FICO score versions
The multiple versions of FICO scoring models used by different lenders — FICO 8 is most common but mortgage lenders use older versions.
Example
“Her FICO 8 score was 740 but the mortgage lender used FICO 5 which scored her at 718.”
Memory Tip
VERSIONS DIFFER — the score you see may not match what lenders pull. Multiple models exist.
Why It Matters
Understanding FICO score versions matters because different lenders use different models, which means your credit score can vary significantly depending on who is checking it. Knowing which version a lender uses helps you understand why your score might be different across various credit inquiries and how to better manage your creditworthiness.
Common Misconception
Many people assume they have just one credit score that every lender sees, but in reality there are multiple FICO versions and industry-specific models that produce different numbers. This is why checking your score through one service might show a different number than what a lender sees when you apply for credit.
In Practice
When you apply for a mortgage, the lender typically uses FICO 2, 4, or 5 rather than the consumer-facing FICO 8. For example, your FICO 8 score might be 720 from a credit monitoring app, but the mortgage lender checking FICO 4 could see a score of 705, which might affect your interest rate or approval odds.
Etymology
