Xbox live and game pass codes

Dear Support,

Thank you for the fast reply!

Er...my question is that a 'xbox game pass ultimate 14 days trial codes' could be used/sold as 'xbox game pass 14 days trial code' or 'xbox gold live 14 days trial code', right?

I understand that a xbox game pass 14 days trial code or a xbox live gold 14 days trial code can't be used/sold as xbox game pass ultimate 14 days trial code for sure.

Because a 'xbox games pass ultimate 14 days trial code' equals a 'xbox game pass 14 days trial code + xbox live gold 14 days trial code', so for new Microsoft/Xbox accounts, a 'xbox game pass ultimate 14 days trial codes' could be used/sold as 'xbox game
pass 14 days trial code' or 'xbox gold live 14 days trial code' , right?

Please help to clarify.

Thanks again for your time!

You can add the Xbox Live Gold and Game Pass code then upgrade to Ultimate. The Ultimate will automatically be extended by the amount of months of the Xbox Live Gold plus the amount of months of the Game Pass code.

If you had Xbox Game Pass Ultimate already active before you redeem that code, when you enter a code for Xbox Live Gold or Xbox Game Pass it will add as Game Pass Ultimate and not only Xbox Game Pass, is this your case?

How to setup an Xbox LIVE pass code:

You are not forced to use ultimate. If you wanted to go back to Xbox Live Gold you needed first to cancel the ultimate subscription, and then insert the code. For all users, with xbox game pass ultimate active, when you submit a xbox live/xbox game pass
for console/ xbox game pass for pc codes it will automatically convert in xbox game pass ultimate months using the established ratio.
