Quick overview: Why the "score name" matters
When a lender approves or denies your loan, the numeric score they used isn’t the whole story — the scoring company (FICO vs VantageScore), the specific version (for example: FICO Score 8, 9, 10T, or a BNPL‑enhanced variant), and even industry‑specific versions (mortgage, auto, bankcard) can produce different outcomes from the same credit report. Knowing the exact version helps you interpret a denial, target fixes, and challenge errors effectively.
In 2024–2025 the industry continued shifting: model vendors have released BNPL‑aware products and lenders have begun pilot testing newer VantageScore variations — meaning it's increasingly important to ask for the exact model and version when you receive an adverse action.
Which models are lenders actually using today (short answer)
Most lenders still rely heavily on established FICO versions (for many consumer credit decisions FICO Score 8 and FICO Score 9 remain common), while mortgage underwriting and some other markets use newer or industry‑specific variants. FICO recently announced BNPL‑aware versions (FICO Score 10 BNPL and 10T BNPL) that were made available for lenders to adopt, and adoption timelines vary by lender and loan type.
VantageScore's current mainstream model is 4.0; VantageScore has also been piloting an open‑banking / "4plus" variant for lenders interested in cash‑flow or open‑banking data. Regulators and large institutions (for example the FHFA) have been working with VantageScore 4.0 for certain mortgage reporting and analysis, which has increased VantageScore 4.0's visibility in mortgage channels.
At a glance — common names you might see
| Model / Version | What it means | Where you might encounter it |
|---|---|---|
| FICO Score 8 / 9 | Widely used general consumer models; 9 treats medical collections and some small negatives differently | Credit cards, personal loans, many lenders' underwriting |
| FICO Score 10 / 10T / 10 BNPL | Newer versions; 10T uses trended data; 10 BNPL incorporates buy‑now‑pay‑later activity where reported | Lenders piloting modernized risk views; auto, bankcard, and some consumer loans |
| VantageScore 3.0 / 4.0 / 4plus | VantageScore 4.0 improves treatment of thin files and uses trended data; 4plus adds open‑banking/cashflow inputs in pilots | Some card issuers, mortgage tri‑merge products, lenders using VantageScore |
How to find the exact score and version your lender used
If you were denied (or received a less favorable rate) the law gives you ways to find the number and the model: under the FCRA and related rules, a creditor that takes adverse action because of information in your credit report must give you certain information — including the numerical credit score used, the range of possible scores, the name of the scoring model, the date the score was produced, and key factors that adversely affected the score. Ask for and save the adverse action notice (or request a written explanation if you only received an oral denial). The CFPB explains these rights and how to request the reasons behind a denial.
Step‑by‑step: What to ask and how to ask it
- Request the adverse action notice in writing if you don’t have it — it should include the score, model name, date, and key factors.
- If the notice lacks the model name or date, reply in writing: "Please provide the numerical credit score, the name and exact version of the scoring model used, the credit reporting agency (Experian/Equifax/TransUnion) that supplied the score, and the date the score was generated."
- Ask the lender which bureau provided the score and request a copy of the tri‑merge credit report if appropriate for the loan type (mortgage lenders commonly use tri‑merge reports).
- If the lender used an AI/predictive model component, ask for model documentation or a meaningful explanation of the features that caused the decision (the CFPB has emphasized stronger explanations for automated decisions in recent guidance).
Keep records: send requests by email and certified mail, save responses, and note dates and names of representatives.
Interpreting results and next steps
Once you know the model and version, you can:
- Compare the lender’s score to the consumer score you can get from each bureau (models differ — the same report scored by FICO 8 vs FICO 10T can produce materially different numbers).
- Look at the "key factors" the lender provided and address them (e.g., reduce utilization, correct misreported accounts, add missing on‑time tradelines).
- If you find errors on the credit report that impacted the score, file disputes with the bureau(s) and send evidence to the lender explaining why the report changed after correction.
- If the lender used a BNPL‑aware score and you do or don’t have BNPL reporting on your file, understand that those models will treat BNPL accounts differently and adoption is still uneven — some lenders may not yet use BNPL‑aware scores even if the vendor offers them.
When to escalate
If a lender refuses to provide the required adverse action details or the explanation is incomplete, you can: (1) ask the lender to confirm in writing, (2) file a complaint with the CFPB or your state consumer protection agency, and (3) consult a consumer‑credit attorney for complex disputes.
Finally, remember that model adoption varies by industry and lender. Knowing the exact model version used — and whether BNPL or open‑banking inputs were included — gives you the best chance to interpret a denial accurately and take the right corrective steps.
