Netherlands / 2013 74% open

As part of the "BAG" data which contains all addresses and buildings in the Netherlands. The data set is most likely public domain (In this http://geodata.nationaalgeoregister.nl/inspireadressen/atom/inspireadressen.xml the description link yields an XML that specifies public domain), and the national data portal lists the BAG as public domain (although provides faulty links) https://data.overheid.nl/data/dataset/basisregistratie-adressen-en-gebouwen-bag-. The downloaded data set does not contain licensing info.

Cadastre is the data holder but they provide no direct mention of the data set on their own site, just a reference to their paid for services. They are however listed as data holder and contact info in the links above as well.

The data dump is a 1.4 GB zip file, that contains 7 other zip files, yielding over 30GB of data when unpacked, split up in 21MB xml files. This is the full BAG data set, containing all addresses and buildings for all of the Netherlands. From this dataset you need to combine several subsets to get to a full postcode list: The ‘NUM’ files give you address index numbers, its georeferences, the house number and the postcode, and a number that corresponds with a street. The ‘OPR’ files give you the corresponding street name, and the number of the place it is in. The ‘WPL’ files give you the place name, and through a separate table also the municipality it is in. (Do note that is does not include postcodes that are not connected to geolocations, such as PO Boxes) See for a detailed description of the search for the Dutch postcode data; http://www.zylstra.org/blog/2013/10/theoretically-open-post-codes-not-so-much-in-practice/

The full data set is openly licensed (CC-BY), but only available on request, after which the (4GB) large file will be quickly made available for download. The OSM community is also hosting the dataset for download convenience at http://mirror.openstreetmap.nl/kadaster/

Although the data download page at data.overheid.nl states the date of the data set is Nov 2012, in reality if you download the XML file, it will have a generation date of today. The data is updated daily.
