Tax information - Tax ID Number - Birth identification number?

Hey guys I wanted to ask if anyone who was filling out tax ID number used their birth identification number.

I found this pdf: https://www.oecd.org/tax/automatic-exchange/crs-implementation-and-assistance/tax-identification-numbers/Slovak-Republic-TIN.pdf

Where it says and I quote “If natural person does not have a TIN then a unique birth identification number is used for tax purposes.”

And it shows where on your ID you can find it.

Does that mean I can use that here as my Tax ID Number? Or is that something else.

I’d appreciate any help. Thanks!
