Certification

Customer data changes and degrades over time: the average lifespan of a database is about two years. In fact, about 200,000 roads are renamed or deleted in France each year.

To ensure that companies have access to high quality customer data, La Poste holds a range of geographical data files (commune and postcode files, road name file, etc.). To ensure reliable correction and optimal use of addresses, the reference data must be coupled with quality computer processing.

Accordingly, La Poste, in association with the FEVAD (Federation of Distance Selling Companies) and the SNCD (National Union of Direct Communication), has set up a RNVP Software Certification Committee (RNVP = Postal Address Restructuring, Standardisation and Validation).

The certification involves processing a file of 1,000 dummy addresses. The results are then studied in detail by the Service National de l'Adresse. For certification, no more than 5 addresses may be distorted. This benchmark certification, which is renewable every two years, is exclusively awarded to the most efficient RNVP software.

Our Cap Verif and Cap RNVP software are certified by the sna
