Can anyone confirm this information is actually shared? Last month, I went through a background check for a new position which used The Worknumber. Not all data was present & correct (a previous employer was acquired and that goofed some data). When I was asked by The Worknumber to correct it, they wanted a W2 and said (direct quote from web form):

"Please redact or conceal any compensation related information on any documentation you submit. It is not permissible (either by law and/or company policy) for <new company> to view such information as part of your background check."

So can the new company actually get access to the compensation information? Is that perhaps a state law?
