Parisian postal codes are composed of five digits, the first two being the number of the "departement," which for Paris is 75, and the last three representing the district. Paris is divided into 20 districts known as "arrondissements."
Each district has its own postal code, with the exception of the 16th district, which has two postal codes representing the north and the south. The Champs Elysées is in the eighth district, so the postal code is 75008. The postal code of the 16th district is 75016 for the southern part and 75116 for the northern part. The postal code should be written on the last line of the address, followed by the name of the city or town in capital letters.
