Ofcom Age Checks for the Under-16 Social Media Ban Will Reach Adults Too

Britain now has a shortlist for proving you are not fifteen. On 29 October 2026, Ofcom set out the Ofcom age checks for the under-16 social media ban: four methods the regulator calls highly effective for establishing whether a user is 16 or over. Photo ID matching, banking-based checks, digital ID services and facial age estimation made the list. The ban itself is due in March 2027, and the government is expected to decide which checks to require by the end of this year.

Information verified through 1 November 2026.

The four Ofcom age checks for the under-16 social media ban, and the three that failed the test

Each method leans on something a teenager is unlikely to fake cheaply. Photo ID matching checks a document such as a passport against a live image taken during the check. Banking checks use the date of birth a bank already holds — and banks asked for documents when the account was opened. Digital ID services verify a person once, then vouch for their age elsewhere. Facial age estimation reads a face and guesses.

Three familiar methods were cut. Credit card checks, mobile network checks and email-based checks can show that someone is over 18, but they cannot settle the narrower question of whether someone is over 16, which is the only question this ban asks. Ofcom also rejected parental consent as a model, citing evidence that some parents give a wrong age to help their children get round restrictions.

Facial estimation is the softest of the four. It carries a margin of error of a few years, right at the age where accuracy matters most, so Ofcom suggests a second method as back-up where the estimate is not confident — a version of the Challenge 25 habit in shops, where anyone who looks young gets asked for documents anyway.

Adults prove age for social media in the UK, too

Here is the part that widens the story beyond teenagers. A platform cannot check only the users it suspects. To keep under-16s out, it has to establish the age of people it cannot already place, and Ofcom concedes that many adults are likely to be asked to prove their age. Some adults with long-standing accounts may be passed on the platform’s existing information about them. Plenty won’t.

The gap falls hardest at the legal side of the line. Ofcom estimates about 150,000 16- and 17-year-olds have neither a passport nor a driving licence, the two documents adults reach for without thinking. Banking checks help because around 90 per cent of British 16- and 17-year-olds have a bank account, and proof-of-age cards offer another route. Still, the regulator’s own logic means some lawful users will need to obtain ID they never needed before, simply to keep accounts they are entitled to hold.

Civil liberties groups have not been quiet. Big Brother Watch director Silkie Carlo called the plan “a national ID system by the back door”, arguing that its real effect will be to normalise handing passports to platforms. Ofcom’s counter, in chief executive Dame Melanie Dawes’s words, is that “it can work if social media firms do highly effective age checks properly”, and that the checks can be delivered in ways that protect privacy and comply with data protection law. Both positions are now on the record. The regulations will decide which one the system resembles in practice.

Lessons from Australia’s under-16 ban

Britain is not going first, and Ofcom has read the field report. Australia’s ban has been in force since December 2025, and reports there say many under-16s can still get onto the platforms. Australia left more of the policing to the platforms themselves, and the UK says it intends to take a tougher approach than the Australian rollout, precisely because the first version leaked.

Ofcom is blunt that circumvention cannot be eliminated. Dawes compared it to alcohol law: motivated children will try to get round the rules, as some do with drink, and platforms will have to mitigate — easier reporting of suspected underage accounts, age inference models, and close monitoring of workarounds during the first year. The ban is expected to cover ten of the biggest platforms, including Instagram, TikTok and Snapchat.

Analysis: The honest tension sits in Ofcom’s own document. A check weak enough to leave adults alone will not stop a determined fourteen-year-old with an older sibling’s passport photograph. A check strong enough to stop her asks millions of adults to identify themselves to companies many of them distrust. Ofcom has chosen the strong end, and said so plainly. Whether ministers keep that choice when the regulations land by the end of the year is the decision to watch.
