What is a citizen service number?

A citizen service number (BSN) is the unique personal number you are registered under in the Personal Records Database (BRP). A BSN is comprised of 8 or 9 digits.

What do I need a BSN for?

You use your citizen service number if you want to arrange something with the Dutch government. For example, your health insurance, your tax return or your pension. You also need a citizen service number if you want to apply for a DigiD.

Period of validity

You receive a citizen service number once. Your citizen service number will always remain valid and unchanged. Even if you live abroad (or are going to live abroad). Or if you return to the Netherlands from abroad.

Replacement for tax and social insurance number

The citizen service number has replaced the tax and social insurance number (sofinummer).

Please note: if you left the Netherlands before 1 October 1994, you may no longer be able to use your tax and social insurance number as your BSN. Contact a RNI municipality for more information.

Do I have a BSN?

You have a citizen service number if you are registered in the Personal Records Database (BRP) or the Non-residents Records Database (RNI). Not sure whether you have a citizen service number? Read where you can find your BSN.
