Yes, the ticket is nominative. All ticket codes must be associated with the name of the person who will use it.
But if you ultimately cannot attend the festival and want to transfer it to someone else, in the email you received with your ticket there is the option to change the name, in the ‘manage my ticket’ section. You also can contact the staff of Tickety (922 38 82 88 / incidencias@tickety.es) to complete the process.
Admission will depend on you presenting the ticket in good condition, that is, any ticket that is presented with signs of falsification will allow the organizer to deprive the person presenting it of access.
