How can I find the Pin for my Apple Gift Card?
I have an apple gift card and it’s asking for the pin number. Where is the pin number located on the card? Is the pin number and the code number the same?
A friendly tip: have a bit of patience when you ask a question. This isn't live chat and Apple Support does not participate in these forums. We're all just fellow users here, helping as we have time and knowledge to share, so it may take more than the very short time you waited before anyone even sees your question, much less has time to formulate a diagnosis and post a suggestion.
