To transfer FIFA points from FIFA 22 to FIFA 23, you must log in to FIFA 23 on your console or PC for the first time. A pop-up message will appear asking if you would like to transfer FIFA points to FIFA 23. Be aware that the pop-up message option to transfer points will only appear once, so you will not have the option to transfer FIFA points again.
The transfer is unavailable on the FIFA companion app, so you will have to launch FIFA 23 from the console or PC account you intend to play on. The transfer is irreversible, so be careful if you are playing on the EA Play trial because you will not be able to get your points back if you do not get the full game.
