How to find and block an AirTag that’s detected near you

The AirTag from Apple is a compact tracking device that offers precise locating ability. Unlike a GPS tracker, which requires cell service and may drain a battery quickly, an AirTag relies on the distributed Find My network of iPhones, iPads, and Macs that hundreds of millions of people around the world carry with them, and uses Bluetooth LE to send a signal to other devices.

While there are a thousand positive and legitimate ways to use an AirTag, it can be abused to let someone track you without your knowledge, potentially exposing you to a dangerous situation. For example, back in December 2021, the York regional police department in Canada announced that AirTags were being placed in hidden areas of target cars parked in public, and then tracked to the driver’s residence, where the cars are stolen while parked in the driveway. In another incident, a woman claimed that she found an AirTag hidden in her wheel well after her iPhone alerted her to an AirTag moving with her. State governments in New York and Pennsylvania have issued warnings about the misuse of AirTags and similar tracking devices.

Incidents like this are rare (at the time, York police said there had been five AirTag-involved thefts out of 2,000 in the region). Apple has put some safeguards in place so that an iPhone, iPad, and AirTag provide varying alerts and information if the owner who paired the AirTag with their iPhone or iPad isn’t nearby. There are tools built into the iPhone to find and disable AirTags as well as an Android app that will scan for AirTags nearby. This is why you may have seen a warning that an AirTag has been detected near you.

These warnings aren’t restricted to Apple devices: in May 2023, Apple and Google announced a joint initiative to allow Bluetooth location-tracking devices to be compatible with unauthorized tracking detection and alerts across iOS and Android platforms.

How an AirTag can track you

Because AirTags don’t register proximity except to the owner, the only way it can be used to gather information about you is if it travels with you. An AirTag in your home, office, or classroom won’t reveal anything to someone trying to keep tabs. That reduces the “surface area” of unwanted surveillance because the AirTag has to be in your clothes, wallet, or purse, something else you’re carrying, or in a vehicle you’re in and using exclusively or at least regularly.

If you’re traveling regularly through urban and suburban areas or on public transportation, other people’s devices will still pick up and relay location information about any AirTag that’s with you. That can include something as innocuous as pulling over to a rest area on a highway, and someone 50 feet away has an iPhone, or even driving on a highway near other people who have iPhones or iPads connected to a cellular network.

Bluetooth LE’s range is surprisingly long. I found that an AirTag I temporarily placed in my car, parked two flights of stairs down from our ground floor and about 50 feet from the house still provided regular updates about its location via devices I owned—not to mention those of neighbors walking or driving by.

Everyone’s devices participate in relaying secured, privacy-protecting location information about their devices and AirTags unless they opt out of the Find My network. That makes everyone around you a potential participant in tracking you via an AirTag you don’t know about.

Once the AirTag is in your possession it will relay its location to the owner via the Find My network and other Bluetooth devices.

How to know you are being tracked by an AirTag

Apple issues alerts to let someone know that there’s an AirTag near them that isn’t associated with their iCloud account. These alerts happen after some period of time or while you’re moving and the AirTag is moving with you.

Should an unknown AirTag be tracking you you will see an alert that will state: “AirTag Found Moving With You”. Apple will invite you to open the Find My app on your iPhone to go through various options to disable the tracking and locate the AirTag, discussed below. (Incidentally, you may also see an alert for other devices moving with you, such as AirPods and other Bluetooth trackers).

Apple recognizes that it could be an innocent case of having borrowed an item from someone with an AirTag attached or inside it, so one of the options is to Pause Tracking Notifications.

To make sure you will receive an alert like this follow these steps:

You will need to have an iPhone or iPad running iOS/iPadOS 14.5 or later.

1. Open the Find My app.
2. Tap the Me tab.
3. Tap Customise Tracking Notifications.
4. Make sure the Allow Notifications slider is green (it should be by default).

Via the alert, you can see how long this AirTag has been with you. You can also see a map of the locations where the AirTag has been tracked in your possession, which may give you an indication of where you picked it up.

How to find an AirTag that’s tracking you

Luckily Apple makes it easy to locate the AirTag that is tracking you. Here’s what to do if you have seen a warning from Apple that an AirTag is following.

One option is to use Apple’s Find My app to manually scan for AirTags near you using the Items That Can Track Me option in the Items tab.

If you have an Android phone, you can also check for unknown AirTags moving with you using the Tracker Detect app. It’s far less robust than Apple’s Find My app and needs to be run manually.

1. Play a sound to locate the AirTag

You may find that the tracking AirTag will play a sound once it has been separated from its owner for a time and then moves.

This happens after what Apple calls an “extended period of time” away from its paired iPhone or iPad (the company has disclosed elsewhere that this is three days). After this period, an AirTag makes a beep whenever it’s moved. If you hear an unexpected beep from something you’re carrying or within your vehicle, then it’s time to engage in the hunt for an AirTag.

The audio alert winds up being less useful than one might hope. If a stalker or other person engaged in surveillance can come within range of the AirTag at least every three days, and they know you don’t have an iPhone or iPad that’s running 14.5 or later, they can reset that counter. The beep that’s made isn’t ongoing or particularly loud, and it can be muffled without blocking the Bluetooth signal substantially.

If you haven’t heard a beep, or want to hear it again, you can force the AirTag to play a sound.

If you have received an alert about an AirTag that is traveling with you and want it to make a sound follow these steps:

1. Tap Apple’s Alert.
2. Tap Continue.
3. Tap Play Sound.

You will have the option to play the sound again.

You may find that there is no option to play a sound, in that case, the item may no longer be near you or it may be back in range of its owner,.

Another reason why you may not be able to find the AirTag is that it may have changed its identifier (which happens regularly). The Bluetooth ID produced by an AirTag, and by all Apple devices that participate in Find My crowdsourcing, changes on a regular basis to avoid becoming a reverse tracking item: if it were persistent, then someone could track your devices based on the “anonymous” Bluetooth ID. That means that your iPhone or iPad has to notice an AirTag moving with it over a relatively short period of time.

Another possibility is that the AirTag speaker has been disabled. After reports of people disabling AirTag speakers, Apple announced that it would add a notification along with the sound on an iPhone, iPad, or iPod touch it is moving with. Apple also says it will adjust the tone sequence that plays when a user has an unknown AirTag traveling with them to make an unknown AirTag easier to find. In a 2022 firmware update version 1.0.301, Apple tweaked the unwanted tracking sound to “more easily locate an unknown AirTag.”

If you own the AirTag it is easy to locate it using the Find My app on an iPhone or iPad to play an audible sound on the AirTag. As part of macOS 13.1, this feature also came to the Find My app on Macs.

2. Use Precision Finding to find the AirTag

As well as the option to play a sound the alert will also give you the option to use Precision Finding if that is available on your device. Your iPhone would need to support Ultra Wideband via the U1 chip to precisely locate an AirTag, which includes iPhone 11 and later.

If Apple’s Alert gives you the option for directions tap Go and you should see directional arrows pointing you in the right direction and a guide to the distance between you and the device. This should help you locate it.

So, for example, if you were trying to find an AirTag in your car you could use Find Nearby and follow onscreen directions to locate the AirTag. It should display distance and direction so you can find the AirTag in your car (although, in this case, it would probably be easier to play the alert sound.)

3. Search for the AirTag

If you didn’t manage to get it to make a sound and Precision Finding wasn’t the answer for you you will need to look for the AirTag.

The first step is to get familiar with what it looks like. If you haven’t seen an AirTag before, consult Apple’s site. They have a rounded white top and a silver base, are somewhat larger than an American quarter or a dollar/pound/single unit coin in many countries, and about three to four times thicker.

As we mentioned earlier, the AirTag has to be moving with you for Apple to have sent the alert, so look inside things that you have with you when you move around:

• Check pockets: In clothing, not just pockets but also check inside the lining or anywhere it could have been sewn in.
• Check bags: Look inside purses, luggage, messenger bags, and other items, unzip and also feel for an AirTag that’s been placed or sewn in.
• Check belongings: Someone could have posted you an item with an AirTag in it.
• Examine your car: A car may have a number of locations that are unreachable or hard to check. Because an AirTag has as long as a year’s worth of power, someone might wrap it in cotton (to stifle the beep it may make; see below), slit a fabric seam, slip it in, and sew it back up. Parking your car away from homes and businesses and using a Bluetooth scanner can help you pinpoint if one is in your car.

Even if someone doesn’t have access to your home, work, school, or vehicle, and you don’t receive mail at the address at which you live—you might use a P.O. box or another person’s address—someone could ship you an item with an AirTag in it, and when you take that home, they could have your location. If you’re in that specific situation, you may need to examine all packages received elsewhere before bringing them home.

4. Find the AirTag using a Bluetooth scanner

Because AirTag regularly emits Bluetooth signals that Apple devices can pick up, you can use a simple Bluetooth tracker for iOS or iPadOS to scan the area around you and see if an AirTag is nearby. While these tracking apps can’t identify AirTag as such—AirTag changes its Bluetooth ID regularly to avoid being trackable themselves—the apps give you the lay of the landscape. That includes the names of Bluetooth devices that do label themselves in their broadcasts.

BLE Scanner is a limited but free app that provides a list of Bluetooth devices your iPhone or iPad can detect, and offers a mapping feature that roughly sorts them by signal strength into distance away. This is particularly useful if you’re checking out whether a car has a hidden AirTag; less so inside when there may be dozens of your own and neighbors’ devices close enough to register. Regular Bluetooth devices typically identify themselves generically (like my “HP OfficeJet Pro 9010 series” printer) or specifically, as with the sharing name of your Macs, iPhones, iPads, Apple TVs, FitBit trackers, and so on.

Bluetooth BLE Device Finder (free to download, but $4.99 to unlock needed features) has the advantage of letting you drill down into Bluetooth technical details, which may give additional clues about which devices are legitimate and not.

If you can eliminate all known Bluetooth devices, including by powering down equipment that you’re unsure of, and what’s left has no associated name, it can be worth looking further by hand.

How to stop an AirTag tracking you

There are a number of ways you can stop the AirTag from tracking you. We’ll run through them all below including how to find an AirTag in your car and what to do if there is an AirTag detected near you but you can’t find it.

1. Opt out of the Find My network

While you can’t stop other iPhone, iPad, and Mac users from relaying the location of the AirTag, you can at least opt yourself out of the Find My network, though this removes your ability to track your own lost or stolen iPhone, iPad, Apple Watch, Mac, or an AirTag through this extended network. Earlier versions of iOS and macOS don’t include support for the Find My network.

• In iOS 13 or iPadOS 14 or later go to Settings > Account name > Find My > Find My iPhone/iPad, and disable Find My network.
• In macOS 10.15 Catalina or later, go to the Apple ID preference pane, select the iCloud link at left, click the Options button to the right of the Find My Mac item, and uncheck Offline Finding or Find My network (the text varies by macOS version).

2. Get the AirTag’s serial number and associated phone number

If you find an AirTag, you can safely determine more information about it without disclosing to the person who planted it that you’ve done so. The AirTag includes NFC, useful both for pairing the device initially and for letting any smartphone or tablet with an NFC reader pull up a URL from the device. That includes Android phones and other hardware, as it uses an industry standard for NFC encoding. On following the URL, you’re taken to a page that contains the AirTag’s serial number. That page can also show a phone number set by the owner if they marked it lost. The owner isn’t notified in any fashion about the page being loaded, and Apple preserves the owner’s privacy by providing no direct linkage at all.

However, in the case of unwanted tracking, the serial number may help if you pursue civil action, want to obtain a restraining order, or contact law enforcement. Because AirTag tracking requires device pairing, an iCloud account, and an iPhone or iPad that’s logged into the account, anyone actively tracking you is also producing a trail of information stored on their phone, across the cellular network, and in other places.

Apple uses end-to-end encryption to protect the location information sent from an arbitrary device to an iPhone, iPad, or Mac, which has to use the Find My app to view it. But the information isn’t secured in the same way on the device. Police and national investigators would be able to create a close association of logins and access, as well as prove that an AirTag was paired with a specific iPhone or iPad. This may deter abusers and others somewhat if they’re aware of how easily they can be tracked back.

3. Disable the AirTag

Once you’ve found the AirTag and obtained the information you want from it, you don’t need a hammer or rock to disable it. Unlike most of Apple’s hardware, the AirTag has a removable battery.

• Use pressure to rotate the AirTag’s metal underside counter-clockwise (from upper right to upper left).
• Remove that plate.
• Then remove the battery.

What to do if you are being tracked by an AirTag

You probably know already if you’re a candidate for involuntary tracking: someone in your life (or formerly so) or a family member may show up at unexpected times in unexpected places when they have no reason to know you’re there. They may comment in person, via email, or otherwise about your activities or whereabouts. Or you’re in the middle of or long past a nasty break-up of a relationship or marriage or have broken off contact with a parent or family members.

Whatever the case, if you’re in need of help, consult one of these U.S.-based services the National Domestic Violence Hotline or more specialized resources for victims of domestic abuse, stalking, and other violence listed by the National Coalition Against Domestic Violence. Local law enforcement, the FBI, or national police in other countries also offer resources.
