I'm pretty sure you can still just add your EIN and it should still pass.
Is this a new account registration? they tend to ask for docs if you don't use the right VPN. Residential IP is a necessity btw. And if the info you gave them crossed with previously used account or simply they detected a cookie from other accounts.
This is what I have found to be most common now adays
this is using my real info, i havent had a paypal account under my name before if i did it was like 12 years ago too. i used few stealth accounts over the past 10 years. dont use VPN either i never used this internet service before when moving to my new location a year ago
