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

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. 

(See the article above for illustrations of which number on the card is the serial number.)
