Not Using Your Credit Card
Often times people will get an offer in the mail where they can sign up for a new credit card and get thousands of frequent flyer miles as a reward. They sign up, get the card, and never use it. This can be bad news for your credit score. If you have a credit card account in good standing that doesn’t have any activity over a long period of time, your credit card issuer could choose to close your account because of inactivity. If you’re not using it, you may not notice that your account has been closed until your credit takes a hit. The reason this would hurt your score is that it would be bad for your credit utilization ratio.
