What is a citizen service number (BSN)?
The citizen service number (BSN) is a unique number for everyone who has dealings with the Dutch government. You can and must use the citizen service number increasingly often, in dealings with your municipality, the hospital, schools, your employer or benefits agencies, for example. With the citizen service number, the Dutch government wants to improve the services it provides to you, combat fraud and improve protection of your privacy.
All information about the citizen service number can be found at www.burgerservicenummer.nl (only available in Dutch), for example information about which government authorities exchange information on the basis of citizen service numbers.
You can also contact the BSN-point via telephone number 1400. The BSN-point is part of the Public Information Service (only available in Dutch).
