Can I add an authorized card user outside of the United States?
I would like to add a user in a different country and get a new card for them. Is that possible?
Question marked as
Probably not. Activating the card requires an iPhone. It cannot be activated over the phone, online or via chat. The participant must have a US Apple Account and region of his iPhone must be set to US region. The participant must also be a member of your Apple Family group.
Set up Apple Card Family and add a co-owner and participants - Apple Support
