Adding a device to Find My iPhone

To add a phone to Find My iPhone, you sign in with your Apple ID on that device, then turn on Find My iPhone in Settings. The phone automatically appears in the Find My app on any of your other devices where you're signed in with the same Apple ID. You don't need to do anything else — once location services are on (which you learned about in the previous guide), the new device starts reporting its location right away.

The process takes about two minutes and works the same way whether you're adding an iPhone, iPad, or Mac. The key requirement is that every device must use the same Apple ID and have Find My iPhone turned on in Settings.

Key Takeaways

  • Every device you want to track must be signed in with the same Apple ID that you use on your primary phone.
  • You turn on Find My iPhone in Settings on the device itself, not in the Find My app.
  • Once enabled, the device appears automatically in the Find My app on your other devices within a few seconds.
  • Location services must be turned on for Find My iPhone to work, but you can keep other location features off if you want.

Sign in with your Apple ID on the new device

Before you can add a phone to Find My iPhone, it needs to be signed in with your Apple ID. If you're setting up a brand-new phone, you'll enter your Apple ID during the initial setup process. If the phone is already set up, go to Settings, tap your name at the top, and check that you're signed in. If you're not, tap "Sign in to your iPhone" and enter your credentials.

The Apple ID must be the same one you use on the device where you plan to look up locations. If you have multiple Apple IDs, use the primary one — the one you use for iCloud and the App Store on your main phone.

Turn on Find My iPhone in Settings

Open Settings on the phone you want to add. Tap your name at the top, then tap "iCloud." Scroll down and look for "Find My iPhone" — it's usually near the bottom of the iCloud settings list. Tap it, then toggle the switch to turn it on. The switch will turn green.

If you see a prompt asking to use your location, tap "Allow" or "Allow While Using the App." This is separate from the location services toggle you turned on earlier — Find My iPhone needs this permission to report the phone's position to your other devices.

Check that the device appears in Find My

Open the Find My app on any of your other devices signed in with the same Apple ID. Tap the "Devices" tab at the bottom. Within a few seconds, the new phone should appear in the list with a green dot next to its name, meaning it's currently online and sharing its location.

If the device doesn't appear after 30 seconds, go back to Settings on the new phone and make sure the toggle for Find My iPhone is actually on — sometimes it looks on but hasn't saved. Also check that location services are turned on in Settings > Privacy & Security > Location Services.

What to do if a device won't show up

The most common reason a device doesn't appear is that location services are off. Go to Settings > Privacy & Security > Location Services and make sure the toggle at the top is on. Then go back to Settings > [Your Name] > iCloud > Find My iPhone and toggle it off and back on again.

If the device still doesn't show up, sign out of iCloud on that phone and sign back in. Go to Settings > [Your Name], scroll to the bottom, and tap "Sign Out." Enter your Apple ID password, choose what to do with your iCloud data (usually "Keep on My iPhone"), then sign back in. This usually takes a few minutes to sync.

If you're trying to add a device that's offline or has no cellular or Wi-Fi connection, it won't appear until it connects to the internet. Once it does, it should show up within a minute.

Adding multiple devices at once

If you have several phones or tablets you want to track, add them one at a time using the same steps. Each device needs to be signed in with your Apple ID and have Find My iPhone turned on in its own Settings. There's no limit to how many devices you can add — you can track as many as you want from the Find My app.

Once all devices are added, you can see them all in the Devices tab of Find My. You can also set up notifications so that you get an alert when a specific device arrives at or leaves a location, which is useful if you're tracking a family member's phone or a shared iPad.

Frequently Asked Questions

Do I need to add my own phone to Find My iPhone?

No. Your primary phone is automatically set up to use Find My iPhone during initial setup if you sign in with your Apple ID. You only need to manually add other devices like a second phone, iPad, or Mac.

Can I track a phone that belongs to someone else?

Only if they're signed in with an Apple ID that you also have access to, or if they've added their device to a Family Sharing group that you manage. You cannot track a phone without the owner's knowledge or consent — Find My requires the device to be signed in with your Apple ID or to be part of your family group.

What happens if I turn off Find My iPhone?

The device will no longer appear in the Find My app on your other devices, and you won't be able to locate it, play a sound on it, or remotely lock it. You can turn it back on anytime by going to Settings > [Your Name] > iCloud > Find My iPhone.

Does Find My iPhone drain the battery?

Find My iPhone uses very little battery on its own. The bigger battery drain comes from location services being on constantly. If battery life is a concern, you can turn off location services for other apps while keeping it on for Find My iPhone specifically.

Can I add a phone that's not an iPhone?

Find My iPhone only works with Apple devices — iPhones, iPads, Macs, Apple Watches, and AirPods. Android phones cannot be added to Find My iPhone. However, you can use Google's Find My Mobile service for Android devices.
