“Full Social Security Number” is a field under Company Information, next to SSN/ITIN Last 4. It appears only when our payment processor, Stripe, needs the full number to verify the person who represents your company, and it must be filled in before payouts can be sent.
For when Stripe asks for the full number and why, see Why do I need to provide my full Social Security Number?
