I can only see the last 4 digits on my Apple Card number, how do I find the whole thing?

The instructions in How to find the card numbers associated with your Apple Card - Apple Support do display the full number for the Apple Card. I just tested it again now before responding.

For cards other than the Apple Card you can only see the last 4 digits in the Wallet app.

There is no full number to have. And you don't really need it for anything.

If you are trying to use the Apple Card online you can generate a virtual number from the Wallet app to use online which you can cancel at any time. It will be different to the Device Account and Apple Card number you get the last 4 digits for.

For returns you only need the last 4 numbers.

See the instructions here, How to find the card numbers associated with your Apple Card - Apple Support Remember you cannot open the wallet like you are going to make a purchase, you have to just open the Wallet app. Then tap on the card icon with the "123" in it, and you will see the card number there.
