In 2006 CarrefourOnline started using DEYDE services to normalize and improve the names and addresses of their client database and they have used the service ever since.

The project was established in two phases. The first phase consisted in receiving CarrefourOnline’s old client database to apply the following normalization services: name normalization, address cleansing and alphabetical duplicate identification.

In a second phase, they incorporated DEYDE WebService in Carrefour’s online shopping website, so that client addresses would automatically get normalized and corrected when entered in the website by the client. According to a press release published in 2006 by CarrefourOnline’s Client Service Manager:

“With DEYDE, we have improved our service, minimizing returns on delivery due to incorrect client addresses. In many cases, fundamental information such as postal codes or street types were incorrect. Traditionally, those mistakes would lead to many returns on delivery, which generated important economic loss and resulted in client losses because they would not get their orders on time. This situation has greatly improved with the integration of the online address normalization. “
