Where can I apply my Apple promo code to my Apple Music account?

Hi claytonclay70,

Thanks for using Apple Support Communities. We understand you have some questions about redeeming a code for Apple Music. We're happy to help.

You can redeem that in Apple Music. Tap Listen Now at the bottom, then your profile picture in the top right. From there you should see the option to "Redeem Gift Card or code".

Thanks.
