During checkout, on the payment page, click the + symbol next to GIFT CARD to expand and reveal the fields to enter the Card Number and PIN. Note: The PIN (personal identification number) has up to 6 digits, and it's included in the email of the e-gift card. Cards purchased from Indigo start with 604xxx and have a 19 or 20-digit number. Cards purchased from third parties may have 11 digits in front of the 604xxx, which should be omitted when entering the card number. When prompted, enter all 19 or 20 digits, without any spaces or dashes.
