Safety is your top priority

If you’ve found an unknown tracker using our instructions, your first task is to identify it. Don’t destroy it unless there’s no alternative – you may need it as evidence later.

iOS and Android, at least, should prompt you to bring your phone near the tracker and/or otherwise trigger its identification info. This will pop up a serial/device ID, as well as a partially obscured version of the owner’s email address – take a screenshot of this. If retrieving info directly is impossible, you may need to identify the company that made the tracker, and look up specific instructions online. Some trackers will also have serial numbers printed on them.

Be prepared to supply as much evidence as possible.

Assuming the tracker is genuinely suspicious, the next step is to disable itby removing the battery. If you can identify the tracker’s make and model, web instructions should be easy to find. This does risk factory resetting a tracker so that it can’t be directly linked to its owner, but that’s preferable to risking robbery, harassment, injury, or death.

The last major step is to contact local police. Be prepared to supply as much evidence as possible, including photos of the tracker and/or where it was found. Remember, you’re helping to launch an investigation, and possibly even a criminal trial down the road. Even if your actions don’t produce any results, you’ll at least be establishing awareness and credibility.
