How the under-16 age checks will work
The ban only works if platforms can tell who's under 16. Ofcom reports by the end of October on which methods qualify. Here's each one in contention, and what it costs you in privacy.

Why age checks are coming
From spring 2027, platforms including Snapchat, TikTok, YouTube, Instagram, Facebook and X must keep under-16s off or face fines of up to 10% of worldwide revenue. A tick-box asking for a birthday doesn't survive contact with a twelve-year-old, and everyone involved knows it, so the rules will demand "highly effective" age assurance, the same standard the Online Safety Act already applies to adult content.
The UK has a head start here: age checks at 18 have been live on UK adult sites since July 2025, so the technology below isn't hypothetical. Millions of people have already used it.
What Ofcom is deciding now
Checking for 16 is harder than checking for 18 (the visual and data signals are weaker), so the government has asked Ofcom to run a rapid study on what counts as highly effective at that age,reporting by the end of October. Any qualifying method has to meet four tests: technically accurate, robust, reliable and fair.
The candidates are the ones already recognised for 18: facial age estimation, photo-ID matching, open banking, mobile-network operator checks, credit card checks, digital identity services and email-based age estimation. Expect platforms to offer several and let users pick.
Facial age estimation
A selfie, analysed to estimate age, then deleted: the method UK supermarkets already use at self-checkouts, from providers like Yoti. It needs no documents and no parent, which is why it's become the default first offer on adult sites since 2025.
Accuracy is the argument at 16. Estimation errs by a year or two either side, which matters enormously when the line is a sixteenth birthday rather than an eighteenth. Expect it paired with a buffer: look clearly adult and you pass; look anywhere near the line and you're asked for something stronger.
ID, banking and phone checks
The stronger tier works from records rather than faces. Photo-ID matching scans a passport or driving licence through a verification provider. Open banking asks your bank to confirm you're over the threshold without sharing anything else. Mobile-network checks use the age status already attached to your phone contract; credit card checks lean on cards being adult-only products.
Most of these prove adulthood better than they prove being 16. A 15-year-old has no credit card or driving licence, but neither do plenty of 16-year-olds. That's the awkward gap Ofcom's study has to resolve, and why the eventual mix may look different from the 18+ regime.
The privacy trade-offs
The pattern to watch is where the proof lives. Done well, verification happens at a third-party provider and the platform only learns "over 16". TikTok never sees your name or your passport number. Done badly, sensitive documents pool wherever the checks happen. Retention is the open question that matters most: how long providers can keep the selfie or the scan, and what audit trail platforms must hold. The autumn report and the regulations that follow will set those rules, and we'll report what they say.
Nothing, yet. If your children's devices already use family accounts with real birthdays, you're as prepared as anyone can currently be. The worst preparation is a family iPad account claiming everyone was born in 1980. Fix that at your leisure before 2027.
Common questions
Will I have to upload my ID to keep using social media?
No. The government has said explicitly that age checks will not require handing over government-issued ID, and that no digital ID will be needed to use social media. Expect softer signals first (facial age estimation, account history), with document checks as one voluntary option among several rather than a requirement.
What happens if my child fails an age check wrongly, or passes one they shouldn’t?
Both happen at the margins; estimation is least reliable exactly around the age it needs to judge. What appeal routes platforms must offer is one of the open questions for the regulations due before Christmas. We’ll update this page when they’re published.
Do age checks apply to games and YouTube?
YouTube is in scope of the ban, so it will need to check for 16. YouTube Kids is exempt. Games aren’t covered by the account ban, but planned restrictions on contact from strangers extend to gaming platforms, which implies some age signal there too.
