With this in mind it is essential to routinely check your credit report for errors. Fortunately, you can do this 3 times a year for FREE. One time per year at each of the credit reporting agencies, Experian, Equifax and TransUnion.
In the US, the Fair Credit Reporting Act and its amendments require that any national consumer credit reporting agency (including Experian, Equifax, and TransUnion) and any national specialty consumer reporting agency (including Innovis, PRBC, Teletrack) provide a free copy of the credit reports for any consumer who requests it, once per year
Free annual credit reports for Experian, Equifax and TransUnion may be requested at https://www.annualcreditreport.com. Note that many imposter websites with names similar to www.annualcreditreport.com exist, and users will see promotions for extra credit-checking services that cost money. Carefully following the process and declining for-pay services will allow users to get their free annual credit reports. Also note that the free reports do not include the consumer's credit score. Rather, they provide a list of accounts so users can confirm that no erroneous information is on the reports. Excerpt from Wikipedia
