Question: what is the difference between fico 2 and fico 8?
Answer: FICO 8 and 9 aren't the only versions in use. ... FICO 2, 4, and 5 are very similar. The main differences between the three is that 2, 4,and 5 use data from Experian, TransUnion, and Equifax respectively. Mortgage lenders pull one of each and compile the reports in a document called a Residential Mortgage Credit Report.
