Regarding endwalker OST purchase

Sorry this isn't new player game related but not sure where else is more appropriate to post this.
I would like to ask that for Endwalker OST, if my account region is NA, is the code I get for the minion usable in my account if let's say I order it from Japan?

I ordered the Shadowbringers OST from Japan and was able to apply the minion code to my EU account.

Thanks a lot mate
