The three national credit bureaus, Equifax, Experian, and TransUnion rely on thousands of outside companies to provide information for the report. They have over 200 million accounts they are responsible for monitoring. With so many accounts, errors are bound to occur. Sometimes they can be small errors like a spelling mistake, but others could have a significant impact on a credit score. To ensure there are no mistakes, people should look at their information from all three Bureaus. If there is an error, professional help should be considered, such as North Shore Advisory.
