Postcodes / Zipcodes / 2013 45% open

What data is expected?

A database of postcodes/zipcodes and the corresponding geospatial locations in terms of a latitude and a longitude (or similar co-ordinates in an openly published national co-ordinate system). A database which gives a location in terms of the name of a town or a street without lat/long co-ordinates is not considered acceptable unless the name of the town or street can be further converted to a latitude and longitude by means of other open data (eg an open gazetteer with latitude and longitude attributes).

Details

The data is still not officially available as Open Data. The site http://adressesok.posten.no/en/postal_codes/search?q=1350 allows web queries postcode lookup to get the name of the locality. This is HTML only with a restrictive licence at http://adressesok.posten.no/en/pages/usage_terms and only one postcode can be queried at a time Once the locality is known, the geospatial dataset http://data.kartverket.no/download/content/stedsnavn-ssr-wgs84-geojson could be used to obtain a rough lat/long of the postcode. However, as suggested by the original submitter, it's been gathered and made available by a private citizen, at http://www.erikbolstad.no/geo/noreg/postnummer/. However, the privately gathered data is has some quality/accuracy issues, so it's a good question as to whether it can be considered complete.
