How to tell if someone is tracking you with an AirTag

How AirTag anti-stalking protection works

AirTags and other Find My accessories are designed to help people find their own belongings. To discourage misuse, a tracker that is separated from its owner and seen moving with you over time triggers a notification on a nearby iPhone or Android phone, or makes the tracker itself play a sound.

These trackers use Bluetooth identifiers that change frequently, which protects their owner’s privacy but also means a phone needs some time to be sure the same tracker is travelling with you. Apple does not publish exactly how long that takes. In 2024, Apple and Google added cross-platform alerts based on a shared industry specification, Detecting Unwanted Location Trackers, so phones can warn about compatible trackers regardless of which platform they belong to.

Sign 1: your iPhone shows “AirTag Found Moving With You”

On an iPhone or iPad, the alert reads “AirTag Found Moving With You”, or “[Product name] Found Moving With You” for other Find My accessories and compatible trackers. Tapping it opens Find My with a map of where the item was detected with you.

• The red dots on the map show where the unknown item was detected near your iPhone — they do not show when its owner looked at it.
• Tap Continue and then Play Sound to make the item beep.
• For an AirTag, iPhones with Ultra Wideband can use Find Nearby (Precision Finding) to show the distance and direction.
• Variants such as “AirPods Detected” mean someone else’s AirPods are moving with you; “Unknown Accessory Detected” appears when Find My cannot connect to the item.

Apple lists these conditions for receiving tracking notifications: iOS or iPadOS 17.5 or later (14.5 for AirTag and Find My items), Location Services on, Significant Locations on, Bluetooth on, Tracking Notifications allowed, and Airplane Mode off.

Sign 2: your Android phone shows an unknown tracker alert

Android 6.0 and later can notify you when someone else’s tracker that is separated from its owner is moving with you. Google says the alerts work with Find Hub network compatible tags, headphones and Apple AirTags.

• Tap the notification to see a map of where the tracker was detected with you, then tap Play sound. Google says playing the sound does not notify the owner.
• For Find Hub compatible trackers, Find nearby guides you as you get closer.
• Run a manual scan at any time: Settings › Safety & emergency › Unknown tracker alerts › Scan now. It takes about 10 seconds.
• Past alerts are listed in the same place; Google notes that they are deleted after 48 hours, so take screenshots.

Sign 3: you hear an unexplained chirp

An AirTag — and other Find My accessories or compatible trackers — that has been separated from its owner for a period of time plays a sound when it is moved. If you hear an unfamiliar chirp from your bag, coat or car, look for a tracker.

Don’t rely on the sound alone. It only starts after a while, it is easy to miss inside a car or a bag, and there have been reports of AirTags modified so that they make no sound. A silent tracker can still be found by alerts and by a Bluetooth scan.

Sign 4: the same unknown device keeps turning up

The clearest sign that a tracker is following you is that the same unknown device appears at different places you go. A dedicated scanner lets you check this yourself instead of waiting for an alert.

In TrackerSonar, each scan lists possible trackers first. SUSPICIOUS marks tags that can be used to track people and that you haven’t marked as your own, and TRACKED marks a device your scans found at places more than 50 m apart (this needs location access). With Premium, the sightings map and “Is it following me?” timeline show when and where the device turned up. Keep in mind that trackers change their Bluetooth address from time to time, so after a change the same tag can appear as a new device.

Step by step: check yourself for a hidden AirTag in about 10 minutes

1. Make sure your phone’s tracker alerts are on. On iPhone: update iOS, then check Location Services, Significant Locations (Settings › Privacy & Security › Location Services › System Services), Bluetooth and Settings › Notifications › Tracking Notifications. On Android: open Settings › Safety & emergency › Unknown tracker alerts and make sure alerts are allowed.
2. Look at alerts you may have missed. On iPhone, open Find My, tap Items and scroll to Unknown Items Detected with You. On Android, open the Unknown tracker alerts screen.
3. Scan for trackers near you now. On Android, tap Scan now. On iPhone, iPad or Android, you can also scan with a tracker detector such as TrackerSonar, which lists AirTags, Tile, SmartTag, Chipolo and other tags around you and flags unknown ones.
4. Check your belongings and car. Bags (including linings and outer pockets), coat pockets, your car’s interior and boot. See how to find a hidden tracker for a full checklist.
5. Scan again somewhere else. Go to a different place — ideally more than a few hundred metres away — and scan again. A tag that turns up in both places is more likely to be travelling with you; one that only appears at home may simply belong to a neighbour.
6. Decide what to do next. If you find a tracker, read what to do if you find a tracker before you disable it.

Innocent explanations to rule out

• You borrowed something with a tracker attached, such as keys, a bag or a car.
• You are travelling with someone who carries an AirTag, for example in their luggage.
• You are using someone else’s AirPods.
• A family member’s tag: if they are in your Family Sharing group, you can turn off alerts for their item for a day or indefinitely.

Ruling these out takes a few minutes and avoids unnecessary worry — but if you can’t explain a tracker, take it seriously.
