The following is a list of border crossing points in France (French: points de passages frontaliers, or "PPF") forming the external border of the Schengen Area. By contrast, the term points de passages autorisés ("PPA") refers to the crossing points at the border between France and other Schengen countries (i.e. internal borders of the Schengen Area). PARAFE self-service gates have been installed at a number of border crossing points to facilitate passage for eligible travellers (European Economic Area, Andorran, Monegasque, San Marinese and Swiss biometric passport holders aged 18 or over).
