Need help trying to sign up for Apple Card.
Would like to sign up

The support article you came here from should provide you with the steps needed to attain an Apple Card. Have you tried them all yet? If so, and they didn't help, I suggest that you contact Apple Support directly. To do so, simply select the "Get Support" link in the upper right-hand side of this forum's web page.
