Why are Equfax/Eper/Trans Scores all different and lower then my FICO score?

[Anonymous]

My Fico score according to Equifax on its report is 620. But all 3 of my reports say, Exp 584 /  Equi 572 / Trans 572..? signed Confused but trying to make my score better...why aren't they all the same and why is my FICO better?  Thanks...NewBe

Please read the credit scoring 101 thread in my siggy. Also, keep in mind all three FICO scores use different scoring algorithms, thus the differences in scores sometimes.

Also, I forgot to mention, if there are any differences between what's being report on your three reports (which is quite common), there can be differences in scores. This includes the good, the bad and the ugly. Sometimes there can be big differences.
