Why is this service asking me to verify my age?
Almost always because of the Online Safety Act 2023. Ofcom's children's safety duties require services likely to be accessed by under-18s, and any service carrying pornography, to use "highly effective age assurance" for the content they gate. Services began switching checks on through 2025 and 2026, which is why a site you have used for years can ask for a photo ID one day without warning.
Short answer. Of the 23 services tracked here, 7 gate everything, 13 gate some content or features, and 3 had no age check when we last looked. 5 of the checks in this index were first observed in 2026, and the dates we hold run from 2025 to 6 May 2026. 20 services publish what happens if you decline.
When each check appeared
Newest first, because the question is usually prompted by a check that has just turned up. The date is when the check was first observed for UK users, with the source on each service page.

Why it arrived all at once
Ofcom's duties came with dated deadlines rather than a single switch-on, so services clustered their changes around them. The timeline lists every dated step, including the ones still ahead, each with its source. Where Ofcom or the ICO has opened an investigation or issued a fine, it is on the enforcement page with the amount and the date.
Why the check differs from app to app
The Act sets the duty, not the method. Each service chooses how to meet it — a selfie estimate, a photo ID, a credit card, a mobile-network check, an emailed digital ID, or an inference drawn from account signals — and most use more than one. What each method collects, and what Ofcom has said about it, is on the methods pages.
If you would rather not
The "if you decline" column above is the service's own published statement of what you lose, quoted on its service page with a source. For most partly-gated services it means the gated content stays hidden and the rest keeps working. This site does not carry advice about avoiding checks, and it never will: it records what the services and regulators publish, nothing more.
