Regulatory testing of AirTags for the Federal Communications Commission commenced in 2019 and code began appearing in iOS 13 in June of that year. Official testing reports were issued in September and October 2020.
On February 10, 2022, Apple announced revisions to its Find My software to discourage misuse of AirTags for stalking purposes. As AirTag owners are identified by their Apple ID, the safety features allowed Apple to cooperate with law enforcement, leading to the arrest of a man who had been misusing an AirTag in violation of a protection-from-abuse order in Pennsylvania.
