Postal reference data

Validate your postal addresses against the reference data

For France


Cap Adresse software tools use La Poste’s geographical reference data to validate addresses.

The compressed and indexed reference data files are sent to our customers every month once they are updated by the Service National de l’Adresse (SNA, a subsidiary of La Poste).

Reference data files supported by Cap Adresse solutions:

Hexaposte - Hexavia - Hexaclé - Hexaligne3 - Cedexa - Roudis 2000
