There are several different kinds of credit scores. FICO prepares their official scores using several different models, and using information from each of the 3 credit bureaus, so you may have several slightly different FICO scores depending on which model is used and which credit bureau is the source.
Intuit offers Turbo®, an app and web site for monitoring your credit, that uses a "VantageScore" from Transunion. It is similar to but not identical to a FICO score. You can get your VantageScore for free by enrolling in Turbo®.
Some credit cards will show customers their FICO score for free. Otherwise, if you want to see your FICO scores, you will probably need to go to one of the three credit bureau web sites and pay for a subscription.
