BSN in the Netherlands: How International Students Register and Why It Matters
TL;DR: How do international students get a BSN in the Netherlands? The citizen service number (BSN) is given automatically when you register in the Personal Records Database (BRP) at your municipality. If you will stay longer than 4 months, you must register in person within 5 days of arrival, usually by appointment, with your passport, proof of lawful residence and proof of address. You need the BSN to open a bank account, take out health insurance, work and apply for DigiD.
The BSN in the Netherlands is the number almost every system asks for in your first weeks. Without it, opening a bank account, starting a part-time job or registering with a GP becomes difficult, so registration belongs on your arrival checklist, not after it.
This guide covers what the BSN is, who must register, what to bring and what to do next. If you are applying from Sri Lanka, the local points are near the end.

What is a BSN?
The Dutch government describes the BSN as a unique personal number allocated to everyone registered in the Personal Records Database. It has 8 or 9 digits, and everyone who registers in the BRP is given one automatically. Government bodies, health insurers and GPs use it to identify you.
Who must register, and how fast?
- Staying longer than 4 months. You must register with your municipality in person within 5 days of arrival. In most cases you need an appointment, so book as soon as you know your address.
- Staying 4 months or less. You can register in the Non-residents Records Database (RNI) at one of 19 municipalities with an RNI desk. Everyone in the RNI also has a BSN.
- Residence permit first. Rotterdam, for example, registers you only once you hold a residence permit or have an application in progress.
Some municipalities, such as Rotterdam and Utrecht, describe the threshold as staying at least 4 of the next 6 months. Check your own municipality's page.
What if there is no appointment within 5 days?
Book the first slot you can and keep the confirmation. The Hague, for example, says registration can be backdated to the date you booked the appointment. Book as soon as you have a confirmed address.
What should you bring to the appointment?
| Document | Why it is needed |
|---|---|
| Valid passport | Proof of identity |
| Proof of lawful residence | Your residence permit, MVV sticker or IND letter inviting you to collect your permit |
| Proof of address | A rental contract or a declaration from the main occupant |
| Birth certificate, if asked | Some municipalities, such as Utrecht, ask for original civil certificates; others, such as The Hague, do not require them |
Utrecht accepts documents in English, German or French without translation; other languages need a certified translation. Study in NL notes that a municipality can refuse registration only if you have no valid passport, no lawful residence or are staying 4 months or less.

What do you need the BSN for?
- Bank account. Study in NL lists the BSN as needed to open a bank account.
- Work and internships. Employers need it to pay you. If you take a part-time job, you must also take out Dutch public health insurance. See our guide to Netherlands student work hours.
- Health care. GPs and insurers must use your BSN. Our guide to health insurance for international students in the Netherlands explains which cover you need.
- DigiD. You need a BSN, a registered address and a mobile phone to apply. The activation code arrives by post.
How does registration fit with your residence permit?
Your university applies for your residence permit, and the IND invites you to collect it once it is ready. Many universities also run registration days for new students, which can make the municipality appointment easier. Our guide to the Netherlands student residence permit explains the steps before you arrive.
Applying from Sri Lanka
- Sri Lanka is not on the Dutch list of apostille countries. Sri Lankan documents are legalised digitally through the Sri Lankan Ministry of Foreign Affairs before use in the Netherlands.
- Netherlands Worldwide says documents in Sinhala or Tamil need a sworn translation into Dutch, English, French or German, while English-language documents need none.
- If your municipality asks for a birth certificate, arrange the legalised version and any translation before you leave.
Frequently asked questions

The number is issued when you are registered at your municipality appointment. Book the appointment early, because you must register within 5 days of arrival.
Can I get a BSN before I arrive?
Students staying longer than 4 months register in person after arrival. Shorter stays can use an RNI desk.
Do I need a BSN to open a Dutch bank account?
Yes, banks ask for it, so register before you try to open an account.
PS: Before you fly, put your passport, IND letter, rental contract and any legalised certificates in one folder. If you would like help planning your Netherlands application, Check your eligibility with Prosper.
