It didn't go into detail about what items were disputed like the Trans Union letter did. In fact, while the Trans Union letter was several pages, the Experian was about a half page of text. Like the TU letter, it contained a blurb about credit repair agencies. I've gathered from messages here that Equifax doesn't send these confirmation letters, so I'm not expecting one. My TU investigation is due to finish on 5-18, and Experian is giving themselves 30 days starting 4-25.
