Although Experian is the largest credit bureau in the U.S., TransUnion and Equifax are widely considered to be just as accurate and important. When it comes to credit scores, however, there is a clear winner: FICO® Score is used in 90% of lending decisions.
Is Equifax or TransUnion accurate?
Neither score is more or less accurate than the other; they're only being calculated from slightly differing sources. Your Equifax credit score is more likely to appear lower than your TransUnion one because of the reporting differences, but a fair score from TransUnion is typically fair across the board.
Which credit score is most important Equifax or TransUnion?
Equifax: Which is most accurate? No credit score from any one of the credit bureaus is more valuable or more accurate than another. It's possible that a lender may gravitate toward one score over another, but that doesn't necessarily mean that score is better.
