Do I need to put a credit card for a code?

when i add xbox gamepass ultimate redeem codes to my kids xbox ones they never get asked for a card, it asks do you want to enable auto renew, i say no and then the code is accepted and thats it done.

Yeah, but it's in a another account, and never paid anything on that account :/that why it's not working maybe...

Hi, i am an xbox member for 17 years. This is what i do with no credit card. You can go to any store that sells xbox money cards. I think they are available in $20 or $50 value. Once you buy what you need then redeem the code(s) to your account. Your account balance will reflect the new money, this can now be used to purchase your xbox game pass ultimate membership. Hope this helps you!!👍😊

Hi thanks for your answer, that actually how I do it when I don't want to use all my Microsoft Reward Points, I buy 10-30 dollars /euros of gift card, but I need to go to a store for that, and there not a lot of store where I live, where I can found gift card at 10-30 €/$ :/ so that why I asked if there is not a another solution at that problem

OK ! Thanks for your answer
