My FICO with Discover went down for three mounts from 770 to 723. Is Discover using a different FICO version? Now my Walmart and Barclay’s score went from 770 to 765 on both for the same time line. When I applied with Avant for a loan they said my score was 723 also. I want to get a Barclay’s card but don’t know what score I should believe. Has anyone else had this happen to?
