What does it mean CEDEX in french addresses?

Answer 1

CEDEX ( stands for "Courrier d'Entreprise à Distribution EXceptionnelle" ) is a system , designed for recipients of large volumes of mail.

A postal code is allocated to each large organisation or to post office box holders, ending in three unique digits, for example:

2, place Jussieu
75251 Paris Cedex 05

The '05' is for the Ve arrondissement. Ordinary deliveries would be addressed to:

2, place Jussieu
75005 Paris

It is also acceptable to include a boîte postale (post office box) number as well as the street address in CEDEX addresses.
