Postcodes / Zipcodes 0% 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).

You can search for a postal code : http://www.elta.gr/en-us/findapostcode.aspx But that does not give you the corresponding geospatial location of that postal code. Unsure if that data exists.
