Apart from your ticket in a printed or e-ticket format, you should always have your ID card, passport, or any other identity document with you, especially on international ferry routes. Please note that for some regions and depending on the period of stay, you may additionally need a Visa. Always check your destination's official government website and our blog for further information. You may be asked to present the document to the ferry crew or port authority to confirm that you are the legal ticket holder.
If you have purchased discounted ferry tickets, you will be required to provide a document confirming that you are eligible for the specific discount (e.g. student card, ISIC card, etc.). For more information please visit our 'Discounts' page.
