When you sign up with NerdWallet, you get access to your TransUnion credit report. It's updated weekly, and you can check it whenever you want. You also are entitled to a free report every 12 months direct from each of the three big credit bureaus (the other two are Experian and Equifax) by using AnnualCreditReport.com. Because credit reports update far more frequently than once a year, it’s smart to monitor them at least monthly.
There’s a misconception that your credit report is a computer file that sits at a credit reporting agency and gets periodically updated. But it doesn’t quite work that way. When someone requests your report, the credit reporting agency’s computers go to work, compiling information that matches your identifying information with a report that can be scored or provided to the lender, insurance agency or other company that purchased it.
Annualcreditreport.com and the nationwide credit reporting companies will not send you an email asking for your personal information. If you get an email, see a pop-up ad, or get a phone call from someone claiming to be from annualcreditreport.com or any of the three nationwide credit reporting companies, do not reply or click on any link in the message. It’s probably a scam. Forward any such email to the FTC at email@example.com.
