<prompt> Human: Why is there such a huge discrepancy between what different sources say for my credit score?On Credit Karma my TransUnion is 803, Equifax is 798. Then i look at my FICO score through WF and it is 666. Imo it shouldnt be low as ive never been late on bills and have several sources of credit. Anyone else seen this before or understand?  <response>: Credit Karma is NOT FICO, it is a VantageScore which is a different calculation altogether.The vast majority of lenders use FICO.
