A lot of sites will give you a credit score. Most people don't know you have multiple scores. FICO tends to be used more than VantageScore, but some say that's changing. They're all worth paying attention to, but FICO is likely to be the one a creditor will pull when you apply for loans and stuff. Each service below has different features, you can find them on their respective websites.
I've only found one that gives you a FICO score.
- Discover Credit Scorecard - Discover will give you your Experian FICO score
This is the one I tend to use the most, simply because FICO is used more than VantageScore. That said, this is only one FICO score from one beauru, Experian. It's pretty basic. Sign up, answer some questions, and you'll get your score. No bells and whistles, but it gets the job done.
