It's not required in my country and I get the checks. This has nothing to do with legislation.

I can't confirm without knowing what country you live in. I understand essentially the whole EU requires this, and the US is one example where the checks aren't required.

How would you confirm though? So far I'm seeing a lot of rumors but no one seems have produced any actual legislation that I can see anyway.

This is covered by the Audiovisual Media Services Directive 2018/1808. EU member states were supposed to transpose this into national legislation by 19 September 2020, but not all have.

When you say "get the checks" do you mean YouTube is asking for a copy of your ID or that it's giving you the regular age gate check?

Please say which country you're referring to when you say "in my country" on the internet. It allows others to contextualize and verify otherwise useless information.

Do you get the check that you need any account, or the check that you specifically need an account with ID verification?
