When you open a new credit card, you may notice that your credit score has lost a few points. This is because opening a new line of credit will ding your score a few points. This typically happens because when you apply for a credit card, the card issuer or lender will review your credit information and do a hard check, or a hard pull of your credit history.  Whenever you undergo a hard check, you will lose a few points, as you are applying for credit. This happens whether you are approved or not for the credit card. This is often because people may apply for multiple credit loans from a variety of sources, and have to undergo multiple checks.  Whilst having a new credit card will decrease your credit score a little, this is usually only temporary, as you can use your credit card to build up your credit score, as long as you use it responsibly.
