Why did I get "Please submit Tax ID information for your PayPal account"? Normal?

I just tried upgrading to a PP Business account. Upon entering the LLC EIN number, it took me to a page where PP requires to confirm my identity, which is stealth so no point...
It says the following:

"This information is required to verify your identity. This helps us to keep the PayPal community safe as well as meet government regulations.

SSN: (last 4 digits)
Date of birth:

The Patriot Act requires all financial institutions to ask for your Social Security number and confirm your identity to help prevent money laundering."

So it asks for the last 4 of the SSN of the Stealth name which of course I do not have. Does anyone know how to proceed here? Thanks!
