- AirTag 1代: The text on the back is “Assembled in China” and “Designed by Apple” (in English upper and lower case)
The remaining changes are in the internal antenna module and sound design, mainly to support new chips and sound effect upgrades.
Packaging box differences

List of highlights of AirTag 2 specifications upgrade
1. Equipped with second generation UWB chip
AirTag 2 uses the second-generation U2 ultra-wideband chip, which can “accurately search” to achieve more advanced functions. The specific performance is as follows:
- The furthest range can reach approximately 60 meters (1.5 times larger than the previous generation)
- Direction and distance guidance are more accurate and stable
- Bluetooth connection performance is simultaneously upgraded
- Even if the distance is further away, surrounding Apple devices can assist in reporting the location, enhancing the recovery rate of lost items.
2. Support precise search on Apple Watch for the first time
AirTag 2 can not only be paired with iPhone and iPad, this time it also supports Apple Watch’s precise search function. Applicable models include:
- Apple Watch Series 9
- Apple Watch Ultra 2
Users can directly use the vibration prompts, sound effects and screen guidance on the watch to find lost objects without taking out their mobile phones, greatly improving the practicality of wearable devices.
3. The sound prompts have evolved, and the volume has been increased by 50%.
The built-in speaker volume of AirTag 2 is increased by 50%, and it is equipped with a new design prompt sound effect. Even if the distance is far away, the sound can still be heard clearly, helping to determine the direction and distance of objects.
4. Privacy and security are further upgraded, and the anti-tracking mechanism is more complete
The new version of AirTag 2 introduces protective measures such as regularly changing Bluetooth identification codes and cross-platform warning prompts to protect users’ personal information and security against the risk of unauthorized tracking.
AirTag 2 also adds a “share location” function in lost mode, allowing users to temporarily share the location of the AirTag with a third party. In situations such as lost luggage and travel companions assisting in finding the item, the object tracking permissions can be shared with airline customer service or travel companions.
Apple has partnered with more than 50 airlines to help find lost luggage through exclusive links, especially designed for international travelers.
6. Software compatibility requires iOS 26. or above.
The function of AirTag 2 depends on the support of the new operating system. Please ensure that the device has been updated before use, and all devices need to log in to Apple ID and turn on the “Search” function.
- iPhone/iPad: Requires iOS 26.2.1 or iPadOS 26.2.1
- Apple Watch: requires watchOS 26.2.1

Buying Guide: How to choose between AirTag 2 and AirTag 1?
If you are still considering which generation of AirTag to buy, the focus of your choice is not on the basic tracking function, but mainly on the differences in usage scenarios and needs. Moreover, both generations of products rely on the “find” network to provide long-distance positioning updates, have similar battery life, and support the same set of accessories. Therefore, in terms of general tracking needs, no one has obvious advantages.
Who is suitable to buy AirTag 2?
The second generation AirTag is more suitable for people who often need precise positioning and will be more helpful. The upgraded U2 ultra-wideband range can make it easier to find the exact location of items.
It also has a louder speaker, which can also improve the listening effect in noisy environments, or when it is left in a bag or suitcase. It also supports Apple Watch’s precise search function, which makes it more convenient even if you don’t often take your phone out.
Who is suitable to buy AirTag 1?
As for the first-generation AirTag, it is still quite practical for most daily uses, such as simply tracking keys, backpacks, or small items that are easily lost at home.
If you are looking for cost-effectiveness, do not need to use long-distance accurate search, do not use Apple Watch positioning, or just want to get the AirTag search function at the lowest cost, the old model is still a good value for money.
