What is the BSN?
The BSN (Burgerservicenummer) is a unique 9-digit identification number assigned to everyone registered in the Netherlands.
You need a BSN to:
Open a Dutch bank account
Apply for zorgtoeslag (up to 123 euros/month)
File a Dutch tax return
Sign an employment contract
Who needs to register?
Gemeente registration: If staying 4+ months with a fixed address, register at your local gemeente.
RNI registration: If staying less than 4 months or without a fixed address, register at one of the 19 RNI municipalities — you get your BSN the same day.
What documents do you need?
| Document | EU citizens | Non-EU citizens |
|---|---|---|
| Valid passport or EU ID | yes | yes |
| Proof of Dutch address | yes | yes |
| Residence permit | Not needed | yes |
How long does it take?
RNI: Immediate — same day
Gemeente: 3-5 working days
What happens after?
