Did you know?

You can check Belgian postcodes on our

Name of box recipient + PO Box + postcode + municipality + post office name.



Three important basic rules:

  • Do not mention "Belgium" if you write a domestic mail
  • Do not use the ISO country code (e.g. FR-, D, CH, etc.). These elements are not used by our machines but can cause errors in the sorting and distribution of the post
  • For any international mail, you must write the country of destination


The name of the country of destination must always be written:

  • On the last line of the address
  • In full and in capitals
  • Without underlining
  • In one of the national languages or in English
