Too many “hard” checks of your credit can ding your score. For example, if you apply for several credit cards at once, several credit inquiries will appear on your report. Too many credit checks (as well as applying for/opening too many accounts) can give the impression that you’re a credit risk. Apply for new credit accounts sparingly, to limit the amount of credit checks you may incur.
A credit report includes information on where you live, how you pay your bills, and whether you’ve been sued or have filed for bankruptcy. Nationwide credit reporting companies sell the information in your report to creditors, insurers, employers, and other businesses that use it to evaluate your applications for credit, insurance, employment, or renting a home.
