Yes, the entry is nominative in this edition of Phe 2024. 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 another person, in the email received from your ticket there is the option to make the name change, in the 'manage my ticket' section. You can also contact the staff at Tickety.
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.
