A (vector) map of Spain’s Postal Codes can only be obtained if it is purchased from Spain’s National Postal Service (Correos) at an abusive price given the fact that it is reference information generated with public resources.This paper makes up for this lack of free resources, by offering information on how to access geocoded addresses published by Cartociudad and available at the Download Center section of the National Center for Geographic information (CNIG).The paper describes the algorithm to elaborate the vector layer of Postal Codes, implemented in the free software, R. Additionally, it describes the availability of information on Spain’s Postal Codes and reports some anomalies found in the base information used.
