For this season- Only if they are also a member of EFC. You can’t just transfer a ST to anyone. I tried and couldn’t do it. I called the club and they said in this last season at Goodison they have introduced a policy to give EFC Members priority for any resale ticket transfers. That’s what I was told and because of this i was unable to transfer my ticket digitally to the person who sits next to me in the game because he wasn’t a member, just a ST holder. If you have a ticket transfer planned in the future to give to a family member of a friend they have to have a supporter number and EFC Membership. Check what is needed to be in place with the club first.
If anyone has managed to digitally transfer a ticket to a non member this season then I don’t know how you’ve managed it.
