To qualify for a Sam's Club credit card, you will need a credit score of at least 700. This is the minimum credit score required to get approved for any credit card, so if your score is lower, you will need to work on improving it before you can apply. There are several different ways to improve your credit score, but the most important thing is to make sure you always pay your bills on time. If you have any outstanding debt, try to pay it off as quickly as possible. And if you plan to apply for any other type of loan in the future, be sure to keep your credit usage low.
