In all 3 cases, the background checks were done by third party companies. HR receives a report from them that has text like "Employer 1 - Dates Verified, Position Title Verified." I also had "Employer X, called twice on number provided by applicant and left voice mails. No response from employer. W2s were provided." There's no reason for me to give my SSN to a third party. I typically provided my SSN to HR as part of the onboarding process after the background check was completed and my offer was finalized.
