There’s no single credit score. Different companies, versions and credit bureaus produce different numbers from the same habits.
Quick summary
- FICO and VantageScore are the two main credit scoring companies in the U.S., and both use a 300 to 850 range for their main scores.
- Each company has several versions, and lenders don’t all use the newest one.
- Scores can differ by bureau because Equifax, Experian and TransUnion may hold slightly different information.
- The habits that raise one score, like paying on time and keeping balances low, raise the others too.
If you’ve checked your credit in two places and seen two different numbers, nothing is wrong. Several scoring models exist, and each one reads your credit reports in its own way.
Two companies, many versions
FICO scores are made by Fair Isaac Corporation and have been used by lenders for decades. VantageScore was created in 2006 by the three nationwide credit bureaus as an alternative. Both companies update their models from time to time, so several versions are in use at once.
- Base FICO scores and VantageScore 3.0 and 4.0 all run from 300 to 850.
- FICO also offers industry-specific scores, such as auto and bankcard scores, with a wider 250 to 900 range.
- Older versions stay in use for years because lenders have to test and approve new models before switching.
Why the bureau matters too
A score is calculated from one credit report. Equifax, Experian and TransUnion don’t always hold identical information, since not every lender reports to all three. The same model can give a slightly different number depending on which bureau’s report it reads.
| Source of difference | Example |
|---|---|
| Scoring company | FICO vs. VantageScore |
| Version | FICO Score 8 vs. FICO Score 10 |
| Credit bureau | Experian report vs. TransUnion report |
| Timing | A balance reported last week vs. today |
How the models differ
The models weigh the same building blocks: payment history, how much of your available credit you use, the age of your accounts, new credit and the mix of accounts. They differ in details, such as how they treat paid collection accounts or how much history they need. FICO generally needs at least one account that’s been open for six months, while VantageScore can score people with a shorter history.
Quick tip
Free scores from card issuers and apps are useful for tracking trends. Note which model and bureau they use, so you compare like with like over time.
What stays the same
Whatever the model, the same habits help:
- pay every bill on time
- keep card balances low compared with your limits (see credit utilization)
- apply for new credit only when you need it (see hard and soft inquiries)
- check your reports for errors
Making sense of your numbers
Treat each score as a reading rather than a verdict. If two scores move in the same direction, your habits are working. For the ranges lenders use to describe scores, see what counts as a good credit score.
Reader questions
Which score do lenders use?
It depends on the lender and the type of credit. Many card issuers and auto lenders use FICO versions, some use VantageScore, and mortgage lenders follow their own industry requirements.
Why is the score in my banking app different from my lender’s?
The app may show a different model, version or bureau, or it may update on a different day. A gap of a few points, or more, is normal.
Do I need to check every version?
No. Watching one score over time tells you the direction you’re heading. Checking your credit reports matters more than chasing every number.
