Running Another Person's Credit Report

The Federal Trade Commission says

Access to your file is limited. A consumer reporting agency may provide information about you only to people with a valid need -- usually to consider an application with a creditor, insurer, employer, landlord, or other business. The FCRA Fair Credit Reporting Act] specifies those with a valid need for access. 

A Summary of Your Rights Under the Fair Credit Reporting Act

I'm not sure how you can stop people from checking your report by faking a reason.  But you should call the credit bureau or a consumer protection agency if you think someone checked without a reason.  (You have to stand up for your rights!)

Yes you/they can! How do you think you get all of these pre-approved credit card offers, not to mention car insurance offers? To sum it up, you can place a freeze on the access to your credit report. Your cost? $0.00. The stipulation; it costs about $10.00 to allow a company to access your credit report. Big Deal! you say? It could be a big deal next time you shop for car or renters/homowners insurance or apply for any type of credit. $10.00 bucks is only $10.00 bucks, however, for example; if your shopping for car insurance it's not uncommon to check 10 or 15 companies. I believe there may be a $15.00 fee to unblock it for a stated period of time. My advise?, contact the three credit reporting agencies on this issue and you will be an expert. Case closed? You bet! 

Yes but party has the ability to be aware.
