If you are moving to the Netherlands to study or work, the BSN number is one of the first things you will need to sort out, often before your bank account, your health insurance, or even your first payslip. Without it, almost nothing else on this list works.
BSN stands for Burgerservicenummer, or citizen service number. It is a unique, personal eight- or nine-digit number that the Dutch government uses to identify you across healthcare, tax, education, and benefits, the closest Dutch equivalent to a Social Security Number in the United States. This guide covers what it is, why you need one, how to apply, where to find it once you have it, and when you eventually have to deregister.

The BSN is a unique, personal number assigned to almost everyone who lives in, works in, or has significant dealings with the Netherlands. Every municipality records residents' BSN and personal details in the Basisregistratie Personen (BRP), the Dutch personal records database, according to the Dutch government's official BSN page.
The BRP holds more than just your number. It typically includes your full name, date of birth, nationality and immigration status, your registered address, and, where relevant, details about your parents, partner, or children. Municipalities, the tax authority, healthcare insurers, and other public bodies all draw on the same BRP record instead of keeping separate files, which is why the same nine digits follow you through nearly every official interaction in the country.
Technically, it is possible to live in the Netherlands for a short stretch without ever registering for a BSN. In practice, almost every administrative and financial task you will need to complete runs through it, so putting it off just creates friction later. Here is where it comes up:
Applying for a BSN is one of the first practical tasks on your list once you arrive, and the route depends on how long you are staying and where you are coming from. If you are not sure which of the routes below applies to you, a free prompt can narrow it down from your nationality, your arrival date and how long you are staying.
Most new residents get their BSN by registering in person at their local gemeente (municipality). Anyone planning to stay in the Netherlands for more than four months is expected to register within five days of arrival; the municipality then assigns a BSN as part of that registration.
The documents required differ slightly by citizenship:
Having your BSN in hand is also the trigger for other applications; once you are registered, you can move on to things like Dutch student finance, since DUO requires a BSN on file before it will process a grant or loan application.
If you live outside the Netherlands, or you are coming for less than four months to study or work, you can still get a BSN by registering in the Non-residents Records Database, known as the RNI. This is done in person at one of a limited number of municipalities that run an RNI desk, not at every gemeente.
If you live abroad and want to claim the Dutch state pension (AOW), the Sociale Verzekeringsbank (SVB) can register you in the RNI and issue a BSN as part of that process. Separately, if you need a BSN purely for inheritance tax purposes, you can apply for one directly through the Belastingdienst, the Dutch tax authority.
Once you have a BSN, you do not need to memorise it; it is printed on most of the official documents you already carry.
If none of those are available, you can visit the municipality where you are registered and request confirmation of your BSN in person.
International students juggling rent alongside all of this should also look at what housing benefit and other allowances you may be able to claim once you are registered.
Once your BSN comes through, applying for a DigiD is usually the next step, since it is the login you will use for almost every online interaction with Dutch authorities, from filing taxes to applying for healthcare benefits.
To apply:
Your BSN itself does not expire and stays valid for life, even if you later leave the Netherlands; you can reuse it if you return or need to claim benefits from abroad. It is retired only after death.
Your BSN is also the number the Belastingdienst uses to track your income tax and, if relevant, VAT filings once you start working or freelancing. Our complete guide to Dutch taxes covers the filing process in more detail once you have a payslip or invoices coming in.
Deregistering matters just as much as registering, and it is easy to overlook when you are focused on packing:
Skipping this step can leave you registered as a resident when you are not, which complicates tax filings and future re-entry.
Turning that checklist into your own dated to-do list takes a couple of minutes: our free prompt runs in ChatGPT, Claude or Gemini and will list the documents you personally need to bring to the appointment. - Keep your BSN handy for healthcare, banking, tax, and benefit applications; it appears on your passport, ID card, driving licence, and insurance card. - Moving away for good, or for more than eight months? Deregister with your municipality at least five days before you leave.
The BSN number is not optional admin you can put off; it is the number that everything else in the Netherlands, from your bank account to your health insurance to your first payslip, is built around. Register as early as you can, whether that is at your local gemeente or through the RNI, and the rest of your paperwork tends to fall into place faster. College Life keeps supporting you well past this first step, with more guides and a community of internationals working through the same admin.

What is a BSN number in the Netherlands? BSN stands for Burgerservicenummer, or citizen service number. It is a unique eight- or nine-digit number the Dutch government assigns to residents to identify them across healthcare, tax, education, employment, and benefits.
How do I apply for a BSN number? Register at your local municipality if you are staying more than four months, or through the RNI (Non-residents Records Database) if you are staying under four months or applying from abroad. EU citizens need a passport or ID card and proof of address; non-EU citizens generally need a residence permit application on file.
Where can I find my BSN number? It is printed on your Dutch passport, Dutch identity card, driving licence, and health insurance card, and it is visible in the "Identiteit" section of MijnOverheid once you log in with your DigiD.
Do I need a BSN before I can get a DigiD? Yes. A BSN is required to start a DigiD application, since DigiD is the login used for almost every online interaction with Dutch government services.
When do I need to deregister my BSN? Deregister with your municipality if you are moving abroad or expect to spend more than eight months outside the Netherlands in a year, no later than five days before you leave. Moving to a new address within the Netherlands does not require deregistering; your new municipality handles the update automatically.
