I see where I can check the status of a dispute online with Experian but where can I do this with Trans Union? I don't see a link on their site.
Their website does not have that capability. You must obtain another report to check for any changes. It sucks, I know...
Call them for a status. I do it all the time and 99% of the time, they are real nice and tell me what's going on. Just explain that you don't remember exactly when you initiated the dispute and they'll usually help you out.
Call 1 (800) 916-8800 with your FIN (File ID #) TU doesn't provide online status. When you get the results in the mail, look on the back for your updated score.
