First link provided contains maps of postal areas Postal codes can also be found at: QA question: Please explain how to obtain the data required for this item of the census according to the definition above. The file at contains postcodes and town/commune names, without geolocations in lat/long or equivalent. The link is to an inventory of maps, in shape files: how would these be used to obtain a table of postcodes and their lat/long please? Answer: The postcode information is available in multiple formats for different purposes. For polygons on maps (incl. lat/long), see here and here (text in Danish, maps in shape, mapinfo and geomedia). There's also a webservice from which you can enter an address and obtain the postcode. I'm not an expert in geodata myself so in order to answer the postcode-related questions at the Census I had help from (who might be more helpful in order to explain how to find the data of your need). Thanks to Andrew Stott and Neografen for help on this
