I'm sure everyone knows that you are entitled to, by law, one free credit report per year. What I did not know, is that you can request that free credit report online at https://www.annualcreditreport.com I was able to get both my Experian, and Equifax reports right away. Transunion says I already have an account with them and I have to call them to reset my password. I think they are just being difficult.
I highly recommend looking at all three, there was a vast difference between my equifax and experian reports in terms of former addresses. You can even dispute somethings online, though it seems very limited. I was able to dispute 2 incorrect former addresses but not the other 3.
