Most people know there are three national consumer reporting agencies - Trans Union, Equifax and Experian. However, if you are a resident of Indiana, then your "Equifax" credit report is actually a report compiled from a credit file owned by a company called CSC Credit Services.  CSC owns, manages and controls the file and all information within that file but stores the file on Equifax's database and reports the file through the Equifax reporting system.  If you discover inaccuracies on a credit report prepared by Equifax and you reside in Indiana, you should dispute those inaccuracies directly with CSC which you can do by clicking the following link: CSC Credit Report Disputes.  Note, CSC owns credit files for residents in fifteen (15) mid-western and central states.
