There are three major credit bureaus (Experian, Equifax, and TransUnion), and each can hold slightly different information about you depending on which lenders report to them. Layer on top of that multiple scoring models — FICO alone has over a dozen versions — and it's normal to have 20+ technically valid credit scores at any given moment.
Why the differences exist
A lender might report your auto loan to two bureaus but not the third. A scoring model built for mortgage lending weighs factors differently than one built for credit cards. None of this means one score is 'wrong' — they're each accurate answers to slightly different questions.
Track trend, not the exact number
Instead of fixating on matching the score a specific lender will use, watch whether your free score is trending up or down over time. The direction matters more than the precise figure on any one app.
Which score actually matters for your application
- Mortgage lenders often use older FICO versions specific to mortgage underwriting.
- Auto lenders frequently use an auto-industry-specific FICO score.
- Credit card issuers commonly use FICO 8 or VantageScore 3.0/4.0.
- The free score on your banking app is usually for informational tracking, not the exact number a lender will pull.
