in with the same Apple ID.
  • Find My requires location services to be turned on for the primary iPhone; if it is off, the second device will show the iPhone's last known location only.

What you need before you start

You need the same Apple ID on both devices. If your second device is brand new or was reset, you will be asked to sign in during setup. If it is already in use, go to Settings, tap your name at the top, and check which Apple ID is signed in. If it is the wrong account, sign out and sign in with the correct one.

Both devices need to be connected to the internet — either Wi-Fi or cellular data. Find My works over the internet, not Bluetooth, so a device in airplane mode will not appear in the list. Your primary iPhone also needs location services turned on. If location services are off, Find My will show only the last place your iPhone was seen before it went offline.

How to see your iPhone in Find My on a second device

Open the Find My app on your second device. If you do not see it on your home screen, swipe down and search for "Find My" in the search box. Tap the Devices tab at the bottom of the screen. You should see a list of all devices signed into your Apple ID, including your primary iPhone.

Tap your iPhone's name. A map will open showing its current location (if location services are on) or its last known location (if location services are off). You will also see options to play a sound on the iPhone, mark it as lost, or erase it remotely. If your iPhone does not appear in the Devices list at all, move to the next section.

What to do if your iPhone does not appear in the list

The most common reason an iPhone does not show up is that the second device is signed into a different Apple ID. Go to Settings on the second device, tap your name at the top, scroll down, and tap Sign Out. You will be asked whether to keep or delete data from that account — choose Keep. Then tap Sign In, enter the same Apple ID you use on your primary iPhone, and wait for iCloud to sync.

If the iPhone still does not appear after signing in with the correct account, restart both devices. Turn off the second device completely, wait 10 seconds, and turn it back on. Then restart your primary iPhone the same way. After both devices restart, open Find My again and check the Devices tab.

If your iPhone appears but shows "No location available," location services are turned off on that device. Go to Settings on your primary iPhone, tap Privacy, tap Location Services, and make sure the toggle at the top is green. You can then go back to Find My on your second device and see the current location.

Adding a family member's phone instead

If you want your spouse, parent, or child to see your iPhone's location, that is a different process called Family Sharing. You both need to be part of the same Family Sharing group. The person whose phone you want to track does not need to do anything — once Family Sharing is set up, their location appears automatically in the Find My app on your device under the People tab, not the Devices tab.

To set up Family Sharing, go to Settings on your iPhone, tap your name, tap Family Sharing, and follow the prompts to invite the other person. They will receive an invitation and can accept it from their own device. Once accepted, you can see their location in Find My under the People tab, and they can see yours.

Why Find My sometimes shows an old location

Find My updates a device's location only when that device is awake and connected to the internet. If your iPhone is in sleep mode or has been off for hours, the map will show where it was the last time it checked in. This is normal and not a sign of a problem.

If you are trying to locate a lost or stolen iPhone, the location shown may be several minutes old. Turning on Lost Mode through Find My will lock the device and display a custom message on the lock screen, which can help if someone finds it. If you believe the iPhone has been stolen, you can also erase it remotely, though this will make it impossible to locate afterward.

Frequently Asked Questions

Can I see my iPhone's location if I do not have another Apple device?

Yes. Go to iCloud.com on any computer or web browser, sign in with your Apple ID, and click Find My. You will see the same map and options as you would in the Find My app. This works on Windows computers, Chromebooks, and any device with a web browser.

Will my iPhone show up in Find My if it is turned off?

No. Once an iPhone is powered off, it stops communicating with Apple's servers. Find My will show only the last location it reported before shutting down. If you turn it back on later, the location will update once it reconnects to the internet.

Does the person whose iPhone I am tracking get notified?

Not if it is your own device on your own Apple ID. If you are tracking someone else's iPhone through Family Sharing, they can see in their own Find My app that you are viewing their location, but they do not receive a notification each time you check.

What happens if I sign out of iCloud on my second device?

You will lose the ability to see your other devices in Find My. You will also lose access to iCloud email, photos, and other synced data on that device. If you sign back in with the same Apple ID later, Find My will work again when ready.
