Photo ID, a bank check, or a face scan: how an under-16 social media ban might be enforced

What happened

On 29 October 2026, the communications regulator Ofcom published an assessment of how age checks could work for 16-year-olds. The background is a planned UK ban that would stop under-16s using some of the largest social media platforms. Reporting on the plan points to it coming into force in 2027, and Ofcom's work is designed to inform the government and Parliament before the detail is settled. Ofcom's job here was narrow but important. It looked at which methods of checking someone's age are reliable enough to tell whether a person is 16 or over. It identified four it considers capable of being highly effective: - Photo ID matching, where you show an identity document and a selfie is compared against it. - Digital ID services, where you verify a photo ID once with a provider, then use that verified status again without showing the document each time. - Banking-based checks, where a bank confirms you meet an age threshold without handing over your full details. - Facial age estimation, where software estimates your age from an image of your face. Ofcom was also candid about limits. It acknowledged that facial age estimation can be out by several years around the age of 16, and recommended extra checks where the software cannot be confident. It suggested a 'Challenge 25' style approach for ID checks, the same principle used in shops selling alcohol. It also said plainly that the 'risk of circumvention cannot be entirely eliminated'.

Why this matters

This is the point where a policy stops being an idea and becomes something that touches everyone's phone. An age limit sounds simple. Enforcing it is not. To stop under-16s using a platform, you have to work out the age of every user, including the adults. That is the part people tend not to think about until it arrives. So a rule aimed at children ends up as a check applied to the whole population. That is why the privacy argument is loud. The civil liberties group Big Brother Watch has criticised the proposal, describing it as a national ID system and warning that it could normalise handing sensitive personal information to private technology companies. There is also a practical inclusion problem. Estimates cited in coverage of Ofcom's work suggest around 94% of UK residents aged 16 or 17 have photo ID. That leaves roughly 150,000 young people in that age group who do not. Any system built around documents has to have an answer for them. And there is the simple question of whether it will work. Ofcom's own wording, that circumvention cannot be entirely eliminated, is a regulator saying out loud that determined teenagers will find a way round some of this.

What the evidence actually says

A few distinctions are worth holding on to, because coverage of this topic often blurs them. First, Ofcom has not banned anything, and nothing changed on 29 October. Ofcom assessed methods. The ban itself requires government and Parliament to decide the detail, and reporting puts it in 2027. Second, 'highly effective' is a technical judgement about whether a method can reliably sort people either side of an age threshold. It is not a judgement about whether the policy is a good idea, whether it will improve children's wellbeing, or whether it is proportionate. Those are different questions, and Ofcom was not answering them here. Third, the four methods are not equally intrusive and not equally available. A banking check reveals less than uploading a passport. A digital ID service means verifying once rather than repeatedly. Facial age estimation requires no document at all, but is the least precise, which is exactly why Ofcom paired it with a recommendation for backup checks. Fourth, some reported figures come from secondary coverage rather than Ofcom's own document, including the 94% photo ID estimate and the figure of around 150,000 young people without it. They are useful for scale, but they are not regulator-published statistics. The honest summary is that Ofcom has described a toolbox and been upfront about its gaps, rather than promising that age checking is solved.

Practical advice

If you are a parent, do not wait for the law. Whatever happens in 2027, the useful conversations with your child are the ones about what they see, who contacts them, and what they do when something upsets them. A legal age limit is a floor, not a plan. Check the parental controls and privacy settings on the apps your child already uses. They change regularly, so it is worth a look every few months rather than once. If you are asked to verify your age online, pause and look at who is asking and what they want. A reputable check should tell you what data it collects and how long it keeps it. Be wary of sites asking you to upload a passport image with no explanation. Be alert to scams. Any big, well-publicised change to online rules brings a wave of fake 'verify your account now' messages. Official checks happen inside the app or on the platform's own site, not through a link in a text or an email. If you do not have photo ID and may need to prove your age online in future, it is worth knowing that banking-based checks and facial estimation are among the options being considered, so a passport is not the only possible route.

What to know

Ofcom published an assessment on 29 October 2026 identifying four age-check methods it considers capable of being highly effective at determining whether someone is 16 or over: photo ID matching, digital ID services, banking-based checks and facial age estimation. This informs a planned UK ban on under-16s using some major social media platforms, which reporting places in 2027. Nothing has changed yet, and the final rules are for government and Parliament. Ofcom was open about the limits. Facial age estimation can be inaccurate by several years around age 16, so it recommended additional checks where confidence is low, along with a Challenge 25 style approach. It also said the risk of people getting round the system cannot be entirely eliminated. Critics, including Big Brother Watch, argue the approach amounts to a national ID system and risks normalising the sharing of sensitive data with private companies. Around 150,000 UK 16 and 17-year-olds are estimated to have no photo ID. For parents, the practical work is unchanged and does not depend on legislation: know what your child uses, check the settings, and keep the conversation open.
