Hi. If you mean Author ID Check you can find all the info you need here:
Basically ID Check is this:
“An Author ID check confirms the identities of our authors, requiring photo ID documents and a photo (selfie) of the account owner. This provides a trusted environment for our customers and authors to conduct business, and maintain the success of our community.”
And you can do the whole process with your smartphone, I did it this way, it’s really easy.
Hope this helps
