How to find an unknown tracker following you
Most recent phones alert you when an unknown tracking tag seems to be moving with you, and many can scan for one manually from the safety or tracker settings. If you get an alert, use the phone to play a sound on the tag and find it in your bag, car or clothes. If you feel unsafe, go somewhere public rather than home and contact a hotline or the police before disabling it.
Why it matters: Small tracking tags are cheap, and phones can now scan for unknown ones.
Steps
- Make sure Bluetooth and your phone's unknown tracker alerts are turned on in settings.
- If an alert appears, open it and choose the option to play a sound.
- Search your bag, coat pockets, car seats, wheel wells and the trunk while the tag chirps.
- Run a manual scan from the tracker settings if you are worried but have no alert.
- Photograph the tag and any serial number or owner information your phone shows.
- If you feel unsafe, go to a public place or a police station, not home.
- Contact a domestic violence hotline or the police before disabling the tag if you think a specific person placed it.
Stop and call a professional if
- you find a tracker you did not place and feel unsafe: go somewhere public and call your local emergency number, 911 in the US, or a domestic violence hotline
Common mistakes
- Taking the tag home, which can show the owner where you live.
- Destroying the tag before recording its details.
- Ignoring repeated alerts because nothing was found the first time.
