What Is an AirTag? Everything You Need to Know in 2026

Apple’s AirTag has become one of the most popular ways to keep track of everyday items like keys, wallets, backpacks, and luggage. If you’ve heard the term but aren’t sure exactly what it does or how it works, this guide breaks down everything about AirTags, including the newly released second-generation model.

What Is an AirTag?

An AirTag is a small, coin-sized tracking device made by Apple that helps you locate personal belongings using the Find My app. You attach an AirTag to an item, such as a keychain, bag, or wallet, and it uses Bluetooth and Apple’s global Find My network to show you the item’s location on a map.

Apple first launched the original AirTag in April 2021. Nearly five years later, on January 26, 2026, Apple officially released a second-generation AirTag, which most people are already referring to as “AirTag 2,” even though Apple did not formally give it a numbered name.

How Does an AirTag Work?

AirTags don’t rely on GPS or a cellular connection of their own. Instead, they use a combination of technologies:

• Bluetooth: The AirTag sends out a secure Bluetooth signal that nearby Apple devices can detect.
• Find My Network: Millions of iPhones, iPads, and Macs around the world anonymously and privately relay the AirTag’s location back to its owner, all without draining battery life or compromising anyone’s privacy.
• Ultra Wideband (UWB): On compatible iPhones and Apple Watches, AirTags support Precision Finding, which gives you exact distance and direction to the item using on-screen arrows and distance readouts.

Because it taps into the massive Find My network rather than needing its own connectivity, an AirTag can be located almost anywhere, even if it’s far from its owner’s devices.

What’s New With the Second-Generation AirTag (2026)

Apple’s new AirTag, released this January, brings a handful of meaningful upgrades over the original:

Longer Precision Finding Range The new AirTag uses Apple’s second-generation Ultra Wideband chip, the same chip found in the iPhone 17 lineup, iPhone Air, Apple Watch Ultra 3, and Apple Watch Series 11. This boosts Precision Finding range by up to 50 percent compared to the original AirTag.

Louder Speaker Apple also redesigned the internal hardware to make the new AirTag’s built-in speaker 50 percent louder, with a distinctive new chime, making it easier to locate items by sound in situations where Precision Finding isn’t practical.

Expanded Precision Finding Compatibility The new AirTag also brought Precision Finding support to the Apple Watch Series 9 and Apple Watch Ultra 2, along with newer models in those families, closing a gap that had existed since those watches launched with U1 chips. It’s worth noting that the iPhone 16e and Apple Watch SE still lack Ultra Wideband hardware entirely, so Precision Finding isn’t available on those devices with either AirTag generation.

More Sustainable Materials The redesigned AirTag is manufactured using 85 percent recycled plastic.

Share Item Location Integration The new AirTag works with Apple’s Share Item Location feature, which lets travelers share a tracked bag’s location with airlines to help recover lost luggage faster.

AirTag Pricing

Apple kept pricing the same with the new generation:

• Single AirTag: $29
• Four-pack: $99

Both the original and new AirTag are sold at this same price point, and Apple did not introduce a price increase alongside the hardware update.

How to Set Up an AirTag

1. Remove the plastic tab to activate the battery.
2. Hold the AirTag near your iPhone.
3. Tap “Connect” when the setup card appears on screen.
4. Name the AirTag (for example, “Keys” or “Backpack”) or create a custom label.
5. Attach it to your item using an official or third-party AirTag holder, keychain, or adhesive mount.

Common Uses for AirTags

• Tracking keys, wallets, and bags
• Keeping tabs on luggage while traveling
• Finding misplaced items around the house
• Attaching to bikes, backpacks, or other valuables
• Helping locate items left behind in rideshares or public spaces

AirTag Privacy and Safety Features

Because AirTags could theoretically be misused to track a person without their knowledge, Apple has built in several safety protections:

• Unwanted tracking alerts: iPhones automatically notify users if an unknown AirTag appears to be traveling with them over time.
• Audible alerts: An AirTag separated from its owner for an extended period will play a sound to alert anyone nearby.
• Android support: Apple offers a free “Tracker Detect” app so Android users can also scan for nearby AirTags that may be traveling with them.

These features have been present since the original AirTag and remain in place with the new second-generation model.

AirTag vs. Original AirTag: Should You Upgrade?

If you already own the original AirTag, the upgrade may not be essential unless you specifically want the extended Precision Finding range or the louder speaker. However, if you’re buying trackers for the first time, the new AirTag is the better long-term choice since it uses the newer UWB chip and will likely receive future software support for longer.

Final Thoughts

AirTags remain one of the simplest and most reliable ways to keep track of everyday items, and the newly released second-generation model makes an already useful product even more precise and easier to locate. Whether you’re new to Apple’s ecosystem or upgrading from the original, AirTags are a small investment that can save you from the stress of a lost bag, wallet, or set of keys.
