FICO does offer a package called Score Watch, which is basically a 30-day free trial. When you sign up for Score Watch, you get a free FICO score and credit report. You will eventually be charged if you don't cancel, however, FICO will continuously remind you over the course of the 30 days that your free subscription is running out, so hopefully you won't end up forgetting.
The three major CRAs are private, for-profit companies and they don’t share information with each other. That means there can be a mistake on one report but not another. This is why it’s important to review all of them for any errors (more on disputes in a minute). Meaning, when you monitor one report, you need to take a look at the other two as well.
Only one website is authorized to fill orders for the free annual credit report you are entitled to under law — annualcreditreport.com. Other websites that claim to offer “free credit reports,” “free credit scores,” or “free credit monitoring” are not part of the legally mandated free annual credit report program. In some cases, the “free” product comes with strings attached. For example, some sites sign you up for a supposedly “free” service that converts to one you have to pay for after a trial period. If you don’t cancel during the trial period, you may be unwittingly agreeing to let the company start charging fees to your credit card.
