What the alert says, and the other versions you may see
The alert appears as a notification on your iPhone or iPad. For an AirTag it reads AirTag Found Moving With You. Many people search for it as AirTag detected near you, which describes it well: an AirTag that has been separated from its owner has been seen near your device as you moved from place to place over time.
Apple uses a few related alerts for other devices. For a set of AirPods, you may see AirPods Detected, AirPods Pro Detected, or AirPods Max Detected. For a Find My network accessory or a compatible tracker from another maker, the alert uses that product’s name in place of AirTag. Alerts for compatible trackers from other brands need iOS 17.5 or later.
There is also Unknown Accessory Detected. Apple shows it when AirPods, a Find My accessory, or a compatible tracker is near you but Find My cannot connect to the device or its server at that moment. Apple says this one does not apply to AirTags.
None of these alerts proves that someone is tracking you on purpose. They tell you that a device away from its owner keeps showing up near you, which is worth checking calmly and carefully.
Why you might be getting the alert
Most alerts have an ordinary explanation, but it is worth ruling those out before you relax.
You may be carrying something that belongs to someone else: borrowed keys, a borrowed bag or jacket, or a set of AirPods. Apple notes that the item might be attached to something you are borrowing. A family member’s AirTag on shared car keys or in a shared car is another common cause. An AirTag traveling with its owner should not set off the alert, so a family tag usually triggers it when its owner is not with you. If the item belongs to someone in your Family Sharing group, Apple lets you tap the notification and turn off alerts for that item for one day or indefinitely.
The harmful case is someone hiding an AirTag in your bag, coat, or car to follow where you go. Signs that point that way include a tag you cannot account for in your belongings, an alert that keeps coming back over several days, or someone knowing where you have been without a good explanation. If that might be your situation, treat it as a safety issue and read the steps below with that in mind.
What to do when the alert appears, step by step
Tap the notification. Find My opens a map of where the item was detected near your device: red dots mark each detection, and dashed lines show the order. It is a record of where your iPhone noticed the item, which can help you work out when it first appeared.
Tap Continue. If Play Sound is available, tap it and listen; you can play it again if you need more time. An AirTag is about the size of a coin, so check pockets, bag linings, the bottom of a bag, and anything that was recently handed to you.
On an iPhone with Ultra Wideband, you can tap Find Nearby for an AirTag and follow the directions on screen. Once your iPhone connects, it shows the distance and direction to the tag, and you can turn on the flashlight if you need more light.
When you have the tag in hand, hold the top of your iPhone near its white side. A webpage opens with the serial number and the last four digits of the owner’s phone number; take a screenshot. For other items, open Find My, tap Items, scroll to the bottom, and tap Identify Found Item.
It says an AirTag is following me, but I cannot find it
This is one of the most common and stressful situations, and there are a few reasons it happens.
The speaker may have been removed or muffled, so Play Sound produces nothing you can hear. The tag may be hidden somewhere that blocks sound, such as inside a car seat, under a floor mat, or in a wheel well. Or Play Sound may not be available at all, which Apple says can mean the item is no longer with you or is within range of its owner.
When sound does not help, follow the Bluetooth signal instead. Scan for nearby Bluetooth trackers with TraceIt, pick a signal you do not recognize, and move slowly while the warm and cold finder responds. Compare the reading from several spots and search where it stays strongest. A car is the hardest place to search because metal bodywork distorts signals, so the guide to checking your car for a tracker covers the usual hiding spots and the setup that gives a cleaner reading.
Keep your expectations honest: an AirTag near its owner may expose nothing useful to another app, and iOS hides some Apple-specific data, so a scan can come up empty even when a tag is there. If you still cannot find it and feel unsafe, go to a safe public place and contact the police.
Why the notification went away
An alert can disappear or stop coming back, and that does not always mean the problem is gone.
Apple notes that if an item was with you overnight, its identifier may have changed, which can stop your iPhone from linking it to the earlier detections. Play Sound can also stop working when the item is no longer with you or is back within range of its owner.
To look again, open Find My, tap Items, scroll to the bottom, and tap Unknown Items Detected with You. Also make sure the alerts are still on: go to Settings > Notifications > Tracking Notifications and check that Allow Notifications is turned on. Keep Bluetooth on and Airplane Mode off, since the alerts depend on them.
If the alert went away but you still have reason to worry, search your belongings and your car anyway. The lack of a new alert is not proof that nothing is there.
Document it before you disable it
If you find an AirTag that is not yours, slow down before you take it apart. Photograph the tag, the place you found it, and the owner details from the NFC page. The serial number matters if you involve the police later.
To disable it, tap Instructions to Disable in the alert and follow the steps; for an AirTag, that means removing the battery. Once it is disabled, the owner stops receiving its location and you stop getting alerts for it. Apple also points out that turning off Bluetooth, Location Services, or the Find My network on your own phone does not stop the owner from seeing where the item is. Only disabling the item does that.
Disabling is not always the safest first move. If you think a current or former partner placed it, removing it can tell them you found it, so consider making a safety plan with an advocate first. Our guide on what to do once you find the AirTag covers removing the battery and looking up the owner in more detail.
When to involve the police
Using a tracker to follow a person without their consent is a crime in many countries and regions. If you believe that is happening to you, contact local law enforcement. Bring the AirTag if you have it, its serial number, your screenshots, and notes on where and when you found it. Apple says law enforcement can work with Apple to request information about the item.
If you cannot find the item but feel unsafe, Apple’s advice is to go to a safe public place and contact the police. In the US, the National Domestic Violence Hotline can connect you with an advocate, and Apple’s support page lists other organizations in the US, the UK, and Australia that help with tracking and safety planning.
Getting an AirTag alert on Android
AirTags can follow Android users too. Android 6 and later shows unknown tracker alerts in the background when a tracker that is not yours seems to be moving with you. Tapping the alert shows a map of where it was detected and offers Play sound.
You can also check on demand: go to Settings > Safety & Emergency > Unknown tracker alerts > Scan now. The scan takes about 10 seconds and covers AirTags and Find Hub compatible tags. TraceIt is an iPhone and iPad app, so on Android, Google’s built-in alerts and manual scan are the tools to use.
What TraceIt can add, and what it cannot
Apple’s alert is the first and most important tool, because it uses Find My information that no third-party app can see. TraceIt adds an on-demand view of the Bluetooth signals iOS exposes right now. It labels broadcasts that match known patterns for AirTag-style devices, Samsung SmartTag, Tile, and Chipolo as potential matches, and its warm and cold finder helps narrow down which part of a room, bag, or car a selected signal is coming from. That helps most when Play Sound is unavailable or you cannot hear the tag.
It cannot confirm that a signal is the AirTag from your alert, identify its owner, or decide that a device is following you. An owner-present AirTag may expose nothing useful, and iOS hides Apple-specific advertising data, so detection is not guaranteed. Some trackers from other brands do not set off an iPhone alert at all; to check for those, see how to search for a hidden tracker .
TraceIt is free to download, and TraceIt Pro unlocks the full finder.
