Declaration to the Administration (registration)

Persons possessing Belgian nationality (or foreigners with a number of the National Register) can declare the change of address on Irisbox

Population Service – Tel : 02/773.05.47 of 02/773.05.49 (foreigners)


Every person of Belgian or foreign nationality who chooses to reside mainly on the territory of the municipality, must register himself and all members of the household in the population- or foreigners register. This declaration needs to take place within 8 working days at the Population Service.

In case the modification of address concerns all household members, one member is sufficient to register all members at once.

To make your registration effective, a neighbourhood inquiry will be carried out to check if you are well domiciled at the address you have declared.
