If you’re like most people, you probably have two or more cards in your American Express account. But if you want to add another card, there are a few things you need to do. First, open your American Express account and click on the “My Cards” tab. This will show all of your cards in one place. Scroll down and find the card that you want to add. If there are any other cards in your account that are also linked to American Express, they will be listed next to the card that you want to add. Next, enter the information on the card into American Express’ online form. You’ll need to provide your name, address, and credit score. You can also choose a security code if you want extra protection for your card. Once everything is complete, click on “Add Card.” You’ll be taken to a page where you can review your new card’s details and make any necessary changes. Once everything is complete, click on “Submit.”
