Yes, you really can get your credit report for FREE! However, most sites that offer "free" credit reports are doing so with strings attached. If they ask you for credit card info, just exit away from it.
There is no need to pay for credit monitoring or credit scores. You have the right to recieve your credit report for free from the credit reporting bureas once per year upon request. The easiest way to do this is to go to annualcreditreport.com amd fill in the proper information. The site is truly free and you will get a report from all three major credit reporting bureaus. They will offer you other services, but for now, just focus on getting a copy of the credit report so that you can review it for possible errors or identity theft.
Once you have reviewed them you will be on the way to repairing your credit!
