The bands
300–579 poor. 580–669 fair. 670–739 good. 740–799 very good. 800–850 exceptional. Moving up a band usually matters more than moving a few points inside one.
Why your scores differ
There are many scoring models and three bureaus. Lenders may pull only one bureau, may use an older model version, and may use industry-specific versions tuned for auto or mortgage lending. Different number, same underlying file.
What to watch instead
Track the direction of one score over time and the accuracy of the report behind it. Chasing exact numbers across apps wastes energy.
