So, I’m a little confused too! Typically if you were looking at VantageScores from the three credit bureaus, the numbers would be quite similar. There usually wouldn’t be that 20+ point gap between your Experian and Equifax scores, particularly if they were pulled on the same day. (That’s different from FICO scores, which can differ a fair amount depending on the bureau. VantageScore’s “consistency” is one of the attributes the bureaus highlighted in their early marketing of the product.)
Even though the credit bureaus created the VantageScore model and often do provide VantageScores to credit monitoring services, they also may provide FICO scores and their own proprietary scores, depending on the service. So there isn’t one score that’s provided directly by the bureaus–all scores come from bureau data, but may be created using different formulas.
If you let us know which credit monitoring service you’re using, we may be able to provide more insight on why you’re seeing such different numbers.
