BSN
Citizen service number (BSN)
The citizen service number (BSN) is a unique personal number allocated to everyone registered in the Personal Records Database (BRP). Everyone who registers with the BRP is automatically given a BSN.
Using your BSN
The government uses your citizen service number (BSN) to process your personal data. You can use your BSN for any government service in the Netherlands. You do not have to provide your data to each different government organisation – they can find it using your BSN.
The BSN in healthcare
The citizen service number (BSN) allows you to identify yourself if you need care. Recognised care providers like general practice doctors and health insurance companies have to use the BSN.
The BSN in education
The BSN is also used in education, where it is called the personal identification number (PGN) or education number. The PGN is the same number as the BSN. Schools must use the PGN in their records.
The BSN for childcare benefit, housing benefit and healthcare benefit
Childcare organisations must ask for your and your child’s BSNs. The Benefits Office of the Tax and Customs Administration checks the number of childcare hours you report against the hours in the childcare organisation’s records. The same applies for landlords and the housing benefit, and healthcare insurers and the healthcare benefit.
Using the BSN to prevent identity fraud
The BSN’s main purpose is to help with contacts between different government organisations, and between individuals and government. Non-government organisations – like general practice doctors and other healthcare providers, pharmacies and healthcare insurers – can only use the BSN if the law requires it. The BSN makes it easier for government organisations to exchange personal details without making errors. Each organisation must make sure that you are using your own BSN.
The BSN (burgerservicenummer) social services number (or what was called the Sofi or Social-Fiscal number) is the first bureaucratic issue that expats in the Netherlands have to deal with.
What is the BSN / Sofi number?
A BSN (burgerservicenummer) is the citizen service number, a unique registration number for everyone who lives in the Netherlands.
The BSN will facilitate any interaction with the Dutch authorities: starting a job, opening a bank account, deducting your taxes and social security contributions, using the healthcare system, applying for benefits, announcing a change of address etc. It is also used to combat identity fraud and misspelled names.
The Sofi number (sofinummer) was the previous name for the social security number, issued by the Dutch Tax Office (Belastingdienst). From November 2007, those with Sofi numbers had them automatically converted into a BSN, and in January 2014, the Belastingdienst ceased issuing Sofi numbers.
Note that a BSN does not automatically allow expats to work in the Netherlands. Depending on their country of origin, they may need to apply for a work permit.
How to apply for a citizen service number?
You will receive your BSN when you register with the municipality (gemeente) of the area you will live in. Everyone who lives in the Netherlands, either for all or a significant part of the time, needs to register with their municipality within five days after arrival if they are planning to stay for more than four months.
When registering and thus receiving your BSN, EU citizens will need to provide a valid proof of identity (such as a passport, not a driving licence) and their address to be registered, while for non-EU expats other documents (such as your residence permit and employment contract etc.) have to be presented too.
For non-EU expats who are applying in the Netherlands for a residence permit, your registration with the municipality will be provisional. After you are registered, you will receive a letter of pre-registration (BvB) from the IND, which they will return to your municipality after you have applied for your residence permit. Then your registration and BSN will be confirmed.
What do you do if you have lost your BSN?
Lost your BSN number? No worries, you can find your number on a number of official documents, such as:
- Tax assessments or return letters sent to you by the Dutch Tax Office
- Your Dutch identity card / passport
- Your Dutch driving licence
If your identity document does not state your BSN number, simply go to the Dutch municipality where you are registered and request your BSN number there.
