Can you use your Apple Card on Amazon?

For the most part, you can use your Apple Card anywhere a credit card is accepted.

You can look up the actual number of your Apple Card in the Wallet app. Tap on your Apple Card, click on the icon in the upper right corner (with the thee dots), and click Card Information. You will need to authenticate to see this information but once you do you will see your card number, expiration date, and security code.
