How can I see the code on my Apple gift card that mistakenly scratch some number

If you can't read the code on the back of your card because it's scratched or damaged, Contact Apple Support.

Keep in mind, you might need to provide:

• An image of the full front and back of your card.
• A sales receipt showing when your card was purchased.
• The serial number from your card. 

Also, do not post your gift cards on a public forum.
