Your credit report and your credit score are related but distinct. The report is the raw data—the full history of your credit accounts and activity. The score is a number calculated from that data, usually ranging from 300 to 850, that summarizes your credit risk at a glance.
Checking your credit report does not hurt your credit score. This is what’s known as a “soft inquiry,” and it has no impact whatsoever. Only “hard inquiries”—which happen when a lender checks your credit as part of a lending decision—can have a small, temporary effect on your score.
