Why Do I Have Different Credit Scores? All Your Scores Explained

You Have More Than One Score — By Design

The term "credit score" does not refer to a single number. FICO alone has produced over 50 scoring models. VantageScore has four versions. And there are industry-specific models for auto lenders, mortgage lenders, and credit card issuers. Every one of these models can — and usually does — produce a different number for the same person.

Why Your Scores Differ

Reason 1: Different Scoring Models

Score / Model	Used By	Range	Where You See It
FICO Score 8	Most credit card issuers, personal lenders	300–850	Many bank apps, Experian free tier
FICO Score 9	Newer lenders; ignores paid collections	300–850	Some card issuers
FICO Score 2 / 4 / 5	Mortgage lenders (Fannie/Freddie requirement)	300–850	Only via mortgage credit pull
FICO Auto Score 8	Auto lenders	250–900	Rarely seen by consumers
VantageScore 3.0	Credit Karma, Credit Sesame, many free services	300–850	Free credit monitoring services
VantageScore 4.0	Newer lenders; bureau-promoted model	300–850	Experian, TransUnion apps

Reason 2: Different Bureaus Have Different Data

Equifax, Experian, and TransUnion each run independent databases. Lenders are not required to report to all three — many report to only one or two. As a result:

An account may appear on one bureau but not another
A recent payment may have been reported to two bureaus but not the third
A hard inquiry only appears at the bureau the lender pulled
An error on one report may not exist on the others

A spread of 20–40 points across the three bureaus is completely normal. More than 60 points suggests an error or a significant data difference worth investigating.

Reason 3: Different Calculation Dates

Scores are calculated at the moment a lender or service requests them. If one service updated your score last Tuesday and another updates it today, they may reflect different underlying data — a payment processed, a balance updated, an inquiry reported.

What Score Does My Mortgage Lender Use?

Mortgage lenders must use specific FICO models as required by Fannie Mae and Freddie Mac: FICO Score 2 (from Equifax), FICO Score 4 (from TransUnion), and FICO Score 5 (from Experian). They pull all three, then use the middle score. This is why your mortgage score often differs significantly from the score you see on your credit card app.

What Score Does My Auto Lender Use?

Auto lenders typically use FICO Auto Scores, which are industry-specific variants that give more weight to how you have handled previous auto loans. These can produce scores that are notably different from your general FICO Score 8.

The Bottom Line: Track Trends, Not Exact Numbers

Because scores vary by model and bureau, focus on the direction of movement rather than hitting a specific number on a free service. A rising trend across multiple services and bureaus is a reliable signal your credit health is improving. When applying for a specific product, ask the lender which score model they use — some will tell you.
