Microsoft is integrating age verification directly into Windows 11, allowing applications to access users' age ranges (e.g., 13-15 or 18+) without disclosing their actual birthdays. This is facilitated through new system-level APIs, specifically the GetUserAgeRangeAsync function, which returns one of five defined age ranges: Under 10 (0-9), 10-12 (10-12), 13-15 (13-15), 16-17 (16-17), and 18+ (18 and above). Another API, GetAgeVerificationStatusAsync, indicates whether the age was independently verified with statuses like Verified, Unverified, OptedOut, TemporarilyUnavailable, or NotApplicable. Microsoft validates the identity of the calling app to ensure security, limiting access to these age signals. This initiative aligns with regulatory demands for enhanced child safety measures in regions like the UK, EU, and U.S., where states are moving toward operating-system-level mandates for age verification.
