Multiple-day tickets may also only be used by one person. Important: Because online tickets are only valid for a specific individual and are not transferrable, you may be required to present an official photo ID at the fair. Every validated barcode is recognized as such by the electronic access control system, and ticket-holders who try to use a copied online ticket will be denied access. If you loose your ticket and are afraid that whoever finds it might use it to attend the fair, please contact us by e-mail at registrierung@messe-munechen.de so that we can block your lost ticket.
