Different times are foreseen according to the delivery method selected during the purchase phase, the type of ticket or the provisions for each individual event. If you do not find the box for the "Change Name" within your order, it means that the service is no longer available or that it has not been activated yet. In any case, when making your request, the expiry date for this service will be displayed.
Few days before the event day the service can be closed for organizational reasons.
