Checking Your Own Credit Does Not Affect Your Credit Score
Your credit scores are determined by formulas that assess your creditworthiness. Lenders evaluate the risk of extending credit to you in part by using credit scores, which measures your credit risk — namely, how likely it is that you’ll pay them back and pay on time. Credit scores constantly adjust as the information in your credit report changes. You’ll benefit from knowing your Experian, Transunion, and Equifax credit scores and keeping track of changes and setbacks.
A credit score is an additional service that can be requested when getting your credit report. Along with your credit score you will know what factors influence your risk.
