ICO warns major platforms over lack of privacy-friendly age assurance

The UK Information Commissioner’s Office has warned that major platforms have not yet introduced viable and privacy-friendly age assurance measures to stop underage children from accessing services with minimum age limits.

The statement follows letters sent by the ICO in March to TikTok, Snapchat, Facebook, Instagram, YouTube, and X, calling on them to urgently review and strengthen measures to prevent underage children from accessing their services.

Responses from the platforms show that some services are taking, or considering, additional steps to protect children. However, the regulator said none had yet introduced new age assurance solutions that it considers both viable and privacy-friendly.

The ICO said it does not yet have confidence that appropriate measures are being put in place and raised concerns that underage children’s data is still being processed on platforms they should not be able to access.

The regulator warned that more progress is needed and said it is considering next steps, including formal investigations and sanctions. Platforms that set minimum age limits must have effective age assurance measures in place, it added.

The ICO said it will continue working closely with Ofcom, which enforces the Online Safety Act, to ensure underage users cannot access services that were not designed for them. It also said its response to the government’s ongoing consultation sets out how the ICO can act under data protection law.

Why does it matter?

The ICO’s warning shows that age assurance is becoming both a child safety and data protection issue. Platforms that set minimum age limits may face pressure not only to keep younger users away from unsuitable services, but also to avoid unlawfully processing children’s personal data when those users should not have access in the first place.
