TikTok to deploy AI age-detection across Europe amid scrutiny

TikTok said it will begin rolling out an AI-driven age-detection system across Europe "in the coming weeks" after a year-long pilot, seeking to identify accounts that may belong to children younger than the platform’s minimum permitted age of 13. The system, built specifically for European rules and developed in consultation with Ireland’s Data Protection Commission, examines profile information, posted videos and behavioural signals to estimate whether an account holder is likely under 13.

Rather than automatically banning flagged users, the company said specialist human moderators will review accounts identified by the technology. TikTok also said it would notify users in Europe about the measures and provide information on next steps. The year-long pilot, centred on the UK and used as the basis for the wider deployment, reportedly led to the removal of "thousands" of accounts believed to belong to children under 13.

TikTok described the rollout as part of a multi-layered age-assurance approach intended to keep under-13s off the platform and to offer age-appropriate experiences to teens. The company said the initial deployment will cover the European Economic Area as well as the UK and Switzerland. The announcement comes as lawmakers and regulators across Europe intensify scrutiny of how social platforms verify users’ ages under the EU’s Digital Services Act and related child-protection debates.

For appeals against age determinations or account removals, TikTok plans to use third-party verification tools, including facial-age estimation supplied by the verification provider Yoti, alongside other methods such as credit-card checks and government-issued identification. The company acknowledged the technical and ethical complexity of such measures, saying that "there remains no globally agreed‑upon method for effectively confirming a person’s age in a way that also preserves their privacy."

Privacy advocates and some legal experts have warned that systems which analyse videos and behavioural patterns risk being invasive and raise questions about how long data will be retained and for what purposes. Regulators, including Ireland’s Data Protection Commission, will be watching implementation details closely to assess compliance with EU privacy rules and data minimisation obligations. TikTok has not disclosed specific accuracy rates, the precise signals used, data-retention periods or granular moderation procedures beyond the use of specialist reviewers and third-party verification for appeals.

The move follows a broader industry trend in which major platforms have experimented with age-verification technologies, often encountering legal, technical and public-resistance challenges. Analysts say an effective, privacy-respecting age-assurance framework could strengthen TikTok’s regulatory standing in Europe, while technical failures, data-protection breaches or sharp public pushback could prompt calls for tougher restrictions or national measures that limit youth access.

As TikTok begins its phased rollout, the questions that remain are technical and policy-oriented: how well the AI will distinguish minors from adults in culturally diverse contexts, how third-party verification will be governed, and whether the system will meet regulators’ expectations for privacy and proportionality. Observers will be looking for detailed technical documentation, regulator rulings and national variations in implementation as the company moves from pilot to full deployment.
