Social Security Number (BSN)
The Burgerservicenummer (BSN) is a unique personal number in the Netherlands. Anyone who is registered in the Municipal Personal Records Database (BRP) will receive a BSN. This occurs at birth and immigration.
After immigration, the municipality can register you in the BRP once they have received permission from the Immigration and Naturalization Service (IND), and you have a valid residence permit. This may take up to 2 months. The day after enrollment in the BRP other government agencies (such as child support, tax authorities) will receive your new data.
Seasonal workers who will stay in the Netherlands for only a couple of months can receive a BSN at the RNI-desk (Registration for non-residents of the Netherlands) at the cities of Breda and Eindhoven. Make an appointment through www.breda.nl or www.eindhoven.nl or by calling 14 076 or 14 040. Registration in the municipality (BRP) is not necessary.
