How many codes to redeem per account ( apple tv , apple music …)

Hi there Samoxx,

We can provide some information.

If you or a family member already redeemed the offer, you can't redeem it again.

Have a look at the details in this link to learn more: If you can't redeem your promotion for an Apple subscription - Apple Support

If you have any more questions, you'll want to reach out to Apple Support directly. They're best-equipped to take a closer look at your account and provide some additional guidance. This link will help you get started: Apple Support

Take care.
