If you haven’t already, I recommend getting your free credit report. By law, you’re allowed to view your credit statement one time per 12 months. The website is: http://www.annualcreditreport.com.
This is not your credit score, but instead gives you a list off all the accounts that are open in your name. For an extra $5 to $10 each, you can get your actual credit score from one (or all) of the credit bureaus.
