Credit scores are often referred to simply as FICO scores. FICO (Fair Isaac Corporation) is the most commonly used scoring model for lending and credit decisions in the U.S., though other scoring modules do exist FICO scores range from 300 to 850 where higher is better. Consumers have a FICO score from each of the three credit reporting agencies – Equifax, Experian, and Transunion. Other credit scoring models do exist, so not all credit scores available for purchase online are FICO scores.
