Registration & BSN in the Netherlands
If you've just moved to the Netherlands, you're going to hear three letters very quickly: BSN.
Your employer may ask for it. The government needs it. You'll come across it when arranging healthcare, taxes and DigiD. Basically, if you're planning to build a life in the Netherlands, your BSN is one of the first important things to sort out.
The process sounds more complicated than it actually is. The main thing you need to know is that your BSN and your registration are connected.
So, What Exactly Is a BSN?
BSN stands for Burgerservicenummer, or citizen service number. It's your unique personal number in the Dutch system.
You'll use your BSN when dealing with Dutch government organisations and for things such as taxes, health insurance and applying for DigiD. A BSN consists of eight or nine digits.
And here's something worth knowing: you only get one BSN. If you leave the Netherlands and come back several years later, you don't apply for a brand-new number. Your existing BSN remains yours.
So if you've lived, worked or studied in the Netherlands before, check whether you already have one before trying to register for another.
Staying for More Than Four Months? Register With Your Municipality
If you're moving to the Netherlands and expect to live here for more than four months, you need to register as a resident with the municipality — the gemeente — where you're going to live.
Officially, this should be done within five days of arriving in the Netherlands.
In reality, it's a good idea to look at your municipality's website before you even arrive and see whether you can book an appointment. Waiting times can vary, and you don't want to arrive and discover that the next available appointment is much later than expected.
When you register, your details are entered into the BRP, which stands for Basisregistratie Personen — the Personal Records Database.
If you don't already have a BSN, you'll receive one as part of this registration.
So you don't normally need two separate appointments — one to “register” and another to “get a BSN”. For someone moving to the Netherlands as a resident, the BSN generally comes through the registration process.
What Should You Bring?
This is where we strongly recommend checking the website of your own municipality.
Don't rely entirely on a colleague telling you, “I only needed my passport.” Their situation might be completely different from yours.
You'll obviously need valid identification, such as your passport or identity card. Depending on your personal situation, the municipality may also ask for documents such as a birth certificate or marriage certificate.
Foreign documents may sometimes need to be translated or legalised.
If you're moving with your partner or children, remember that they need to be registered too. Family members moving to the Netherlands with you generally need to appear in person for registration as well.
Our advice? Check the municipality's requirements before leaving your home country. It's much easier to bring the correct original documents with you than to discover after arriving that the certificate you need is sitting in a drawer back home.
Your Address Matters
When registering as a resident, you'll normally register at the address where you actually live.
This is one reason we keep mentioning registration possible in our housing guides.
When you're searching for a room or apartment, don't be afraid to ask the landlord or agency:
“Can I register at this address?”
If someone tells you that you can live there but absolutely cannot register there, find out why before handing over money.
Your registered address becomes part of your BRP information, so this isn't just an unimportant piece of administration.
If your living situation is unusual and you don't have a normal permanent home address, there are situations where a correspondence address may be possible. That's something to discuss directly with the municipality because specific conditions apply.
Staying for Less Than Four Months? That's Different
This is where newcomers often get confused.
If you're coming to the Netherlands for less than four months — perhaps for temporary work, a short study period or an internship — you normally don't register as a resident in the same way.
Instead, you can register in the RNI, the Non-residents Records Database.
The RNI is part of the wider BRP system and is intended for people who don't live in the Netherlands or who will be here for less than four months.
You register in person at an RNI desk. There are designated municipalities in the Netherlands that provide this service.
After RNI registration, you'll receive a BSN.
So yes, you can have a BSN without being registered as a Dutch resident.
That's an important distinction.
More than four months: usually register as a resident with the municipality where you live.
Less than four months: RNI registration may apply.
BRP, RNI, BSN... Why So Many Letters?
Welcome to Dutch administration.
It sounds confusing at first, so here's the simple version.
BRP is the Personal Records Database.
If you live in the Netherlands, you're normally registered there as a resident through your municipality.
RNI is the non-resident part of that system. It's for people who live abroad or are staying in the Netherlands for less than four months.
BSN is your personal citizen service number.
So BRP and RNI are about how you're registered. Your BSN is your personal number.
Once you understand that difference, the whole thing becomes much less mysterious.
What Do You Actually Need a BSN For?
Your BSN will follow you through a lot of Dutch administration.
You'll need it when dealing with government organisations, and it is used for things such as taxes, healthcare and pensions. You also need a BSN before you can apply for DigiD, your digital login for many Dutch government services.
Employers will also need certain personal information to process your employment and payroll correctly, which is another reason newcomers often hear “Do you have your BSN?” almost immediately after arriving.
Don't post your BSN publicly or casually share it with random people. It's personal information and should be treated that way.
I Already Had a BSN Years Ago. Do I Need Another One?
No.
Your BSN doesn't expire simply because you've moved away from the Netherlands.
If you worked here five years ago, went home and have now decided to come back, you should still have the same BSN.
If you can't remember it, don't panic. There are ways to check whether you're already registered and find your existing number.
The important thing is don't assume you need a new BSN every time you come back to the Netherlands.
Can I Get a BSN Before Finding a Permanent Home?
This depends on your situation.
If you're genuinely moving to the Netherlands for more than four months, resident registration is normally connected to the municipality where you're living. If you're staying for less than four months, RNI registration works differently and uses your address abroad.
Don't simply choose RNI because it seems like a quicker way to get a BSN if you're actually moving to the Netherlands permanently. Your registration should reflect your real situation.
If you're struggling with housing or don't have a standard residential address, speak to the municipality and explain your circumstances. They'll be able to tell you which registration option applies.
What Happens After Registration?
Once you've registered and received your BSN, you've completed one of the most important pieces of Dutch administration.
Next on your list should usually be DigiD.
DigiD is your digital identity for accessing many government services online. You'll eventually use it for all sorts of things, so it's worth arranging fairly soon after registration.
After that, you can continue getting the rest of your Dutch life organised — health insurance where required, banking, GP registration, taxes and everything else that comes with settling in.
A Few Tips From Us
Book your appointment early. Don't wait until you've already arrived if your municipality allows you to arrange an appointment beforehand.
Check the documents yourself. Your friend, recruiter, employer or landlord may be trying to help, but the municipality is the one actually registering you.
Bring original documents when required. A photo of your birth certificate sitting on your mother's kitchen table isn't quite as useful when the municipality wants the actual document.
Ask whether registration is possible before renting. This can save you a major headache later.
Keep your BSN private. Give it to legitimate organisations when necessary, but don't treat it like your Instagram username.
And finally, don't worry if all of this sounds confusing before you arrive. After you've done it once, it's actually pretty straightforward.
Register with the right authority, get your BSN, arrange your DigiD and move on to the more interesting parts of living in the Netherlands.
Preferably something involving coffee and a stroopwafel.
