Like any card, your physical card has an expiry date that is printed on it.
The card and any Account Number linked to the card will no longer be usable after the expiration date but you will still be able to receive and send funds to and from the account associated with the card.
Please check the expiration date of your card in advance and order a replacement card as it takes time to be delivered. You can find more information about it in this helpguide.
