Re: I need Experian's dispute phone number with a credit report number. yes, I noticed that too. i called yesterday using a number they provided me online. First attempt to dispute online, then they will give you a number if it can't be disputed online. I don't remember off the top of my head what it is, but you can't find it without attempting to dispute first.
