The new digital Entry/Exit System (EES)

In Autumn 2024, non-EU nationals, including UK nationals, visiting the EU will need to create a digital record when entering the EU’s Schengen Zone. This includes providing biometric data (fingerprints and facial image) at the border.  UK nationals with rights under the Withdrawal Agreement will be exempt from EES registration if they have the correct documentation.

For more information please see EES EU Commission Factsheet.

The UK Government also provides  important information and outlines what you’ll need to know and what documents are accepted.
