I moved — how and where do I register my new address?

Direct answer

Registering your address is compulsory within a short deadline after moving (days to weeks, depending on the country) and everything official flows from it: the ID number, tax, voting, health insurance, school places. Register at Dienst Bevolking van de gemeente / Mijn Burgerprofiel (belgium.be) — online with a digital ID in many countries, otherwise at Gemeentebestuur / stadsbestuur (belgium.be) — with ID and proof of the new address (rental contract, deed, or the landlord's or host's declaration). FOD Financiën — bezwaar / MyMinfin (02 572 57 57) and the other agencies are informed automatically in most countries — but check your tax and benefit accounts after a few weeks.

❓ Frequently asked

The landlord will not give me a declaration

Most countries let you register with the rental contract alone; if the landlord obstructs, Gemeentebestuur / stadsbestuur can register you on other evidence and the landlord may be fined.

Can I register in a friend's flat?

Yes, if you actually live there — with the friend's declaration. It can affect their benefits or taxes; tell them.

I have no fixed address

Municipalities offer a postal address for homeless residents so that benefits and documents work. Ask Gemeentebestuur / stadsbestuur or social services.
