Postcode Corsica refers to the geographic region of Corsica, France and its surrounding areas. Corsica is an autonomous region of France in the Mediterranean Sea, located off the south coast of the Italian Peninsula. It is one of the 18 regions of France and is the fourth-largest island in the Mediterranean Sea. Postcode Corsica, like all of France, is assigned the five-digit postcode system that is used to facilitate mail delivery. Postcode Corsica can be divided into seven different postal regions, each representing a specific region of Corsica. Two of the seven regions are located on the main island of Corsica and five other regions spread out over the nearby islands in the region. In Corsica, postcodes are assigned to every village, town and city represented in the postal regions, and can be divided into three cases – two digits representing the department (similar to an American state), two letters identifying the city, and a four digit figure representing the local post office or mailbox on the east side of the island. The four digits are the key component; they are used to determine the exact geographic location of the postcode. The first two digits represent the x-coordinate and the latter two digits represent the y-coordinate. For example, the postcode for Ajaccio (in southern Corsica) is 20165, meaning that the x-coordinate is 20 and the y-coordinate is 16. Postcodes are important for both postal services and businesses in Corsica. In addition to allowing businesses to keep track of their customers’ location, postcodes can also be used by individuals to quickly identify the area they are looking for and make sure they are getting the right package delivered to the right address.
