Britain's communications regulator has identified four methods for verifying that internet users aren't children as the country prepares to enforce its proposed ban on social media for people under 16. Ofcom released the shortlist today, narrowing down from seven techniques initially outlined when the Online Safety Act took effect last year. While some adults may avoid proving their age through platform inferences based on past activity, the regulator confirmed that "many" will likely face the same verification process as younger users.

The four approved methods include photo-ID matching, which checks information displayed on identity documents and compares the photo against a live image captured during verification; banking checks, which rely on identity documents provided when opening accounts that an estimated 90 percent of 16-17-year-olds in the UK possess; digital ID services from third parties that analyze a person's photo once and allow age verification across multiple platforms; and facial age estimation, which Ofcom acknowledged isn't reliable enough to use alone due to margins of error spanning several years. The regulator estimates that around 94 percent of 16-17-year-olds in the UK hold some form of photo ID, such as a passport, driving licence, or an ID card certified by the Proof of Age Standards Scheme, leaving approximately 150,000 without any. Three additional methods reserved for those 18 and older include credit card checks, mobile network operator checks, and email checks that make educated guesses about age based on other registered services.

According to Big Brother Watch Director Silkie Carlo, "This plan for a government 'social media ban' is a national ID system by the back door." She added that both the government and Ofcom have admitted children will circumvent the ban, meaning "the real effect will be normalizing adults and children alike to handing over their passports just to get online." The regulator itself conceded that "the risk of circumvention cannot be entirely eliminated," noting that some children will devise ways to bypass age checks regardless of how thoroughly they're implemented. In May, nearly a year after the Online Safety Act's age verification requirements launched, researchers discovered that existing age checks proved largely ineffective at keeping under-18s away from adult content online, with some reporting they beat checks using only a drawn-on moustache.

Ofcom cited Australia's experience with an under-16 social media ban introduced in December 2025, where a large proportion of children have found ways to evade these checks. The UK government intends to adopt but learn lessons from Australia's rollout, committing to more robust measures that promote the ban's aims. The regulator identified potential mitigations against circumvention, including making it easier for users to report suspected underage social media users and deploying age inference models. England's Children's Commissioner, Dame Rachel de Souza, said recently that the Online Safety Act "has made absolutely no difference" to children's ability to access potentially harmful online content. The UK government is expected to outline the first set of regulations related to the under-16 social media ban by year's end, and Ofcom is developing draft guidance for platforms, with enforcement ready to begin in 2027 and monitoring of circumvention methods planned for the first 12 months. Privacy advocates warn that hundreds of thousands without ID, who tend to be poorer people, and many more unwilling to hand passports to foreign tech companies will be locked out of large portions of the internet. The tension between child safety goals and privacy concerns will intensify as platforms navigate the gap between regulatory compliance and user resistance to identity disclosure.
