Do I need to know all three of my credit scores?
Credit information is often not reported with the same accuracy across all three credit bureaus. so it is important for consumers to check each report and score. The three credit bureaus are Experian, Equifax and TransUnion, and each one of these agencies carries a report that is independent from the others.
Some creditors and collectors only report to one or two agencies, while some items get disputed off one report but verified on another. Items also get removed from one or two reports for various reasons. This variation often means a large credit score difference from bureau to bureau. When a credit score is requested, it is calculated based on what is in that particular credit report. So while a consumer may have an good credit score based on one
report, he or she may have a bad credit score based on another. For example, if a consumer has two collections on report A and none on report B, the score calculated from report B is going to be higher than the one calculated from report A. This is why lenders who offer large loans such as home loans usually pull all three credit reports and base the approval or denial on the middle score.
If a consumer is denied credit based on one bad credit score but has a better credit score with another bureau, he or she may have luck calling the creditor and asking for the better score to be considered, especially if there is a good reason why the first credit score is so low.Source: www.investopedia.com
