Meta is expanding its artificial intelligence-powered age detection technology worldwide on Instagram to identify teenagers who may have used an adult date of birth when creating their accounts.
The system will assess accounts for signs that users are under 18 and automatically apply Instagram’s Teen Account protections where necessary. This means teenagers may be placed under age-specific restrictions even if they have registered as adults.
Meta announced the expansion on November 9, saying the move is part of its efforts to improve safety for younger users across its platforms. The company is increasingly relying on artificial intelligence to identify accounts where the registered date of birth may not reflect the user’s actual age.
The development comes as Meta faces legal challenges and growing scrutiny over the impact of social media on children and teenagers.
How Instagram’s AI Age Detection Works
Instagram’s age detection technology examines information available across user profiles and account activity to estimate whether someone may be under 18.
According to Meta, its systems look at posts, comments, biographies and captions for details that could indicate a user’s age. These include references to school grades, birthday celebrations and other age-related information.
The technology also analyses photos and videos. Meta says it can assess general physical characteristics, including height and bone structure, to help estimate whether an account holder is a teenager.
By combining these signals, Instagram aims to identify underage users who may have entered an incorrect date of birth during registration.
Meta says its visual analysis does not involve facial recognition or the creation of biometric faceprints. Instead, the technology looks for broader visual patterns that may help estimate age.
Instagram to Apply Teen Account Restrictions Automatically
Accounts identified as potentially belonging to teenagers will receive protections under Instagram’s Teen Account system.
The settings are intended to limit unwanted contact and give younger users greater privacy when using the platform.
The main protections include:
- Private accounts: Teenagers’ accounts are set to private by default, limiting access to their content.
- Restricted direct messages: Teen users can receive messages only from people they follow or are already connected with.
- Comment filtering: Instagram limits exposure to potentially harmful or inappropriate comments.
- Additional safety settings: Age-appropriate restrictions help provide a more controlled experience for younger users.
These protections will also apply to accounts where Instagram suspects that the user has provided an inaccurate date of birth.
Meta Extends Age Detection to Facebook and Threads
Meta is also rolling out age-estimation technology on Facebook and plans to introduce a similar worldwide expansion on Threads later in 2026.
The company wants to identify more users between the ages of 13 and 17 and ensure they receive protections designed for teenagers.
It is also improving its systems to detect accounts that may belong to children under 13, who are generally not allowed to register for standard accounts on its platforms.
The wider rollout reflects Meta’s efforts to make age identification less dependent on information users provide themselves.
Meta Faces Legal Pressure Over Teen Safety
The expansion comes as Meta faces mounting legal pressure in the United States over allegations that its platforms have harmed young users.
In August 2026, the company reached agreements involving 52 bipartisan attorneys general representing US states, territories and the District of Columbia. The settlements were reported to be worth up to $18 billion and included commitments to strengthen protections for children and teenagers.
The legal action raised concerns about the effects of social media on young people’s wellbeing and the adequacy of existing safeguards.
As part of its latest efforts, Meta also plans to show US parents an Instagram video explaining how the platform identifies teenage accounts and applies age-appropriate settings.
The company says it will continue improving its age detection systems as it expands Teen Account protections across Instagram, Facebook and Threads.
