AirTag anti-stalking alerts explained for parents

After AirTags were misused to follow people, Apple added protections so that anyone carrying a tag they did not know about would find out. Since 2022 Apple has said AirTag is meant for belongings, not people.^[10] When it launched the second-generation AirTag in January 2026, Apple described it as “designed exclusively for tracking objects, and not people or pets.”^[9]

How an AirTag finds its location, and why that matters for a child who wanders, is covered in AirTag for kids: can you use one to track your child? This page is about the alerts: what other people see, when the tag makes noise, and what you control.

When an AirTag that is separated from its owner is seen moving with someone’s iPhone over time, that iPhone shows an alert called “AirTag Found Moving With You”. Other Find My accessories show “[Product name] Found Moving With You” or “Unknown Accessory Detected”.^[1] The alerts need iOS 14.5 or later, with Bluetooth, Location Services and tracking notifications on and airplane mode off. From iOS 17.5, iPhones also alert to compatible trackers from other companies.^[2]

Tapping the alert gives the person a set of tools:^[1],[2]

• Play Sound to make the tag chirp, as many times as they like.
• Find Nearby (Precision Finding) on a supported iPhone, which gives distance and direction to the tag.
• Owner details. Holding a phone near the white side of the AirTag opens a web page with its serial number and the last four digits of the owner’s phone number.
• Instructions to Disable. Apple says that once the item is disabled, the owner can no longer get updates on its current location.

Phones running Android 6.0 or later get unknown tracker alerts for AirTags, for tags on Google’s Find Hub network and for some earbuds. Google says alerts are not instant: one comes only after the person has moved with the tracker over time, at most once per tracker per day.^[3]

Anyone can also look on demand: under Settings, Safety and emergency, Unknown tracker alerts, a Scan now button searches for about 10 seconds and lists nearby trackers that are away from their owners. From there the person can play a sound on the tag, which Google says does not notify the owner, read the AirTag’s details by holding it to the back of the phone, and follow the steps to disable it.^[3]

On 13 May 2024, Apple and Google launched cross-platform alerts based on a joint industry specification called Detecting Unwanted Location Trackers, with support in iOS 17.5 and Android 6.0 and later. Chipolo, eufy, Jio, Motorola and Pebblebee committed to making their future tags compatible.^[4] The work was taken to the Internet Engineering Task Force (IETF) to become an official standard.

One honest correction to what you may read elsewhere: as of October 2026 there is no finished standard. The IETF draft describing how tags must behave expired in 2025 without becoming an RFC, and the working group is still active.^[5],[6] The draft is still the clearest public description of the rules, and it explains why the alerts behave the way they do:^[5]

• About 30 minutes away from the owner’s phone and the tag switches to “separated” mode.
• Its Bluetooth identity changes every 15 minutes near the owner, but only every 24 hours when separated, so that a stranger’s phone can notice the same tag staying with it.
• After a random 8 to 24 hours in separated mode, the tag starts listening for motion and plays a sound when it is moved. It keeps sounding with movement for up to ten sounds or 20 seconds, rests for six hours, then starts again.
• Reconnecting with the owner’s phone resets all of this.

These timings come from the draft, not from Apple or Google. Neither company publishes its exact settings, and they may differ.

If you hear an AirTag chirp, one of these is usually the reason:

• Someone played a sound on it. That might be you or a family member in Find My, or a person who got an alert on their phone.^[1],[3]
• A battery was just put in, or the tag was reset. Apple says you will hear a sound when a new battery connects.^[11]
• It has been away from its owner and was moved. This is the anti-stalking sound. Apple’s words: any AirTag separated from its owner for a period of time makes a sound when moved, to notify those nearby.^[2]

The second-generation AirTag is louder. Apple says it is 50 percent louder than the first and can be heard from up to twice as far away.^[9]

The alerts assume that a tag away from its owner and moving with someone else may be following them. An AirTag on a child creates exactly that situation whenever the child is somewhere you are not.

A school day

Your child goes to school with an AirTag in their backpack and your phone goes to work with you. By the draft’s rules the tag is “separated” within about half an hour. Over the day, the phones of an aide, a teacher or the bus driver may show an alert that an unknown AirTag is moving with them. Some will reasonably go looking for it. A quiet word with the school helps, and our free school safety plan is a good place to write it down, but it cannot stop the alerts.

Overnight and longer stays

Respite weekends, camp, a night at a grandparent’s or time with a co-parent can run past the 8 to 24 hour window, and then the tag can start to chirp whenever it moves. For a child with sensory sensitivities, a sudden noise from inside their bag or coat may be upsetting. (That is our reasoning, not a sourced finding.)

The day your child wanders

Here the design works directly against you. The person your child ends up with is the person the alerts are built to protect. If they get an alert, they can find the tag and are shown how to disable it. From your side, the tag simply stops updating.^[1] Most people who find a lost child are trying to help, but the tools work the same for anyone.

You can share an AirTag in Find My with up to five other people, and Apple says the people you share it with do not get tracking notifications when it moves with them. Everyone needs iOS 17 or later, an Apple Account with iCloud, and iCloud Keychain on. Apple also says you cannot share an item with a child account.^[7] In the US and Canada that generally means any Apple Account a parent created for a child under 13.^[8]

Someone in your Family Sharing group who borrows the tag can also turn its alerts off for one day or indefinitely, from the alert on their own device.^[1]

None of this is a flaw in AirTag. It is very good at finding keys and bags, and the alerts protect people. The problem is asking it to do a job it was designed to resist. If you need to locate a child who wanders, these are the questions worth asking of any device, ours included:

• Does it find its own position with GPS, rather than waiting for strangers’ phones?
• Does it report on its own over a cellular connection, so it works when you are not nearby?
• Does it alert you when your child leaves a safe area, so you hear in the first minutes rather than finding out later?
• Is it made to be worn by a child, comfortably enough that they will keep it on, instead of being made to be found and switched off?
• Will the school allow it? Some schools ban devices that can listen or record.
• What does it cost over a few years, including the monthly plan?

Our guide to choosing a GPS tracker for an autistic child compares Bluetooth tags, smartwatches and dedicated trackers against these questions. If you are caring for a parent rather than a child, AirTag vs a real GPS tracker for someone with dementia covers the same alerts from that side. And whatever you choose, a written wandering safety plan matters more than any device.
