The first step to interpreting a score is to identify the source of the credit score and its use. There are numerous scores based on various scoring models sold to lenders and other users. The most common was created by FICO and is called FICO score. FICO is a publicly traded corporation (under the ticker symbol FICO) that created the best-known and most widely used credit score model in the United States. FICO produces scoring models which are installed at and distributed by the three largest national credit repositories in the U.S (TransUnion, Equifax and Experian) and the two national credit repositories in Canada (TransUnion Canada and Equifax Canada). FICO controls the vast majority of the credit score market in the United States and Canada although there are several other competing players that collectively share a very small percentage of the market.
