• Coverage: mainland France, Corsica and the overseas departments.

Finding an address

• A postcode and house number don't identify a French address. Autocomplete needs the postcode, settlement and street.
• streetNumber is a number. The repetition index after it (indice de répétition) is the premise: bis, ter or a letter, as in Rue de la Baume 10 bis in Antibes. Infer reads it from a line such as 75001 1 bis.
• House number 0 exists: Rue du Bief 0 in Géovreisset is a real address.

Address fields

• commune and settlement: both hold the commune. In Paris and Lyon the commune is the arrondissement, such as Paris 1er Arrondissement.
• department: the département, such as Alpes-Maritimes.
• region: the région by its current name, such as Provence-Alpes-Côte d'Azur.
• Suggest on a postcode lists every commune it covers.
