The company said on Tuesday it will apply its latest detection tools in 27 European Union countries and also bring the system to Facebook in the US for the first time, with the UK and EU rollout on that platform set to follow in June.

This builds on earlier work to identify teenagers even when they enter false birth dates. Meta has been testing systems that flag accounts it believes belong to younger users and then apply stricter settings automatically.

“This technology will be expanded to 27 countries in the European Union. Meta is also expanding this technology to Facebook in the United States for the first time, with the UK and EU to follow in June,” the company said in a blog post.

Pressure has been growing on technology firms to show how they protect young users. Regulators and parents have complained about harmful content, online abuse and the effect of social media on teenagers.

Meta says it now relies more on artificial intelligence to assess whether an account belongs to a minor. The system does not depend only on the date of birth entered by users. Instead, it reviews activity across profiles.

That includes posts, comments, captions and other signals. For example, references to school life or birthday celebrations may point to a younger age. The company has also added visual analysis, allowing its systems to review images and videos for general age cues.

Meta stressed that the technology is not facial recognition, saying the system looks at broad features, not identity.

If an account is judged to be underage, it may be deactivated, while the user would then need to prove their age to restore access. Meta is also trying to stop repeat attempts by users it believes are below the minimum age.

At the same time, Meta is expanding its “Teen Account” settings. These place limits on who can contact younger users and the type of content they see. Accounts suspected to belong to teenagers are moved into these settings by default.

The company further revealed it has already enrolled hundreds of millions of users into these protections across Instagram, Facebook and Messenger since 2024.

For parents, Meta will begin sending notifications in the US with guidance on how to check a teenager’s age settings. The messages will include advice on discussing honest age reporting online.

“We’re continuing to strengthen our underage enforcement measures by using AI to remove people under 13 from our services.”

Meta added that age verification is an industry problem. It said app stores should take a stronger role by confirming users’ ages and sharing that information with developers.

Driving its own systems, Meta plans to expand the technology further this year, aiming for more global coverage.

The change started on February 24, 2026, as the company also expanded its age-verification tools for developers in Brazil and in two U.S. states, Utah and Louisiana.

The update affects how age categories are shared between users and app developers. Apple said it is rolling out new features through its Declared Age Range API, which is now available in beta.

The tool allows developers to request a user’s age category without accessing personal data such as a date of birth.

In Brazil, developers can use the updated API to obtain a user’s age category. The age category will only be shared if the user, or a parent or guardian where relevant, agrees, while API will also return a signal from the user’s device about the method of age assurance.

Apple confirmed that, from February 24, 2026, it will block downloads of apps rated 18+ in Australia, Brazil and Singapore unless users are confirmed to be adults through reasonable methods.

The App Store will carry out that confirmation automatically. However, Apple noted that developers may still have separate legal duties to verify users under local law.

In Brazil, developers who identify their apps as containing loot boxes through Apple’s age rating questionnaire will see their app ratings updated to 18+ on the Brazil storefront. Lawmakers in the country have spoken about gambling-like features in games.

In the United States, new regulations will take effect in two states. For users with new Apple accounts in Utah from 6 May 2026, and in Louisiana from 1 July 2026, age categories will be shared with developers’ apps when requested through the Declared Age Range API.

Apple said it has expanded its existing tools to help developers meet legal requirements in both states.

These tools include the Declared Age Range API, the Significant Change API under PermissionKit, a new age rating property type in StoreKit, and App Store Server Notifications.

Apple said: “New signals are now available through the Declared Age Range API, including whether age-related regulatory requirements apply to the user and if the user is required to share their age range.

“The API will also let you know if you need to get a parent or guardian’s permission for significant app updates for a child.”

Developers can use the API to present important update notifications to adults in Utah and Louisiana through what Apple calls the Significant Update Action, which remains in beta.

When releasing a significant update, developers must follow Apple’s Human Interface Guidelines and provide a clear description of the changes.

Apple previously worked to meet similar age-assurance requirements in Texas in October last year. It later paused parts of that plan in December after the state law faced a court challenge.

Governments in several countries have introduced stricter age-assurance rules aimed at limiting minors’ access to certain digital services. Apple’s latest changes adjust how its platforms, including iOS, iPadOS and macOS, handle age ratings, permissions and account signals in response to those laws.

For developers, the changes mean closer attention to local regulations. In Brazil, game makers that include loot boxes must now accept an automatic 18+ rating.

In Australia, Brazil and Singapore, 18+ apps will not download until adult status is confirmed. In Utah and Louisiana, age categories will flow directly to apps when requested, provided the user meets the new account conditions.

Apple said the updated tools are designed to give developers a way to meet legal obligations without collecting sensitive personal information.

The company says the feature works in the background, scanning account-level and behavioural signals to judge whether an account is likely run by someone under 18. 

When that threshold is crossed, content limits are switched on automatically. The idea, OpenAI argues, is to give teens a safer version of the product without forcing every user through upfront identity checks.

This is a response to  complaints the company has received over how its tools affect children. OpenAI has been warned by regulators over past incidents involving young users, and this rollout reveals a transition from reactive fixes to a more systemic safeguard.

According to OpenAI, the age prediction system looks at factors such as how long an account has existed, typical usage times, long-term patterns, and the age a user claims when signing up. 

No single signal decides the result. Instead, they are weighed together to reach a probability-based judgement.

When an account is flagged as under 18, ChatGPT applies restrictions around sensitive areas. These include graphic violence, depictions of self-harm, sexual or violent role play, risky online challenges, and content that promotes extreme body ideals or unhealthy dieting. If the system is unsure about someone’s age, it defaults to the safer setting.

OpenAI said in its announcement: “We’re rolling out age prediction on ChatGPT consumer plans to help determine whether an account likely belongs to someone under 18, so the right experience and safeguards can be applied to teens.”

Adults who are wrongly placed into the under-18 experience are not locked out permanently. They can verify their age through Persona, a third-party identity service, by submitting a live selfie and, in some regions, a government-issued ID. OpenAI maintains that it does not receive copies of these documents, only confirmation of age.

The company is also leaning on parental controls, allowing guardians to set usage limits, restrict features such as memory, and receive alerts if signs of serious distress appear. These tools, OpenAI says, are optional but designed to give families more oversight.

The rollout is already live in many regions, with Europe scheduled to follow in the coming weeks due to regulatory requirements. OpenAI says it will monitor how the system performs and adjust it over time, refining which signals are most important and closing gaps where users try to bypass safeguards.

Brussels is pressing these platforms, classified as Very Large Online Platforms (VLOPs) due to their reach of over 45 million EU users, to prove that they are taking real steps to shield children from illegal and harmful content. This includes exposure to drugs, vaping products, and material that promotes eating disorders.

The EU request centres on the companies’ age verification tools and internal measures for restricting harmful material regarding child safety. Officials also want explanations on how their algorithms handle potentially addictive recommendation systems and how app stores manage access to gambling, sexual content, and so-called “nudify” applications.

“Today, alongside national authorities in the member states, we are assessing whether the measures taken so far by the platforms are indeed protecting children,” said EU tech chief Henna Virkkunen.

The case is part of an enforcement under the DSA, the EU’s digital law designed to make tech giants more accountable for content circulating on their platforms. The Commission has issued formal Requests for Information (RFIs), a step that could lead to full investigations and fines reaching up to 6% of global turnover if breaches are confirmed.

Beyond enforcement, the EU is exploring policy changes, including setting a bloc-wide “digital age of majority” that could restrict minors’ access to certain online services, an idea inspired by Australia’s under-16 social media ban.

In the United States, several states such as Utah and Arkansas now require parental consent for minors to use social media. Meanwhile, within Europe, Denmark is pushing for a national social media ban for users under 15, while France and Spain have publicly backed tighter digital age limits.

The EU child safety investigation follows its child protection guidelines published in July 2025, which laid out clearer expectations for compliance with the DSA.
