The apple website says this

iTunes says my code is "invalid".
When iTunes says that a code is "invalid" it usually means that one or more of the characters that you've entered into the redemption field are incorrect. If your code is not accepted at the iTunes Store, make sure that you've entered the code exactly as it appears on your card.

Please read your code carefully. The following letters and numbers can look very similar:

The letter A and the letter H
The letter B and the number 8
The letter D and the number 0
The letter E and the number 3
The letter G and the number 6
The letter H and the letter W
The letter J and the number 1
The letter M and the letter N
The letter O and the number 0
The letter P and the letter F
The letter Q and the letter O
The letter Q and the number 0
The letter S and the number 5
The letter S and the number 8
The letter V and the letter U
The letter Z and the number 2
If you're still unable to redeem your gift card after verifying the characters in the code, please email us using the form at the bottom of the page. Make sure that you include the serial number from the back of your card. See the section below on locating the serial number for your iTunes Gift Card.
