For the accuracy of statistics issued by the VBN or the auctions, a country code is linked to the country of origin of products supplied. The country code list should not be confused with the S62 list used for electronic messages. This list includes all country codes according to ISO directives. In practice, only part of this long list of codes is actually used. The country code list is administered for the auctions by the VBN. The ISO list is modified when new countries emerge and are assigned a new country code by the Netherlands Standardization Institute (NEN) or when there is a need on the part of the auction for a distinction not yet officially made by the NEN. In that case, a temporary code is created.
