The BSN (burgerservicenummer) is a unique citizen service number in the Netherlands, essential for residents and taxpayers. It is comparable to a Social Security Number (SSN) in the U.S. or a Tax Identification Number (TIN) in other countries. A BSN is assigned to anyone registering in the Dutch municipal records database (BRP) or the Non-Resident Records Database (RNI), including non-residents staying in the Netherlands for more than four months.

It simplifies communication with government agencies, healthcare providers, and employers, serving as a vital identifier for accessing public and private services.

Getting your BSN

To obtain a BSN, you need to register at your local municipality (gemeente) or an expat center, such as IN Amsterdam. Registration requires an appointment, which can be booked online or by phone. Document requirements may vary, so check with the municipality in advance.

Generally, you’ll need the following:

• A valid passport.
• Birth certificate (apostilled, translated, and with the original copy).
• Proof of residence (e.g., rental contract, landlord consent, hotel agreement, or property ownership documents).
• Residence permit card or a confirmation letter from IND.
• If applicable, a marriage certificate (apostilled, translated, and with the original copy).

Once registered, your BSN is either issued immediately or sent by post within 2–3 weeks. This number remains valid for life, even if you leave the Netherlands and return later.

Why do you need it?

The BSN is central to your integration into Dutch society. It’s required for:

• Starting employment: Employers need your BSN to correctly calculate taxes and register you as an employee.
• Opening a bank account: Most banks require a BSN for account setup, although some allow temporary accounts without one, provided you supply it within 90 days.
• Accessing healthcare: Healthcare providers and insurers use your BSN to ensure accurate billing and services.
• Filing taxes: The tax authority uses your BSN to identify you as a taxpayer, ensuring proper deductions and benefits like the 30% ruling.
• Enrolling in education: Schools and universities use the BSN to manage student records and registrations.

If you need to open a bank account or start work before receiving your BSN, ask your municipality for a temporary proof of registration. This can help you navigate initial hurdles while waiting for the BSN to arrive.

Where can you find it?

Once issued, your BSN appears on various official documents and platforms, including:

• Your Dutch driver’s license.
• Letters from the tax office.
• Your health insurance card or policy.
• The Mijn Overheid portal (accessible with DigiD).

If you lose track of your BSN, contact your local municipality for assistance.
