Registering, moving
or leaving your address
Address registration works differently in Belgium than in many other countries, and it is not just a formality you complete once and forget. The process follows the same basic pattern whether you are registering for the first time, moving within Belgium, or leaving for good.
This page walks you through what to do in each of these three situations.
Overview
Every time your address changes, whether you are arriving, relocating within Belgium or leaving the country, you need to report it to your municipality (gemeente). This keeps the national population register accurate, and it directly affects your residence permit, your taxes and your access to services, so it is not something to leave until later.
Registering for the first time
When you arrive in Belgium with the intention of staying, you must register at the municipality covering your new address within 8 days. This is the step that officially adds you to the population register, and it is a strict legal requirement, not just an administrative formality.
To register, you will generally need the documents covered in Required documents. In most cases that means your passport (and visa or residence document, if applicable) and proof that you live at the address you are registering, such as a rental contract or a declaration from your landlord or host. Your municipality can confirm exactly what it asks for. In some municipalities, a local police officer may visit your address afterwards to confirm you live there before your registration is finalised, so it helps to make sure your name is visible on the doorbell or mailbox.
Once your registration is processed, you will receive confirmation and, in time, a residence permit or Belgian identity document tied to your situation.
Moving to a different municipality
if you relocate to a different municipality within Belgium, you need to report your change of address to your new municipality within 8 working days of moving - many municipalities also let you do this online. You do not need to deregister at your old municipality; your file transfers automatically.
After you report the move, a local police officer (wijkagent) will visit your new address to confirm you actually live there. Once that check is complete, your new address is officially registered and you update the address on your ID or residence card at the town hall. The documents needed are usually your identity document and your residence permit if you have one.
Moving away from Belgium
If you are leaving Belgium for good, you also need to report your departure, rather than simply letting your registration lapse. You report it to your municipality shortly before you leave, and you receive a certificate of deregistration (Model 8) - so that you are properly removed from the population register.
Reporting your departure matters for practical reasons too. It affects your tax situation, closes off obligations tied to your Belgian address, and avoids complications if you ever want to move back or register elsewhere in the EU. Some municipalities, such as Ghent, publish their own step-by-step guidance on reporting a departure, so it is worth checking your own municipality's website for the exact process.
Good to know: the 8-day deadline applies whether you are registering, moving, or in some cases deregistering, so mark it in your calendar as soon as you know your move date. Missing it will not usually cause immediate problems, but it can complicate things like your residence permit renewal or tax filing later on.
