There are three main credit bureaus (also known as credit reporting agencies) servicing the United States: Trans Union, Equifax and Experian. Each bureau is independent and a competitor of each other. Because of this there could be differences between the reports of the three credit bureaus. It is most likely, however, that the reports from the three bureaus will be quite similar because, for the most part, they use the same sources of information. If you find an error in one report it is likely the error also exists in the other reports. For that reason when you find an error you should review the reports from the other bureaus and also inform them of the error if need be. That way you can ensure that all of your credit reports are accurate and up to date.
