iTunes for Mac: Redeem an iTunes allowance, gift certificate, or Gift Card

If you received an iTunes Store allowance, gift certificate, iTunes Gift Card, or promotional code, you can use it to buy songs, videos, or audiobooks from the iTunes Store.

You need to set up an Apple ID before you can redeem anything in the iTunes Store. You don’t need to enter credit card information to redeem only the amount of a gift certificate or card.

You can use a gift certificate only in the iTunes Store for the same country in which the certificate was purchased.
