What to know about the AirTag 4 Pack

AirTag is Apple's small tracker you drop in a bag, on a key ring or in a suitcase and find again in the Find My app. This page links to the AirTag 4 Pack (2nd Generation), released in January 2026.

AirTag 2 vs 1: Apple says the new model uses its second-generation Ultra Wideband chip (the same as the iPhone 17 lineup). Precision Finding can guide you from up to 50% farther away, and the speaker is 50% louder, audible from up to twice as far. For the first time, Precision Finding also works on Apple Watch (Series 9 or later, or Ultra 2 or later). The shape is unchanged, so first-generation accessories still fit.

Each AirTag is 31.9 mm across and 8 mm thick, weighs 11.8 g and is IP67 rated (up to 1 m for 30 minutes). It runs on a user-replaceable CR2032 coin cell that lasts more than a year depending on use. When travelling, Share Item Location lets you send a bag's location to a participating airline.
