My Question or Issue

I recently did a writing commission for someone and rather than money I received a code for a 3-month Spotify Premium subscription. Though, when I've tried to input the code under "redeem" on my profile, it says that "the code doesn't seem to be valid". It's not a pin, but a 13-digit code containing mostly letters. I'm not sure what to do to make it work to get my subscription, and neither does my commissioner. Can someone tell me what to do?

Hey @Vodnici,

Thanks for reaching out.

Let’s try a few things:

• Make sure you're entering the code correctly. For example: try 0 (zero) instead of O, and I instead of l (lower case L).
• Check the code hasn’t already been redeemed. You can check it on this page. 
• Check the country registered to your account is the same as where the gift card was purchased. 
  Tip: Check out Spotify's guide to changing your country settings.
• If you bought your gift card from a store, it might not have been activated when purchased. Please return to the store and ask them to activate it.
• Codes are not redeemable for Premium for Family or in conjunction with other discounts and promotions.

Let me know how it goes.
