The BSN is a nine-digit number issued by the Dutch state, and almost nothing in this country works until you have one.
It is the key to a salary, a bank account, health insurance, a GP, and every online government service.
You do not apply for it directly.
It arrives as a by-product of registering yourself, and there are two different ways to register.
The two doors
Which door you use depends on one question: are you staying four months or longer?
If you are, you register in the Basisregistratie Personen, the population register, at the gemeente where you live.
Everyone entered in the BRP is given a BSN automatically.
That is the normal route for anyone moving here, and the appointment itself is a separate business with its own document list and its own waiting time.
If you are staying under four months, or you live abroad and need a Dutch number for a specific reason, you use the Registratie Niet-Ingezetenen instead.
The RNI is the non-residents register.
It gives you a BSN and nothing else: no address record, no municipal services.
The RNI counter in The Hague
The Hague runs one of nineteen RNI counters in the country.
It sits at the gemeente and opens Monday, Tuesday and Thursday from 8.30 to 16.30.
Registration is free, and the gemeente’s own wording is that you are entered in the RNI on the spot and walk out with your BSN the same day.
You need a valid passport or identity card, and a QR code produced by the national online form at rni-webform.rvig.nl.
Fill that in before you come.
For a child under 16 you also bring the birth certificate, any deed of recognition, and both parents’ identity documents.
One rule changed at the start of this year and it catches people out.
Since 1 January 2026, gemeente Den Haag only registers non-residents holding a European passport. If your passport is not European, the RNI desks in Breda and Venlo handle you instead.
The nineteen counters are not interchangeable any more, and turning up at Spui with the wrong passport means a train journey you did not plan.
What stops without one
The list is longer than most people expect, and it is circular in places.
Your employer cannot run payroll without it, so a job offer can be signed and still produce no money.
A Dutch bank account needs it.
Health insurance needs it, and health insurance is compulsory within four months of arriving, so the clock is already running while you wait for an appointment.
A GP will not take you on without it.
Neither will a pharmacy fill a prescription against your insurance.
Childcare and schools use it to register a pupil.
Benefits and allowances are calculated against it.
And DigiD, the login that the entire Dutch internet assumes you have, cannot be issued at all without a BSN and a registered address.
That is the dependency that turns one missed appointment into a month of being unable to do anything online.
Who is allowed to ask for it
Government bodies may use your BSN freely.
Everyone else may only use it where a law specifically permits it.
In practice that covers your employer, your health insurer, your GP, your pharmacy, your child’s school and your childcare provider.
It does not cover every organisation that would find it convenient.
If a company asks for your BSN and you cannot see why it needs one, the reasonable question is which law requires it.
Estate agents and letting platforms are the usual place this comes up, and it is worth knowing that a request for identity documents early in a rental process is a recognised pattern.
Getting the appointment
Appointment availability is the real constraint on all of this, not the paperwork.
Book before you have finished unpacking.
Some arrivals get a faster route.
If you work for an employer that is a recognised IND sponsor, an international organisation, an embassy, an NGO, a university or a knowledge institution, and you live in The Hague, Delft, Rijswijk or Leidschendam-Voorburg, you register through The Hague International Centre rather than the ordinary municipal queue.
It is the same registration and the same BSN, handled at a different desk.
Everyone else uses the gemeente.
If your stay depends on a residence permit from the IND, bring the permit or the IND’s letter of approval to the registration appointment, because the two systems check each other.
The number itself never changes and never expires.
You keep the same BSN if you move house, change jobs, leave the country and come back.
Write it down somewhere you will find it, because you will be asked for it more often than for your own address.
Advisers who do this for a living, including relocation and immigration services in The Hague, can book and attend the appointment with you, though for a straightforward BRP registration there is genuinely nothing to buy.
