BRP and RNI registration for international workers in the Netherlands

Before an international worker can be paid correctly, taxed properly and legally housed in the Netherlands, they usually need a number. BRP and RNI registration for international workers in the Netherlands is the process that issues it — the burgerservicenummer, or BSN — and getting it wrong is one of the most common reasons a mobilisation stalls in week one. This guide explains the two registers, when each applies, and how accommodation fits into the picture.

The difference comes down to how long the worker stays. Anyone intending to live in the Netherlands for more than four months in any six-month period registers in the BRP (Basisregistratie Personen) at the municipality where they actually live — which means they need a genuine residential address. Workers staying less than four months register instead in the RNI (Registratie Niet-Ingezetenen), the non-residents register, at one of the designated RNI municipalities such as Amsterdam, Rotterdam, Utrecht or Eindhoven. Both routes issue a BSN; the RNI route simply does not tie it to a home address.

Why BRP and RNI registration for international workers in the Netherlands depends on the address

This is where housing and registration collide. A BRP registration requires proof that the worker can live at the address, and many private landlords refuse to allow it — which leaves the worker unable to register, unable to open a bank account, and sometimes unable to be paid. Managed, permitted worker accommodation solves this because the property is set up to allow occupant registration from the outset. When we place a crew, BRP registration at the address is part of the arrangement, not an obstacle the worker discovers later. See how we keep housing audit-ready in our approach to compliance.

For short-stay crews the RNI route is faster: the worker books an appointment at an RNI desk, brings a valid passport or ID and, ideally, a document showing the reason for the stay, and walks out with a BSN the same day. There is no address requirement, which suits turnarounds and short project phases. The catch is that a BSN alone does not make housing compliant — the accommodation still needs the correct permits regardless of which register the occupant used.

For employers and staffing agencies the practical lesson is that registration is not purely the worker's problem. Payroll, the 30% ruling where it applies, health insurance and the correct handling of the posted-worker notification all hang off a valid BSN. A crew that cannot register is a crew that cannot be paid cleanly, and that friction lands back on the employer. Building registration into the housing plan from day one removes it as a risk.

In practice we treat registration as part of the accommodation product. Whether you need labour and manpower accommodation for a large agency placement or compliant worker housing for a long-running project, the address is registration-ready and the paperwork is kept in order so a payroll or client audit passes cleanly.

If you are mobilising an international crew and are not sure whether they need BRP or RNI, tell us the headcount, the nationalities and the expected length of stay and we will match housing that supports the right registration route.
