Most lenders use some version of the FICO Score, but the specific version depends on what type of credit you’re applying for. A credit card issuer, an auto lender, and a mortgage company may each pull a different FICO model, and the score they see can differ by dozens of points from the number you check on a free monitoring app. Understanding which scores matter for which products helps you know where you actually stand before you apply.
FICO Score 8 Is the Most Widely Used
FICO Score 8 remains the most commonly used base credit score across the lending industry. It was introduced in 2009 and has become the default for many lenders who haven’t migrated to newer versions. When people talk about “your credit score” in general terms, they’re usually referring to FICO Score 8 or something close to it.
Base FICO Scores range from 300 to 850. But FICO Score 8 isn’t the only game in town. FICO has released newer models, including FICO Score 9 and FICO Score 10, and each lender decides independently whether and when to upgrade. Some adopt new versions quickly, while others stick with older ones for years. This is why your score can look different depending on where you check it.
Mortgage Lenders Use Specific Required Models
Mortgage lending is the most regulated corner of credit scoring. For loans backed by Fannie Mae and Freddie Mac, which cover the majority of conventional mortgages, the Federal Housing Finance Agency dictates which scoring models lenders must use. Historically, mortgage lenders have been required to use older FICO versions (FICO Score 2, FICO Score 4, and FICO Score 5, one from each credit bureau) that are significantly behind what the rest of the industry uses.
That’s changing. FHFA announced in late 2022 that it would require a transition to FICO 10T and VantageScore 4.0 for loans sold to the government-sponsored enterprises. FICO 10T incorporates “trended data,” meaning it looks at the direction your balances and payments have moved over time, not just a single snapshot. VantageScore 4.0 is notable because it’s the first time a non-FICO model will be accepted for conventional mortgage underwriting.
Mortgage lenders also pull reports from multiple credit bureaus. FHFA permits either a tri-merge report (all three bureaus: Equifax, Experian, and TransUnion) or a bi-merge report (two of the three). When a lender gets multiple scores, they typically use the middle score for a single borrower or the lower of two borrowers’ middle scores for a joint application.
Auto Lenders Use Industry-Specific Scores
When you finance a car, the dealership or lender will likely pull a FICO Auto Score rather than the base FICO Score. These industry-specific models are tuned to predict how likely you are to default on an auto loan specifically, giving extra weight to your history with car payments and installment loans.
Several versions are in active use: FICO Auto Score 9, Auto Score 8, Auto Score 5, Auto Score 4, and Auto Score 2. Which one a particular lender uses depends on when they last updated their systems. The key difference you should know is that FICO Auto Scores use a wider range of 250 to 900, compared to the standard 300 to 850 range. That means your auto-specific score could be higher than your base FICO Score, which sometimes surprises people who check their score on a free app and then see a different number at the dealership.
Credit Card Issuers Have Their Own Versions Too
Credit card companies often use FICO Bankcard Scores, which are calibrated to predict credit card repayment behavior. Like auto scores, these range from 250 to 900. Active versions include FICO Bankcard Score 9, Bankcard Score 8, Bankcard Score 5, Bankcard Score 4, and Bankcard Score 2.
That said, many card issuers also use the base FICO Score 8 or FICO Score 9 rather than a bankcard-specific model. It varies by issuer, and companies rarely publicize exactly which version they pull. The practical takeaway: if you’re applying for a credit card, both the base FICO Score and the Bankcard Score are relevant, and either could be the one your issuer relies on.
Why the Score You See Online May Not Match
Free credit score tools from your bank, credit card company, or a monitoring service often show you a VantageScore 3.0 or a FICO Score 8. Neither of those is necessarily the score your lender will pull. If you’re applying for a mortgage, the lender is using older (or soon, newer) FICO versions. If you’re buying a car, they’re likely using an auto-specific score. The free score gives you a general sense of where you stand, but it’s common to see a gap of 20 points or more between the score on your app and the one your lender sees.
You can access many of your industry-specific FICO Scores through myFICO.com, which is the consumer-facing arm of the company that creates the scores. This can be useful if you want a closer look before applying for a mortgage or auto loan.
How Lenders Choose a Credit Bureau
Beyond choosing a scoring model, lenders also choose which credit bureau to pull from. For non-mortgage lending, most lenders pull a single bureau report. Which bureau they use often comes down to their business relationship and pricing agreements with that bureau, not anything about you as a borrower. Your scores can differ across Equifax, Experian, and TransUnion because not all creditors report to all three, and the timing of updates varies.
For mortgages, lenders pull from two or three bureaus to get a more complete picture. If you’re preparing for a mortgage application, it’s worth checking your reports at all three bureaus through AnnualCreditReport.com to catch any errors or discrepancies that could drag down your score on one bureau but not another.
What This Means for You
You don’t need to track every scoring model, but it helps to know the basics. For everyday credit decisions like credit cards and personal loans, FICO Score 8 is the closest proxy for what most lenders see. For auto loans, expect a FICO Auto Score that may run slightly higher than your base score. For mortgages, the scoring landscape is in transition, and your lender will tell you which scores they pulled during the application process.
Regardless of which model a lender uses, the factors that drive your score are largely the same across all of them: payment history carries the most weight, followed by how much of your available credit you’re using, the length of your credit history, your mix of account types, and recent applications for new credit. Improving any of those factors will lift your score across virtually every model a lender might choose.
