CEDEX
There is also a system known as CEDEX, Courrier d'Entreprise à Distribution EXceptionnelle ("special business mail"), 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:
- 12 rue de Broquedis
- 64205 Biarritz CEDEX
CEDEX should always be written in capitals. It may be followed by a number, if the town has more than one post office, or if it is split into arrondissements.
Ordinary deliveries would be addressed to:
- 12 rue de Broquedis
- 64200 Biarritz
It is acceptable to include a boîte postale (post office box) number as well as the street address in CEDEX addresses.
