The child must have a travel document when travelling abroad.
Every EU citizen is required to have their own travel document (passport or ID card). Citizens of the Nordic countries can travel to other Nordic countries without an official travel document regardless of their age. In this case, we also recommend that you take an official document issued by an authority so that you can prove your identity to the authorities if necessary. In addition, you should check which documents are approved by your airline or other transport provider in order to prove your identity.
Third-country nationals under the age of 16 may be included in the travel document of a guardian and travel with the guardian if the guardian’s passport states the name and year of birth of the child and, if the child is seven or more years old, a photograph of the child.
Due to the vulnerable position of children, border guards at the external border crossings must pay special attention to minors, irrespective of whether they are travelling with an adult or alone.
