How to Scan AirTags on iPhone

AirTags are small, coin-shaped Bluetooth trackers made by Apple that attach to your keys, bag, or other belongings, letting you find them through the Find My app. To scan an AirTag with your iPhone, simply bring your iPhone near the AirTag and hold it close—a notification will appear on your screen, and you can tap it to see the AirTag’s serial number and confirm it’s yours. If you’re trying to scan an AirTag that isn’t yours (or one you just found), the same proximity detection works, but you’ll see an alert saying the AirTag is separated from its owner, along with instructions to disable it.

What Are AirTags and How Do They Work?

AirTags were introduced by Apple in April 2021 as a direct competitor to Tile trackers. Each AirTag contains a Bluetooth chip, a U1 ultra-wideband chip (in the standard version), and a replaceable CR2032 battery that lasts about a year. The AirTag itself has no GPS; instead, it relies on the vast network of Apple devices—iPhones, iPads, and Macs—to relay its location. When your AirTag is out of Bluetooth range, it emits a secure Bluetooth signal that nearby Apple devices pick up and anonymously send to iCloud, updating its location in the Find My app. This is why AirTags work so well even when your item is miles away: they piggyback on the billions of Apple devices already in use.

The U1 chip in AirTags enables Precision Finding, which uses ultra-wideband technology to show you the exact distance and direction to your AirTag when you’re within about 30-50 feet. Your iPhone displays an arrow pointing toward the AirTag, with a distance readout like “12 feet” that updates as you move. This works only on iPhones with the U1 chip (iPhone 11 and later, except the iPhone SE 2nd and 3rd gen, which lack U1). Older iPhones can still use AirTags, but they’ll only get a general distance indicator, not the arrow.

How to Scan an AirTag with Your iPhone

Scanning an AirTag is a simple process, but there are a few scenarios where you might need to do it. Here’s how it works in each case:

1. When you first set up a new AirTag: Pull the plastic tab out of the AirTag to activate the battery, then hold it near your iPhone. A “Connect” animation appears on the screen—tap Connect, and you’ll be asked to name the AirTag (e.g., “Keys” or “Backpack”) and assign it to your Apple ID.
2. When you want to check an AirTag’s serial number: Hold the AirTag against the top of your iPhone (the same area used for NFC payments). A notification pops up showing the serial number and a link to the Find My app. This works only if the AirTag is in Lost Mode or has been disconnected from its owner.
3. When you find an AirTag that isn’t yours: If you hold your iPhone near an unknown AirTag, you’ll get an alert saying “AirTag Found Moving With You” or “Unknown AirTag Detected.” Tapping it shows the serial number and instructions to disable it (by removing the battery). This is part of Apple’s anti-stalking measures.
4. When you want to trigger a sound: In the Find My app, go to the Items tab, select your AirTag, and tap “Play Sound.” The AirTag beeps loudly, helping you locate it by ear. You can also ask Siri: “Hey Siri, where are my keys?”

Note that scanning an AirTag with your iPhone requires iOS 14.5 or later, and your iPhone must have Bluetooth and NFC enabled. The NFC scan works even if your iPhone’s battery is low, as long as the phone is on.

How to Set Up and Use AirTags on iPhone

Setting up an AirTag takes less than a minute. After you pair it, it appears in the Find My app under the Items tab. From there you can:

• See its last known location on a map, with a timestamp.
• Put it in Lost Mode—this locks the AirTag to your Apple ID and lets you leave a contact message that appears if someone scans it.
• Share the AirTag’s location with family members or friends (iOS 17 and later) so they can help find it.
• Replace the battery—the CR2032 battery lasts about a year; you’ll get a low-battery notification in the Find My app.

One useful trick: if you’re in a crowded place and your AirTag is out of Bluetooth range, you can enable “Notify When Found” in the Find My app. You’ll get a notification the moment any Apple device detects your AirTag, which is often how people recover items left in taxis or on public transit.

Common AirTag Scanning Problems and Fixes

If your iPhone doesn’t recognize an AirTag, try these steps in order:

1. Make sure Bluetooth is on—go to Settings > Bluetooth and toggle it off and on. AirTags rely on Bluetooth for the initial connection.
2. Check that NFC is enabled—for the serial number scan, NFC is usually always on, but if you’ve disabled it in Settings > General > NFC, re-enable it.
3. Restart your iPhone—this clears temporary glitches that can block the pairing animation.
4. Reset the AirTag—press down on the stainless steel back, rotate it counterclockwise, and remove the battery. Wait 5 seconds, reinsert the battery, and press until you hear a chime. Then hold it near your iPhone again.
5. Update iOS—AirTags require iOS 14.5 or later, and older iOS versions may have bugs that prevent scanning. Check Settings > General > Software Update.

If you’re trying to scan an AirTag that was previously paired to someone else, you won’t be able to pair it to your iPhone until the original owner removes it from their Apple ID. The Find My app will tell you this. If you’ve bought a used AirTag and the owner can’t remove it, you can still use it with Android via third-party apps, but it won’t work with Find My.

AirTags vs. Other Trackers

AirTags are often compared to Tile trackers, Samsung SmartTags, and Chipolo. Here’s how they stack up:

• AirTag—Best for iPhone users. Uses Apple’s Find My network, which is the largest tracking network in the world. Precision Finding with U1 chip. No Android app support (though Apple released an Android app in 2024 to detect unknown AirTags).
• Tile—Works with both iOS and Android, but the network is smaller. No ultra-wideband on most models. Subscription required for some features like location history.
• Samsung SmartTag2—Works only with Samsung Galaxy phones. Uses Samsung’s SmartThings Find network, which is large but not as big as Apple’s.
• Chipolo One Spot—Works with Apple’s Find My network, so it’s compatible with iPhones, but lacks the U1 chip for Precision Finding.

For most iPhone users, AirTags are the obvious choice because of the network effect. But if you have an Android phone, you’ll need a Tile or a Samsung SmartTag (if you have a Galaxy).

Safety and Privacy Concerns

AirTags have been criticized for potential misuse in stalking, since they’re small and easy to hide. Apple has added several safeguards:

• Unknown AirTag detection—If an AirTag that isn’t yours is moving with you, your iPhone will alert you after a few hours (or sooner if you’re at home). The alert says “AirTag Found Moving With You” and shows the serial number.
• Sound alerts—If an AirTag is separated from its owner for more than 8-24 hours (the timing varies), it plays a sound to alert anyone nearby.
• Android app—Apple released a free Android app called “Tracker Detect” that lets Android users scan for nearby AirTags.
• Precision Finding for unknown AirTags—On iPhone 11 and later, you can use Precision Finding to locate an unknown AirTag that’s moving with you, even if you don’t know where it is.

If you receive an alert about an unknown AirTag, don’t panic. Check your belongings—especially coats, bags, and vehicles—and if you find the AirTag, you can disable it by pressing down on the back and rotating counterclockwise to remove the battery. Then contact local law enforcement if you feel threatened.

Frequently Asked Questions

Can I scan an AirTag with an Android phone? Yes, but not with the same ease. Apple’s “Tracker Detect” app (available on Google Play) lets you scan for nearby AirTags, but you can’t pair or use an AirTag with Android for tracking your own items. The app only detects unknown AirTags to prevent stalking.

How do I know if an AirTag is near me? Your iPhone will automatically alert you if an unknown AirTag is moving with you. You can also manually scan by opening the Find My app, tapping the Items tab, and looking for “Items Detected With You” at the top of the screen. This shows any AirTags that have been traveling with you for a while.

Can I use an AirTag without an iPhone? No, AirTags are designed to work exclusively with Apple devices. You need an iPhone, iPad, or Mac to set them up and use the Find My app. There’s no web interface for AirTags.

What’s the range of an AirTag? Bluetooth range is about 30-50 feet (10-15 meters) in open air. Beyond that, the AirTag relies on the Find My network, so it can be located anywhere in the world as long as any Apple device passes nearby. Precision Finding works within about 30-50 feet and only on iPhones with the U1 chip.

Do AirTags work with the iPhone SE? Yes, all iPhone SE models (1st, 2nd, and 3rd gen) work with AirTags, but they don’t have the U1 chip, so you won’t get Precision Finding. You’ll still see the AirTag’s location on a map and can play a sound.

How do I reset an AirTag to sell it? Open the Find My app, go to Items, select the AirTag, and swipe up to tap “Remove Item.” This unpairs it from your Apple ID. Then press down on the back, rotate counterclockwise, and remove the battery. Reinsert the battery and hold it near a new iPhone to pair it again.
