Why I am not able to add my new card to wallet

Hi harshvir288,

Thanks for coming to Apple Support Communities for help today.

Have a look at this page: If you can't add a card to Apple Wallet to use with Apple Pay, It's likely you will need to contact the card issuer.

"Learn what steps to take if you can't add a card to the Wallet app to use with Apple Pay.

1. Check that you're able to use Apple Pay:

• Contact your card issuer to see if they support Apple Pay.
• Update to the latest version of iOS or iPadOS, watchOS, or macOS.
• Make sure that you are in a supported country or region.
• Check that your device is compatible with Apple Pay.

2.Check for services outages or connection issues.

3.If you see the message "Could Not Add Card" or "Invalid Card," contact your bank or card issuer.

Apple does not approve or decline cards for use with Apple Pay. If your card was declined, contact your bank or card issuer.

If you need help adding a card, learn how to set up Apple Pay."

Have a fantastic day!
