Use Find My to locate your AirTag on a map

Open the Find My app on your iPhone, iPad, or Mac. Tap or click the Items tab at the bottom. You will see a list of all your AirTags. Tap the one you are looking for, and the app will show you its location on a map — either the exact spot if it is nearby, or the last known location if it is far away.

If your AirTag is within Bluetooth range (roughly 30 feet in open space, less through walls), the map will update in real time as you move closer. The app will also show you the distance and direction. Walk toward the location while watching the distance number shrink. When you get very close, tap Play Sound to make the AirTag emit a loud beep that helps you pinpoint it in a drawer, under a couch, or inside a bag.

If your AirTag is far away — lost at a store, in a taxi, or at someone else's house — you will see only the last location where it was detected. This location comes from the last time another Apple device passed near it and reported its position back to Apple's servers. The location may be hours or days old depending on foot traffic in that area.

Key Takeaways

  • Find My shows your AirTag's location on a map and lets you play a sound to find it nearby.
  • The Play Sound feature works only within Bluetooth range, roughly 30 feet in open space.
  • If your AirTag is far away, Find My shows the last location where another Apple device detected it, which may be old.
  • You can mark an AirTag as lost to notify you if it is ever detected again, and show a phone number on its screen.
  • AirTags work only with Apple devices — you cannot track them from Android phones or Windows computers.

Mark your AirTag as lost to get alerts when it is found

If you cannot find your AirTag nearby and believe it is truly lost, open Find My, tap the AirTag in the Items list, and scroll down to tap Mark as Lost. This turns on notifications: if any Apple device detects your AirTag in the future, you will receive an alert with its location.

When you mark an AirTag as lost, you can also add a message and phone number that will appear on the AirTag's screen if someone finds it and taps it with their iPhone. This gives a stranger a way to contact you without opening the AirTag itself. The message might say something like "If found, please call 555-0123" or "This AirTag belongs to Sarah. Please contact me."

Mark as Lost does not prevent the AirTag from working normally — it just adds a layer of notification and contact information. You can turn off Mark as Lost at any time by opening Find My, tapping the AirTag, and tapping Mark as Lost again to toggle it off.

Check your AirTag's battery and replace it if needed

An AirTag with a dead battery will not send location updates. Open Find My, tap the AirTag, and look at the battery percentage shown near the top of the screen. If the battery is very low or shows no percentage at all, the battery may be dead.

AirTags use a standard CR2032 coin-cell battery, the same type found in watches and calculators. To replace it, hold the polished stainless steel back of the AirTag and twist it counterclockwise until it pops off. Remove the old battery, drop in a new CR2032 (available at any drugstore or supermarket for a few dollars), and twist the back on again until it clicks. The AirTag will chime to confirm the battery is working.

If your AirTag is still not showing up in Find My after a battery replacement, try removing it from your account and adding it again. Open Find My, tap the AirTag, scroll to the bottom, and tap Remove Item. Then hold a new or existing AirTag near your iPhone to add it back to your account.

Understand the limits of AirTag range and detection

An AirTag uses Bluetooth to communicate with your iPhone or iPad when it is nearby. Beyond that range, it relies on the Find My network — a system where millions of Apple devices report the location of lost AirTags they pass. This means a lost AirTag in a remote area with few Apple devices may never be detected again.

The Play Sound feature works only within Bluetooth range, which is typically 30 feet in open space but much shorter through walls, metal, or dense materials. If your AirTag is in a building across town, you will not be able to make it beep from your phone. You will only see its last known location on the map.

AirTags are designed to work with Apple devices only. If you have an Android phone or Windows computer, you cannot use Find My to track an AirTag. You can view the location only from an iPhone, iPad, or Mac.

Prevent future loss by using AirTag notifications

Find My can alert you if you leave an AirTag behind. Open Find My, tap the AirTag, and scroll down to Notifications. Turn on Notify When Left Behind. From then on, if you leave your AirTag at a location and walk away, your phone will send you a notification after a few minutes.

This feature works best for places you visit regularly, like your home or office. You can add specific locations by tapping Add Location and selecting a place from your contacts or maps. The AirTag will not alert you if you intentionally leave it somewhere — the notification comes only after you have been away for a while.

You can also see a history of everywhere your AirTag has been. Open Find My, tap the AirTag, and scroll to Items to see a timeline of locations. This history helps you retrace your steps if you remember roughly when and where you last had the AirTag.

What to do if someone else's AirTag is following you

If you have an iPhone and notice an unknown AirTag traveling with you, your phone will alert you after a few hours. The notification will say "Unknown AirTag Detected" and offer to show you its location. This safety feature prevents someone from secretly tracking you using an AirTag.

If you see this alert, tap it to see the AirTag's location on a map. You can also tap Play Sound to make it beep so you can find and remove it. If you believe the AirTag is being used to track you without consent, you can tap Disable to turn it off, or remove the battery entirely.

Android users do not receive these automatic alerts. If you use an Android phone and suspect you are being tracked, you can read the Tracker Detect app from Google Play to scan for unknown AirTags nearby.

Frequently Asked Questions

Can I find my AirTag if it is turned off?

No. An AirTag that is powered off or has a dead battery cannot send location data. You will see its last known location in Find My, but it will not update. Replace the battery or wait until the AirTag is turned back on to get a fresh location.

What if my AirTag is in airplane mode or out of range?

An AirTag does not have an airplane mode setting. If it is out of Bluetooth range and no Apple devices have detected it recently, Find My will show only its last known location. The location will not update until another Apple device passes near it.

Can I track my AirTag from a Windows computer?

No. Find My works only on iPhone, iPad, and Mac. If you use Windows, you cannot track an AirTag. You would need to borrow an Apple device or use the Tracker Detect app if you have an Android phone.

How long does an AirTag battery last?

A CR2032 battery in an AirTag typically lasts about one year with normal use. Find My will notify you when the battery is low, usually a few weeks before it dies completely. Replacement batteries cost a few dollars and take less than a minute to install.

Will Find My work if my iPhone is off?

No. Your iPhone must be powered on and connected to the internet for Find My to work. If your phone is off, you cannot see your AirTag's location until you turn it back on.
