As the main ticket applicant, you cannot send any tickets allocated to your use to a different person. You are only entitled to send the ticket(s) from your original guest(s) to another guest(s).
Suppose you cannot attend a match for which you have purchased tickets. In that case, you may submit all your tickets for resale on the FIFA Official Ticket Resale platform accessible through your FIFA ticketing account on FIFA.com/tickets. Please note that you may not resell your allocated ticket(s) while retaining any ticket(s) intended for your guest(s).
