If you’ve been turned down for a credit card, your credit card issuer should explain why and they usually do it in writing. So, to know the reasons for your denial analyze the letter of explanation mailed to you. Bear in mind that you are entitled for a free copy of your credit report and your credit score used by your issuer. Check this credit report and correct any inaccurate information.
Please note that too many new applications submitted over a short period of time can also be a reason for rejection.
If your application is denied, consider a co-signer or apply for a secured credit card.
