Tracking your credit score is a good way to know if youâ€re likely to qualify for credit or not. Itâ€s also an excellent way to see when youâ€re effectively getting ahead with your credit-building efforts. The three major credit bureaus in the US are Experian, Equifax, and Transunion. You donâ€t have to approach each bureau separately for a report. Instead, you can claim your free weekly credit reports from the top bureaus through the Annual Credit Report on their website.
