What is your credit score?
You actually have more than one credit score. Credit scores are calculated based on the information in each of your credit reports. Companies that you have an account with may not report credit related information to all 3 of the credit reporting bureaus
The information that each of the 3 credit reporting bureaus is different and the formulas or algorithms used to calculate your credit scores are different. Therefore your credit score from each of the companies will be different.
