Question on what Underwriters use as far as credit scoring systems

[Breakthecycle2]

I was ALWAYS under the impression that when it came to credit, everyone uses FICO, however, we received our loan papers from Wells Fargo. In their documentation at the end, it explained why the our credit score wasn't perfect. My fiancee's EX is her highest at 747. The paperwork said they use a scoring system from 350-950. What are they using? Any idea?

Sounds like they're using Vantage.
