There's also http://creditkarma.com, which allows you to check your Transunion-based creditkarma version of your credit score. Note that it's not actually your credit score, but an estimate based on all the information Transunion provides (debts, % of monthly payments made, debt utilization ratios, etc.). You can check it as many times as you want, and it doesn't hurt your credit score. It doesn't count as a "hard inquiry," but as a "consumer inquiry," so it doesn't count against you.
