If you plan to live, work, or study in the Netherlands, you will need a BSN number. It is one of the most important identification numbers for residents.
What Is a BSN Number?
BSN stands for Burgerservicenummer, which means “Citizen Service Number.”
It is a unique personal identification number issued to anyone who registers in the Netherlands. The BSN is managed through the Dutch population register system and used by government authorities across the country.
It is required for almost all official and financial activities in the Netherlands.
What Does a BSN Number Look Like?
A BSN is a 9-digit number.
Example: 123456789
It:
-
Is unique to each person
-
Is permanent
-
Does not change during your lifetime
You receive it after registering your address at your local municipality.

You need it to:

Sign an employment contract

Pay taxes
-
Open a Dutch bank account

Register for health insurance
-
Visit a doctor or hospital

Apply for social benefits

Both EU and non-EU citizens must obtain a BSN if they reside in the country.
How to Get a BSN Number
You receive your BSN when you register at your local municipality (Gemeente).
Step 1: Register Your Address
Within 5 days of moving to the Netherlands, you must register at the municipality where you live.
For example:
-
If you move to Amsterdam, you register at the Amsterdam municipality.
-
If you live in Rotterdam, you register at the Rotterdam municipality office.
Step 2: Provide Required Documents
You usually need:
-
Valid passport or EU ID card
-
Rental contract or proof of address
-
Birth certificate (sometimes required)
-
Residence permit (for non-EU nationals)
After registration, your BSN is issued immediately or sent by post within a few days.
What If You Stay Less Than 4 Months?
If you plan to stay less than 4 months, you can register in the Non-Residents Register (RNI).
You will still receive a BSN, which allows you to:
-
Work temporarily
-
Pay taxes
-
Receive salary
However, you must register fully if you stay longer than 4 months.
Is BSN the Same as a Residence Permit?
No.
-
BSN → Personal identification number
-
Residence permit → Legal document allowing you to stay
Residence permits are issued by the Immigration and Naturalisation Service (IND).
The BSN is issued by the municipality after registration.
Is BSN Mandatory for Work in the Netherlands?
Yes.
Employers need your BSN to:
-
Register you with Dutch tax authorities
-
Process payroll
-
Deduct income tax
-
Register social security contributions
Without a BSN, you cannot legally work.
Does a BSN Expire?
No.
Your BSN is permanent and valid for life.
Even if you leave the Netherlands and return later, your BSN remains the same.
Can You Open a Bank Account Without BSN?
In most cases, no.
Dutch banks require a BSN to:
-
Open a current account
-
Receive salary payments
-
Apply for financial services
