Can an AirTag track your car?

Yes, in the sense that matters: an AirTag in your car records where the car has been, one relayed sighting at a time, and AirTag History keeps those sightings as a route. It is not a GPS tracker. There is no live feed, and a car parked where no iPhones pass simply stops reporting until one does.

What an AirTag in a car actually records

Every point comes from somebody else's iPhone. The tag whispers a Bluetooth identifier, a passing phone hears it, and that phone relays an encrypted report of its own location. The AirTag never knows where it is; it only knows how to be overheard.

For a car this works out better than it sounds. Cars live on roads, roads have traffic, and traffic is full of iPhones. A commute through a town usually produces a dense, believable line. A week in a rural barn produces almost nothing.

Find My will show you the newest of those reports as one pin and throw the rest away. AirTag History polls every 5 minutes and keeps each report with its latitude, longitude, and timestamp, which is what turns a pin into a route.

Where do you hide an AirTag in a car?

Two competing pressures: metal and bodywork absorb Bluetooth, so buried deep is quiet, but anywhere obvious is the first place somebody looks. Aim for concealed but not encased.

• Under a seat, taped up inside the foam or the seat base trim.
• Inside the boot floor, under the spare wheel or the tool tray.
• In the void behind a door card or a rear quarter trim panel.
• Slipped into the headliner above a rear pillar.
• Inside a glovebox or centre console, if you only care about everyday history rather than theft.

• Avoid the engine bay, because heat is hard on a coin cell and the surrounding metal is hard on the signal.
• Avoid anywhere that gets soaked: wheel arches, under the sills.
• Avoid the number plate surround and the tow hitch. Everyone checks the outside of a car first.

One practical note: a coin cell lasts roughly a year, and the day it dies the history stops without any announcement. If the tag is somewhere you need a trim tool to reach, put a reminder in your calendar rather than trusting yourself to notice.

What the history looks like for a car you use every day

Mostly it looks like a smear of points around your house and your workplace, a thin line along the roads between them, and a cluster wherever you parked long enough for someone to walk past.

• Motorway and main-road driving reports well, because there is always another car alongside you.
• A supermarket car park usually fills in within minutes.
• An underground or multi-storey car park often goes silent, then produces one point as you drive out.
• A private driveway in a quiet street can sit for hours between reports even though the car has not moved.

Gaps are shown as gaps. Nothing is interpolated, and no straight line is drawn through a stretch where no phone was listening. A route you can trust is one that admits where it stops knowing.

What happens if the car is stolen?

This is where the honest answer costs us something. If the car is driven into a city, parked on a street and left, you will probably get a usable trail. If it is driven forty minutes out to a yard behind a hedge, the trail can end at the last village it passed through and stay ended for days.

• A metal container, a sealed lorry, or an underground unit will usually stop reports entirely.
• A thief carrying a recent iPhone or Android phone may get an unknown-tracker alert about a tag travelling with them.
• An AirTag that has been away from its owner for a while can start playing a sound when it is moved: a deliberate anti-stalking feature, not a bug.
• The last recorded point is still worth something even when the trail dies: it gives police a direction and a time.

Do not drive to the pin. Give the timeline to the police and let them decide what to do with it. A stranger who has just stolen a car is not a person to go and reason with in a car park.

AirTag or a hardwired GPS tracker?

If you need to know where a vehicle is at every moment, buy the wired tracker; that is what it is for. An AirTag is the cheap option that answers a different question, namely where this car has been, and answers it well enough in populated places.

Whose car are you allowed to put one in?

Your own. A tag in a vehicle you own, driven by you, is tracking a thing. A tag in someone else's car is tracking a person, and that is prohibited by our acceptable-use policy regardless of what the law where you live happens to say about it.

The awkward middle cases, such as a partner's car, a shared family car or an employee's van, turn on consent and on local law, and the rules vary by jurisdiction. We are not the right source for that answer. We support the unknown-tracker alerts built into iOS and Android, and we would rather lose the customer.
