Not SSN it just means it is linked to your bank accounts
Adds a bit of security but not much
I'm sorry for the off topic but I can't even add from my own bank but all I know it's bank verified but tells me that I have to send them info like the one i mentioned.
What is the problem?
Aug 5, 2012: As of April, 2012, new Federal Regulations require Money Service Businesses, such as PayPal, to verify the identity of a customer before we can provide various services or product offerings. As a result, PayPal must ensure we have collected and verified important data such as customer name, address, date of birth, and national tax ID or social security number. Because we were not able to fully confirm your identity based on your current account information, we need to request additional supporting documentation from you.
