postal_code and addr:postcode taken from either nodes or ways -- they all get turned into points then it creates a giant voronoi diagram and pieces together polygons from continuous cells. There's lots of streets tagged postal_code in the UK (mostly with just the prefix from a street sign) and then recently there's lots of buildings and points tagged with addr:postcode so those are included too. There are layers for data from the NPE and FTP projects too. Last updated in May.
