I'm curious about the Date of Last Activity which seems to be a very important date in one's credit file. I retrieved all three of my reports online and only one report, Equifax has the actual wording: Last Activity. One debt that appears on all three reports are as follows: Equifax lists a Last Activity Date of 11/94. Experian only lists: Date Opened, Reported Since, Date of Status, and Last Reported. All of which are listed as 11/99. The TU version regarding the same debt says Balance Date 7/1/99. Do the copies that one receives through the mail contain more info than the online versions?
