How item finders work
AirTag, Tile, and Samsung’s SmartTag are small Bluetooth Low Energy (BLE) beacons meant to help you find your own things. Each pairs with an owner’s phone, then leans on a crowdsourced network of other people’s phones to report its location once out of direct Bluetooth range. AirTag uses Apple’s Find My network; SmartTag uses Samsung’s SmartThings Find network; Tile uses its own app-based network (Google Security Blog, Samsung SmartThings Find). Nearby devices detect the tag’s signal and relay its location back to the owner — anonymously, without the finder knowing they helped.
That design also makes these tags misusable for tracking a person instead of a bag. A tag slipped into a coat pocket or backpack reports its location the same way a lost tag would — silently, wherever the owner’s network reaches.
Not every brand alerts you the same way
Apple and Google built a shared way to warn a phone when someone else’s AirTag seems to be following it: a 2024 joint specification, Detecting Unwanted Location Trackers, now being formalized through an IETF working group of the same name (Google Security Blog; IETF DULT working group). Google’s announcement names the manufacturers committed to compatible tags — Chipolo, eufy, Jio, Motorola, and Pebblebee — alongside Apple’s AirTag (Google Security Blog).
Tile is not on that list, and Tile tags do not trigger the automatic iPhone or Android “tracker traveling with you” alert. Life360, which owns Tile, offers a manual Scan and Secure feature instead: anyone with the Tile app — no account needed — can scan for Tiles nearby, but there’s no passive background alert like AirTag’s (Life360 Support). Worse, Tile’s own Anti-Theft Mode makes a Tile invisible to that same scan (Life360 Support). If you suspect an Anti-Theft Mode Tile is on you, contact Life360 support; law enforcement can request the registered owner’s information with a court order.
Samsung SmartTags are also different: SmartThings Find can alert you to unknown SmartTags once you turn that feature on, but Samsung’s documentation only describes what its own app detects — not whether a plain Android phone or an iPhone without SmartThings gets any alert about a SmartTag (Samsung Support).
If you suspect you’re being tracked right now, read Safety first: before you remove anything first.
Make sure alerts are turned on
On iPhone: Settings → Privacy & Security → Location Services (on); Bluetooth (on); Settings → Notifications → Tracking Notifications → Allow Notifications (on); Airplane Mode off (Apple Support).
On Android: Settings → Safety & Emergency → Unknown tracker alerts → Allow alerts (Android 11 and earlier: Settings → Google → Personal & device safety → Unknown tracker alerts). Location generally needs to be on for automatic alerts; manual scanning works without it on Android 11 and up (Google Android Help).
The limits, honestly
Even for brands that alert automatically, it’s a safety feature, not a guarantee.
- It takes time. The system must observe a tag moving with you across multiple locations before alerting, to avoid false alarms from a borrowed bag or shared ride (Google Android Help).
- Turning off Bluetooth or Location doesn’t stop the tracker. It only stops your phone from generating alerts — the tag keeps reporting to its owner through other people’s devices regardless (Google Android Help, Apple Support).
- A tag’s identifier rotates, which can make your phone momentarily treat an already-alerted tag as “new” again (Google Android Help).
- A quiet phone means nothing detected, not nothing present — especially for brands like Tile that need a manual check. See What a scan can and can’t tell you for the broader limits of any privacy scan.
How to run a manual scan
Do this regardless of whether you’ve had an automatic alert — it’s the only way to check for Tile.
iPhone: Find My → Items, tap “Identify Found Item,” or check “Unknown Items Detected with You” for anything already flagged (Apple Support). Android users without built-in detection can install Apple’s Tracker Detect app from the Google Play Store (NY Attorney General).
Android: Settings → Safety & Emergency → Unknown tracker alerts → Scan now — about 10 seconds, finds trackers nearby including AirTags (Google Android Help).
Samsung: SmartThings → Life → Find → three-dot menu → Settings → Unknown tag detection → “Search for unknown tags near you” (Samsung Support).
Tile: Open the Tile app (no account needed) and run Scan and Secure — remembering it won’t find a Tile in Anti-Theft Mode (Life360 Support).
Bags and pockets, under cars, inside bumpers, and behind license plates are the hiding spots New York’s Attorney General points to. A tag separated from its owner for some time also emits a beeping sound on its own (NY Attorney General).
What to do if you find one
New York’s Attorney General has called nonconsensual tracking of a person “a serious felony” — laws vary by state, but this is treated as serious wherever it’s prosecuted (NY Attorney General). A tag you find may be evidence, and how you handle it matters.
Before you touch anything, revisit Safety first: before you remove anything. Once you disable a tag, its owner can no longer see its location or get updates — if you still live with them, that change may be noticed, which can be more dangerous than leaving it running for now (Apple Support).
If you decide to proceed:
- Document it before you disable it. Photograph where you found it. On iPhone, hold your phone near the tag’s white side (NFC on Android) for its serial number and — if reported lost — limited owner contact info (Apple Support). Screenshot everything.
- Don’t contact the owner directly. If you’re concerned for your safety, go to a public place and contact law enforcement instead (Apple Support).
- Decide whether to disable it now or later. Disabling stops future location updates for the owner; leaving it active lets you hand it to police intact. Law enforcement can request account information tied to a serial number, including from Life360 for a Tile in Anti-Theft Mode under a court order (Apple Support; Life360 Support).
- Bring what you have to police. The tag, its serial number, and your screenshots all help. See Documenting it and getting help for a fuller walkthrough.
Not every unknown tag is malicious — plenty turn up because you borrowed a bag, a friend’s AirTag rode along with shared luggage, or someone lost the item near you (NY Attorney General). The alert and scan tools give you the facts to tell the difference — not which one you’re looking at.
