why dose epic need my full ssn

i have been trying to set up my hyperwalet to publish the games that i have developed. But i think that it is very unnecessary that epic requires my full ssn when they could by using more safe ways to verify my age. Such as a state drivers lisenes or passport. Epic please reach out to me.

Don’t quote me on this, but as it is tax related I guess it has something to do with the cashout / payment process rather than just age verification.
