Hello,

Nice try but please do not do such a thing.

Postcodes and city names in Belgium are automatically obtained through existing areas and should not be added on addresses or POI; we are gradually phasing them out.  (And despite most people will talk about "Brussels" about any point within the Brussels-Capital Region, as long as OSM in concerned, the name solely applies to one of the municipalities and not the one here.  This is Schaerbeek - Schaarbeek).

Have a nice day.
