Meta expands AI age detection to place more teens in Teen Accounts

Meta says it is expanding its AI-based age-estimation technology to Instagram around the world, so that millions more teenagers are placed in Teen Account protections even if they entered an adult birthday. The company announced the change in a post on its newsroom. The claims below are Meta's; NextFish has not independently verified how well the technology works, and Meta has published no accuracy or error-rate figures in the coverage we reviewed.

What is Meta changing?

Meta says Teen Accounts on Instagram, Facebook and Messenger automatically limit who can contact teens, the content they see and their time on the apps. Placing teens in those protections depends on knowing their age, which Meta calls an industry-wide challenge because some teens misrepresent their age online. It says it uses AI to find people it suspects are teens, including those who use an adult birthday, and places them in Teen Account protections.

Citing encouraging results since it first introduced the technology, Meta says it is now expanding it globally on Instagram and continuing to roll it out on Facebook. Later this year, it says, it will begin launching similar technology globally on Threads. The post does not say how many accounts are affected beyond "millions more."

Meta says the expansion follows commitments it made in a recent agreement with 52 bipartisan attorneys general to improve how it identifies teens and children under 13.

How does this build on earlier steps?

The expansion follows earlier ones. According to Thurrott's report on an earlier Meta announcement, Meta began using AI last year to find likely teen accounts in the United States, Australia, Canada and the United Kingdom, then said it would start applying the technology on Instagram across 27 EU countries plus Brazil, with Facebook measures reaching the US and a UK and EU rollout to follow in June. Meta said it aimed to expand globally on Instagram throughout the year. In June 2026, Business Today reported that Meta's 13+ content settings for Teen Accounts were rolling out globally across Instagram, Facebook and Messenger.

Meta describes the system as looking beyond a user's self-declared age. Business Today reports that it analyses signals across posts, comments, bios and captions, such as birthday celebrations or school-grade mentions, and adds visual analysis of general cues, for instance height or bone structure, to estimate age. Meta says this is not facial recognition and does not identify the specific person.

According to Thurrott, Meta also said it was making it easier to report suspected underage accounts and would use AI-driven review to supplement its human review teams. In its own testing, Meta says, AI-driven review is more accurate and resolves reports faster than human review alone; that is Meta's claim, and no independent figure was published. Thurrott noted that the changes followed a call from the EU Commission for Instagram and Facebook to do more to remove underage users.

What is Meta arguing about app stores?

In Australia, Meta says it has begun using Apple's age-range signal. When a parent sets up a phone for a teen, the app store can confirm the user's age range, and Apple passes that range to developers such as Meta each time the teen downloads an app.

Meta says it uses the signal voluntarily, but argues that while collecting and sharing it is optional for app stores and using it is optional for developers, teens will get uneven protection from one app to the next. It says it has long supported legislation requiring age verification and parental consent at the app-store level, and that one verified signal from devices, shared consistently with all apps, would be far more effective and privacy-preserving than having each platform verify age on its own. It adds that age estimation by developers like Meta can serve as a backstop. This is Meta's position in an ongoing policy debate; Apple's view is not part of Meta's post.

What is Meta asking of others?

Meta says many national laws on teen online safety do not explain how companies should determine age: some require invasive checks for everyone, while others offer no guidance. It argues that unless other companies follow its standard, teens remain inconsistently protected, and it calls on TikTok and YouTube to adopt the same practices. This month, Meta says, US parents will start to see a video in their Instagram feed explaining its approach, linking to an article by Larry Magid, an internet safety advocate and the president and CEO of ConnectSafely, describing Meta's "multi-layered age assurance approach."
