How do I get a tax ID?

So, I'm streaming on Twitch regularly and am now applying for my Twitch Affiliate. Only I have to specify a tax ID there.
I'm 15 years old and do not earn any money through a job I could tax. Where can I find this tax ID then?
Would I have to call the BZSt for it or what does it look like.

Call your tax office. They say and / or send you.

That should have your responsible tax office for you.

Do I have to be 18 or something?

Federal Central Tax Office.
