Available credit shows $0.00

Is there a reason it should not be $0.00?

Are you consfusing Apple Account Balance with Apple Credit Card credit limit?

If you are referring to your Apple Account balance, it would only be greater than $0.00 if you have added funds to your account in some way, either to direct fund addition or via an Apple, iTunes or App Store gift card.

Have you added balance to your account at any point?

If you have, have you since bought anything, or did you maybe have a pending charge on your account that may have used it up, if you did in fact add any balance to it?

Pending charges will be automatically charged if there is enough balance for them on your account.

If you provide details and context about why you think the $0.00 is wrong, someone may be able to advise.

Maybe because you have no balance in your account? I don't.

*If your Apple Account balance seems incorrect

• If you think that your Apple Account balance is incorrect, sign out of the App Store, Apple Music app, or Apple TV app. Then sign in and check the balance again.
• If you still think that the balance is incorrect, check your purchase history to see whether you bought an item or a subscription renewed.

If this isn’t the issue …please post back with more details?
