BSN: This is why you really need one

April 10, 2026

What is a BSN and why do I need one?

BSN (previously called ‘SOFI number’) is an abbreviation for “burgerservicenummer”, which literally translates to “citizen service number”. It replaces the sofi number and tax number and acts as an all-round identification number for communication with the Dutch government. You need a BSN for a job in the Netherlands. With your BSN you can apply for a DigiD account, which allows you to apply for housing allowance, Healthcare allowanceextraterritorial tax credits and more.

How can I get a BSN and how much does it cost?

You get your BSN for free when you register with a Dutch municipality. You must register within 5 days of arriving in the Netherlands. Registration can be intimidating – especially if you do not know the Dutch language and customs. That is why we help our new employees by making a BSN appointment for them. We will even accompany you to the town hall if necessary!
