Box 29 : Office of exit/entry

Use (an8) codes structured as follows:

  • the first two characters (a2) serve to identify the country by means of the country code entered in box 2,
  • 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 (a3) would be taken up by the UN/LOCODE 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 for the city of Brussels, 000 for the unused subdivision.
