France Just Banned Social Media for Kids Under 15, and the Fight Over Anonymity Is Only Getting Started

France becomes the first EU nation to bar under 15s from social platforms, and critics say the real cost is the end of anonymous browsing.\

Paris lawmakers spent Monday night into Tuesday morning arguing over a bill that has been circling French politics since late 2025, and by Tuesday afternoon it had cleared both chambers of parliament. The National Assembly passed the measure 279 to 81, a lopsided margin that belies how contentious the underlying question has become across Europe: how young is too young to be handed a phone loaded with algorithmic feeds built for adults.

The bill bars anyone under 15 from opening a new social media account starting September 1, timed to the start of the school year. Existing underage accounts get a longer runway, with platforms required to deactivate them by the end of the year. A companion measure bans phone use inside French high schools, extending a policy already in place at primary and middle schools since 2018.

President Emmanuel Macron has treated the bill as a signature project of his second term, and he said as much on X shortly after the vote, calling it a major step for protecting French children and teenagers. He has pushed for enforcement to begin by September regardless of how quickly the technical details get worked out, a timeline that has already drawn skepticism from the people who will have to build the actual verification systems.

Enforcement falls to Arcom, the French regulator that already oversees broadcasting and online platforms after absorbing the old CSA and Hadopi agencies in 2022. Arcom will decide which platforms count as social media under the law and how compliance gets checked, and it is expected to apply the rule to every major network operating in France.

Earlier drafts went further than what actually passed. Proposals to ban influencer advertising aimed at children and to force social platforms to display warning labels reading “dangerous products for children under 15” were both stripped from the final text. What survived is narrower: an age floor, a school phone ban, and an enforcement mandate handed to a regulator that has not yet said exactly how age checks will work in practice.

That gap matters. Arcom has pointed to its own research showing French teenagers aged 12 to 17 spend an average of one hour and 21 minutes a day on TikTok, and the regulator has said the platform’s recommendation system tends to surface the most extreme content available, feeding teenagers a steady diet of material designed to provoke anxiety rather than inform. TikTok and other platforms have said they already restrict certain categories of content for younger users, though that has done little to slow the legislative push.

war

Not every lawmaker signed on. The left wing party La France Insoumise voted against the bill, and its objection wasn’t really about whether social media harms kids. It was about what enforcing an age limit requires everyone else to give up.

Their argument, in short: any system capable of reliably confirming someone is over 15 has to be capable of confirming who that person actually is, at least at the moment they sign up. That effectively ends the ability to create an account without identifying yourself in some form, a tradeoff that stretches well beyond the population the law is meant to protect. Party lawmakers also raised doubts about either the bill would survive constitutional review and whether it could realistically be enforced against a platform with headquarters outside France.

That’s the same fault line running through age verification fights in the United States, where similar arguments have stalled or reshaped state level laws aimed at pornography sites and, increasingly, social platforms. The mechanics are identical no matter the country: age gates require identity signals, and identity signals are the opposite of anonymous browsing.

Ines Legendre, a legal advisor at the child online safety group e-Enfance, told reporters the law won’t flip a switch on implementation day. Existing accounts belonging to under 15s still have to be identified somehow, and someone has to decide how those accounts get suspended once flagged. New account verification is a separate technical problem on its own timeline. None of that is settled yet.

tool

This is the part nobody has fully answered. The most direct method, uploading a passport or driver’s license, works but creates an obvious workaround: a younger teen borrowing an older sibling’s or parent’s ID. It also means every user, not just the ones near the age line, hands over a scan of a government document just to make an account, which is precisely the kind of data collection that makes privacy advocates uneasy.

Selfie based age estimation and behavioral analysis are the other options on the table, and both lean on AI models trained to guess age from a photo or usage pattern. They’re faster and less invasive than an ID scan, but they’re also less accurate, and mistakes cut both ways: a 14 year old gets waved through, or a 19 year old gets locked out of an account they’re legally entitled to hold. Layer on GDPR’s data protection requirements and the compliance picture gets complicated fast for any platform trying to operate across the EU with one system.

France’s digital affairs minister, Anne Le Hénanff, has floated a further step that goes beyond the bill’s original scope: restrictions on VPN use, aimed specifically at teenagers routing around age checks by masking their location. She has been clear the government isn’t pursuing a blanket VPN ban, only a way to close the most obvious loophole, but the comment alone was enough to worry digital rights groups who see it as the natural next request once an age gate is in place. Once a government builds infrastructure to check ages at the door, extending that infrastructure to check other things gets easier, not harder.

Australia’s under 16 ban, which took effect in December, ran into exactly this problem at scale. Two separate studies published earlier this year found a meaningful share of Australian teenagers kept using restricted platforms anyway, some through weak age gates and some through workarounds that had nothing to do with technical sophistication. Roblox’s rollout of its own age verification system produced a similar string of early complaints. France’s regulators have not said much publicly about how they intend to avoid the same outcome.

debate

Public opinion has been on the side of restriction for a while now. A Harris Interactive survey from 2024 found 73 percent of the French public supported an age floor for social media, and the health data since then has only added weight to that view. France’s national health watchdog reported in December that roughly one in two teenagers spends between two and five hours a day on a smartphone, and that about 90 percent of children aged 12 to 17 use a smartphone daily to get online, with 58 percent of them specifically using it for social networking.

Behind the statistics are families with direct grievances. Several have filed suit against TikTok over teenage suicides they argue are linked to the platform’s content, part of a wider pattern of legal action against social platforms playing out in multiple countries at once. Gaelle Berbonde, a 52 year old parent from the Paris region who has campaigned for the bill, told reporters after the vote that families had no other real option left to counter platforms of that scale on their own.

The stabbing at a school in eastern France in April also shaped the political mood. Macron pointed to the attack as part of his case for EU wide regulation, arguing that social media’s role in youth violence extends beyond any one platform or country and needs a coordinated response rather than a patchwork of national rules.

stance

France’s vote makes it the first EU country to pass a blanket social media age limit, but it’s following a path other governments have already tested. Australia enacted the first version of this kind of ban for under 16s in December, restricting access to platforms including Facebook, Snapchat, TikTok, and YouTube. Indonesia has a comparable rule already in place. The United Kingdom has announced its own restrictions, expected to take effect next year, and Spain, Greece, and Denmark are each working through their own minimum age proposals.

The European Commission weighed in the same day the French bill passed, acknowledging France’s right to set the rule domestically while noting that enforcement ultimately has to fit within EU law, a reminder that a national ban and a workable EU wide framework are not automatically the same thing. Macron has said he wants to push for that broader EU level standard, following a call from the European Parliament in November urging member states to set minimum ages of their own to address rising adolescent mental health concerns.

extend

The bill still has to clear France’s Constitutional Council, the body responsible for confirming that any new law fits within the country’s constitution before it can take effect. That review is where the anonymity argument raised by opposition lawmakers gets its real test, since a finding that the bill infringes on protected rights could send parts of it back for revision. The council has ruled against digital regulation before on narrower grounds, so nobody in Paris is treating this stage as a formality, even with the vote margin as lopsided as it was.

Assuming it clears that hurdle, the September 1 start date applies to new accounts first, with existing underage accounts facing removal by the end of the year. Arcom still has to publish the technical specifics of how platforms are expected to verify age, and that detail, more than the vote itself, is what will determine whether the law changes daily behavior or becomes another rule that’s easy to route around. Gabriel Attal, who leads Macron’s Renaissance party in the lower house, has said he hopes enforcement mechanisms come together quickly enough to hit the September deadline, though the age verification questions raised during debate remain open.

There’s also the matter of what counts as a covered platform in the first place. The bill’s language targets social networks and embedded social networking features, a definition broad enough to sweep in messaging apps with public facing feed elements and gaming platforms with in game chat and profile systems, not just the obvious targets like Instagram or Snapchat. Arcom will have to draw that line somewhere, and wherever it lands will shape which companies spend the rest of the year building compliance systems and which quietly argue they fall outside the law’s scope.

Platforms themselves have been mostly quiet in public beyond noting existing safety features already aimed at younger users. That’s a familiar posture from past European regulatory fights, where companies tend to wait until enforcement details are finalized before committing engineering resources to a specific compliance approach. It also means the September deadline is as much a target for the platforms as it is for Arcom, and slippage on either side would not be surprising given how much of the verification method remains undecided months out from the deadline.

For parents and teenagers alike, the practical experience of the law will likely arrive in stages rather than all at once. New signups face the tightest scrutiny starting in September, while existing accounts get a longer window that stretches into the new year, meaning the law’s actual bite on daily habits won’t be fully visible until sometime after the school year is already underway. Whether that staggered rollout closes the gap Australia is still working through, or opens the same kind of workaround problem at a different pace, is the open question hanging over the months ahead.
