France Banned Social Media for Under-15s. Nobody Wrote Down How.

On September 1, France made it illegal for anyone under 15 to open a social media account.

The law does not say how a platform is supposed to know that you are 15.

What is actually in force

The French parliament passed the bill on July 21. Al Jazeera and France 24 both covered the vote. Since September 1, no new accounts for under-15s on TikTok, Instagram, Facebook, Snapchat or X. From January 2027, existing under-15 accounts have to be age-verified or closed.

There is no parental consent exception, which is the loophole critics said would hollow out Australia's version. Online encyclopedias, educational and scientific directories, and open-source development platforms are exempt.

So the rule is clear and the scope is clear. The mechanism is the missing part.

The hole in the middle

The statute never specifies a verification method. Not ID checks, not face estimation, not anything. That decision got handed to CNIL, the French privacy regulator, which now has to approve whatever tools the platforms propose. TechTimes flagged this at the time and most of the wire coverage skipped past it.

The deadline arrived before the method did.

We want to be careful here, because the easy version of this post is a sneer, and a sneer would be wrong. This is a genuinely hard problem. Every workable age check trades a child's privacy for a child's protection. To prove that a user is not 14, you have to collect something from every user, including the adults. There is no age gate that only touches children.

France's parliament looked at that trade, passed the law anyway, and left the trade itself to a regulator. You can call that cowardice or you can call it division of labour. Either way it was a decision, not an oversight, and it is worth saying out loud rather than pretending the law is simply unfinished. Platforms now have to build something and get it blessed, and the same fight is queued up in Chile and Argentina, with age assurance going global through 2026.

The half of the law nobody covered

The same bill bans phones in secondary schools.

France has had a phone ban in primary and middle schools since 2018. This extends it to lycée, which means 15 to 18 year olds. PBS NewsHour mentioned it. Almost nobody led with it.

Think about which of these two changes a French teenager will actually notice. A 14-year-old who already has an Instagram account keeps it until 2027. A 16-year-old hands over their phone at the school door tomorrow morning, every morning, for the rest of their education. We have written about what happens when schools go phone-free, and the effects are not small.

The account ban got the headlines because you can argue about it on television. The school clause got a paragraph because it is boring and it works.

Four governments, one conclusion

Australia, the UK, France, with Chile and Argentina moving. Four governments have now looked at products engineered to be hard to put down and reached the same answer: an enforced default that the user cannot switch off.

That is not a coincidence, and it is not really a political finding. It is the same result the research on blockers keeps producing. When people choose their own limits, the limits mostly do not hold. When the limit is imposed and cannot be undone in the moment, it does. Legislators arrived at the mechanism from one direction and behavioural researchers arrived at it from the other. Worth noticing that every one of these laws draws its line at a birthday and exempts the adults who wrote it.

The takeaway

If you are waiting for a government to solve your relationship with your phone, France is a useful preview. The law that made the news is the one nobody knows how to enforce. The law that will change a real Tuesday is the one about a box by the classroom door.

Enforcement is not the exciting part. It is the only part.
