"Invalid PIN. Please try again."
If you see a message that your code is invalid, it typically indicates that there was an issue with the code you entered. Double check the code at the back of the card, your email or store receipt and try again.
If your code was entered correctly but you are still seeing this message, it may mean that your card has not yet been activated by the merchant. Please wait 24 hours before attempting to redeem your gift card again.
