Imagine discovering a tiny tracking device hidden in your purse, car or child’s diaper bag. How long has it been there? Who put it there? And how much does that person know about where you’ve been?
Apple AirTags and similar Bluetooth trackers make finding lost belongings easier. Unfortunately, they’re also small enough to conceal almost anywhere, making them attractive tools for stalking, harassment and domestic abuse.
A November 2026 article in Quartz (opens in a new tab) highlighted guidance from the Electronic Frontier Foundation (opens in a new tab) (EFF) on identifying unwanted Bluetooth trackers. The advice is particularly relevant to people who suspect a current or former partner may be monitoring their movements.
Here’s how to check whether you’re being tracked, why your phone might not warn you and what to consider before disabling a suspicious device.
How Can Someone Track You With an AirTag?
An AirTag is roughly the size of a quarter. Despite its tracking capabilities, it doesn’t contain a GPS receiver.
Instead, it uses Bluetooth signals that nearby Apple devices can detect. Those devices help update the AirTag’s approximate location through Apple’s Find My network, allowing the registered owner to locate it.
For someone secretly following another person’s movements, this technology can reveal where that person travels, works or spends time.
How to Check for an Unknown AirTag on Your iPhone
Apple’s unwanted-tracking alerts can notify you when an unfamiliar AirTag or other compatible device appears to be traveling with you.
You might see a notification such as “AirTag Found Moving With You.”
To make sure these alerts are enabled:
- Open Settings → Privacy & Security → Location Services and turn Location Services on.
- Under Location Services, open System Services and enable Significant Locations.
- Return to Settings and make sure Bluetooth is enabled.
- Go to Settings → Notifications → Tracking Notifications and enable Allow Notifications.
- Make sure Airplane Mode is off.
Apple recommends keeping your iPhone updated. Detection of a broader range of compatible Bluetooth trackers requires iOS 17.5 or later.
If you receive an alert, open it and follow the instructions. Apple’s Find My app may show where the device was detected traveling with you and allow you to play a sound to help locate it.
For additional guidance, see Apple’s instructions for responding to unwanted-tracking alerts (opens in a new tab).
Can Android Phones Detect Apple AirTags?
Yes. You don’t need an iPhone to receive warnings about an unfamiliar AirTag.
Google’s built-in unknown-tracker alerts are available on Android 6 and later, although the trackers supported depend on compatibility.
You can also initiate a manual search:
- Open Settings on your Android phone.
- Select Safety & emergency.
- Tap Unknown tracker alerts.
- Select Scan now.
The scan checks for compatible trackers nearby that are separated from their owners.
If your phone detects a suspicious device, you may be able to make it play a sound or view information to help identify it.
Google provides additional instructions in its guide to finding unknown trackers (opens in a new tab).
Why Might Your Phone Fail to Warn You?
One of the biggest limitations of Bluetooth tracking alerts is that no notification doesn’t necessarily mean nobody is tracking your movements.
Phones generally look for signs that an unfamiliar device has been moving with you over time. A tracker may be nearby without triggering an immediate warning.
Other limitations include:
- Tracking notifications may be disabled in your phone’s settings.
- Airplane Mode can interfere with iPhone tracking alerts.
- Some older or incompatible Bluetooth devices may not trigger automatic warnings.
- A tracker that’s still near its registered owner may not meet the conditions for an alert.
- Someone with access to your phone may have changed its security or notification settings.
The last possibility is particularly concerning in abusive relationships.
In a Washington State lawsuit filed against Apple in October 2026, a woman alleged that her husband concealed three AirTags in family belongings and disabled unwanted-tracking notifications on her iPhone without her knowledge.
Other people’s phones reportedly detected the devices, while hers allegedly remained silent.
The case exemplifies why relying entirely on automatic alerts may not be enough.
Where Should You Look for a Hidden Bluetooth Tracker?
The EFF recommends combining electronic detection with a physical search when unwanted tracking is suspected.
Depending on what you’re comfortable checking, possible hiding places include:
- Purses, backpacks, diaper bags and luggage.
- Coat pockets and clothing linings.
- Vehicle compartments, seat pockets and upholstery.
- Items that someone else regularly handles or has given you.
You don’t need to dismantle your vehicle or search every inch of your belongings. If you suspect a tracker is concealed somewhere difficult to reach, a trusted mechanic or other professional may be able to help.
Third-party detection apps, including AirGuard, can provide another way to search for certain Bluetooth devices. However, the EFF cautions that these tools aren’t completely reliable and may also identify harmless trackers belonging to people nearby.
What Should You Do if You Find an AirTag You Don’t Recognize?
Discovering a hidden tracker can be unsettling, particularly if you suspect an abusive partner or someone who has threatened you.
Your immediate safety matters more than disabling the device.
The EFF warns that removing a tracker’s battery or otherwise stopping its location updates may alert the person monitoring it. Depending on the circumstances, that could increase the risk of retaliation.
Consider these steps:
- Move somewhere safe if necessary.
If you feel threatened, contact a trusted person, domestic violence advocate or law enforcement. - Document what you found.
Save screenshots of tracking alerts, maps and any available device information. - Record identifying details.
An AirTag’s serial number and limited owner information may be accessible by holding it near a compatible NFC-enabled phone. - Consider preserving the device.
It could become evidence in a stalking investigation or civil lawsuit. - Develop a safety plan before disabling it.
An advocate can help you evaluate the safest next steps for your circumstances.
If you’re experiencing domestic abuse or stalking, the National Domestic Violence Hotline (opens in a new tab) offers safety-planning guidance. You can call 800-799-SAFE (7233) or text START to 88788.
Can You Take Legal Action Over Secret AirTag Tracking?
Potentially. Using a tracking device to monitor someone without consent may violate stalking, harassment or privacy laws, depending on the circumstances and location.
Some survivors have also filed civil lawsuits against Apple, alleging that the company failed to implement adequate protections against misuse of its AirTags.
These cases address defective product design, notification safeguards and whether Apple did enough to address known stalking risks.
You don’t necessarily have to know who registered a hidden tracker before discussing your legal options with an attorney.
If you discover suspicious tracking, preserving available evidence and documenting what happened may help establish the circumstances of your case.
