15: France draws the line, and the rest of Europe is taking notes

Fifteen. That is the new floor. On Tuesday, July 21, 2026, the French parliament approved a law barring anyone under fifteen from opening a social media account, making France the first country in the European Union to write that line into statute ^245671011.

The vote was lopsided in the lower house. The National Assembly passed the bill 279 to 81, with both chambers ultimately backing the measure ⁷⁸. That margin does the work of explaining why this is the first such law in the bloc rather than the fifth: in capitals where the politics of childhood and the internet has split coalitions, the bill either dies in committee or never reaches a floor vote. In Paris, it cleared.

Under the new statute, social media platforms operating in France will be required to verify users' ages, with the practical effect that anyone in France who wants to scroll a feed will have to prove how old they are before the algorithm opens ³¹¹. The BBC reports that under-15s will be barred from the platforms beginning in January 2027 ³. One outlet notes President Emmanuel Macron wanted the ban in force before the next school year began ⁵.

That detail matters because the law's mechanics are still being negotiated behind it. Reporting describes France as on the cusp of finalizing the implementation, with age verification identified as the load-bearing piece ¹¹. What the publicly available reporting does not confirm are several specifics that have circulated alongside the bill: a September 2026 rollout for blocking new accounts, a January 2027 deadline for removing existing under-15 accounts, the named platforms the measure targets, or any companion ban on phones in high schools. Those claims appear in commentary around the law; the parliamentary record, as reported here, points to January 2027 as the operative date and to age verification as the central obligation ³¹¹.

This is not a bill that wandered out of committee. It is the centerpiece of Macron's second-term domestic tech agenda, a reform he championed publicly and tied to his own presidency ³⁷⁹. The same day the vote landed, Macron visited a children's health centre in Paris, a stage-managed stop that signaled where he wants the legislation to land in the French memory ⁴.

Politico's framing is sharper than most: the ban cements a tech legacy Macron has spent years assembling, an argument that the second-term president's domestic reform identity is now inseparable from how France treats its children's screens ⁹. For a leader whose national agenda has thinned out elsewhere, the under-15 question offers a clear, child-shaped target with built-in political cover.

France did not invent this fight. It joined it late. Australia became the first country in the world to enact an under-16 social media ban late in 2025 ⁶. The United Kingdom announced its own restrictions in June 2026, one month before the French vote ⁶. Inside the EU, Greece, Slovenia and Sweden are all working through versions of similar restrictions, according to Euronews ¹⁰.

Put those dates on a single line and the picture shifts. What looks like a French first is, more accurately, the front edge of a European wave. Each capital is writing its own statute, with its own age threshold and its own verification regime, and each is watching the others to see which version survives contact with the apps. Paris is the test case in scale rather than in concept.

The political fight is mostly over. The engineering fight is just beginning. Age verification, applied to every social media user in France, is the mechanism that turns a parliamentary vote into a working rule, and it is also the place where civil liberties objections live ¹¹.

The IAPP's coverage flags this directly: the law requires platforms to determine a user's age, and France is described as on the cusp of finalizing the implementing arrangements ¹¹. The BBC frames the moment similarly, noting that the UK and the EU are still developing their own limits in parallel ³. What is missing from the publicly available reporting are two claims that have traveled with the bill: warnings from privacy campaigners that the verification systems could be invasive and easily evaded, and the threat from left-wing lawmakers to refer the legislation to France's Constitutional Council on civil liberties grounds. Those points are circulating in commentary; they are not, on the basis of the sources gathered here, established as fact.

The reason Greece, Slovenia, and Sweden are drafting their own versions rather than waiting for Brussels is the reason Paris just voted. The EU itself is moving toward limits, but slowly, and capitals with the political appetite have decided to move first ³¹¹. France has now provided them with a draft, a vote count, and a date to point to.

What it has not yet provided is a working age gate. The law that passed on July 21 is the easy half of the problem: declaring that children under fifteen should not be on these platforms is the part every democracy can agree on in a poll. Building a verification system that respects a seventeen-year-old's privacy, defeats a thirteen-year-old's VPN, and survives contact with a global app economy is the hard half, and it is still ahead ³¹¹. France has drawn the line. Whether it can hold it is the story the next six months will tell.
