UK regulator Ofcom has launched an investigation into TikTok's age verification systems, citing serious concerns about the platform's reliance on 'age inference' methods. This approach attempts to identify users under 18 by analysing behavioural patterns, but Ofcom has found evidence that it fails to accurately detect significant numbers of children, exposing minors to potentially harmful content. The investigation operates under the Online Safety Act, which requires platforms to implement effective age assurance mechanisms.

The probe intensifies regulatory pressure on TikTok ahead of an impending UK ban on social media for under-16s, mirroring legislation already passed in Australia. Violations could trigger penalties of up to £18 million or 10% of worldwide revenue. Though TikTok maintains it provides over 50 safety and privacy features for younger users, regulators have determined that behavioural analysis falls short of industry standards for robust age verification. Broader enforcement shows progress, with platforms increasingly adopting more reliable age-checking technologies.
