# Commission Implementing Regulation (EU) 2015/2447 of 24 November 2015 laying down detailed rules for implementing certain provisions of Regulation (EU) No 952/2013 of the European Parliament and of the Council laying down the Union Customs Code, Division 1/7: Decision taking customs authority


The structure of the codes is the following:
the first two characters (a2) serve to identify the country by means of the country code as defined in Commission Regulation (EU) No 1106/2012,
the next six characters (an6) stand for the office concerned in that country. It is suggested that the following structure be adopted:
The first three characters (an3) would be taken up by the UN/LOCODE location name and the last three by a national alphanumeric subdivision (an3). If this subdivision is not used, the characters ‘000’ should be inserted.
Example: BEBRU000: BE = ISO 3166 for Belgium, BRU = UN/LOCODE location name for the city of Brussels, 000 for the unused subdivision.
