Three years from the day it is issued, and the date is shown with the card details next to the number and security code. There is no automatic renewal: when a card expires you create a new one, and because the replacement has a different number, anything billed to the old card — subscriptions, ad accounts, anywhere the number is saved — has to be updated. If a card is close to its expiry date and still holds a balance, close it before the date rather than after: closing returns the remaining balance to your wallet in full with no fee, and frees the slot straight away so you can create the replacement.
