Brazil study maps age assurance practices across 25 digital services

A new study by CGI.br and NIC.br examines how digital services in Brazil implement age assurance measures. Presented in Brasília during an event on the Digital Child and Adolescent Statute (ECA Digital), the study reviewed 25 popular online services used by children and adolescents.

The study found that most of the services analysed do not apply age checks at the point of registration, including some platforms aimed at adults. According to the release, age assurance usually appears later, when users try to access specific features such as livestreaming or monetisation.

Titled ‘Age assurance practices in 25 digital services used by children in Brazil’, the study analysed governance documents published before the ECA Digital entered into force. From 18 March, the law requires information-society services aimed at children and adolescents in Brazil, or likely to be accessed by them, to adopt effective age-assurance measures and parental supervision.

The study found that 11 of the 25 platforms relied on third-party age-assurance services, particularly social media and generative AI platforms. Official identity document submission was the most common verification method, while selfie-based checks were the most common age-estimation tool. Differences were also found between the minimum ages stated by services and those listed in app stores, and some adult-oriented platforms could still be accessed by younger users with parental consent.

Parental supervision tools were available in 15 of the 25 services, but activation was usually optional and depended on parents or guardians. Transparency also emerged as a weakness: only six services published Brazil-specific reports, and only one explained how its minimum-age policy was applied. Policies were often spread across multiple pages, averaging 22 pages per service, and around 40% of the services provided related information in other languages.

Fábio Senne, General Research Coordinator at Cetic.br | NIC.br, said: ‘One of the study’s central aims was to verify the integrity of the information made available by digital services in Brazil. It is essential that data on age protection be communicated clearly and accessibly, allowing more informed and effective parental supervision.’

Juliana Cunha, manager of the Digital Public Policy Advisory Office at CGI.br | NIC.br, said: ‘This survey was developed to support the debate on implementation of the ECA Digital and to offer a clear understanding of the current landscape. This initiative forms part of a broader set of actions by CGI.br and NIC.br aimed at providing technical evidence to support effective enforcement of the law. Our commitment is to foster a safer and more responsible digital ecosystem for children and adolescents in Brazil.’

The release says the study used as a methodological reference the OECD technical paper ‘Age assurance practices of 50 online services used by children’, published in 2025. Information was collected between 10 and 30 January 2026 from public documents made available by the services in Brazil, totalling 550 pages analysed. The event also marked the launch of TIC Kids Online Brazil 2025, a publication on internet use by children and adolescents aged 9 to 17 in Brazil.
