The Schengen Agreement
Denmark is part of the European Union's Schengen Agreement, which means that you do not need to show your national ID card or passport when you are travelling to or from Denmark from another Schengen EU country. You are still recommended to bring your passport or ID card with you in case you need to prove your identity. Some airline operators still require you to present a passport even for travels within the Schengen area.
The following countries are part of the Schengen Agreement: Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden and Switzerland.
