BSN Number in the Netherlands: How to Get One for Americans
Your BSN number is the single most important number you will receive in the Netherlands. Without it, you cannot open a bank account, get health insurance, start your business, or do almost anything official.
The good news: getting your BSN is straightforward. It happens automatically when you register at the gemeente (municipality). Here is everything you need to know about the process as someone moving on the Dutch-American Friendship Treaty (DAFT) visa.
What Is a BSN Number?
BSN stands for burgerservicenummer, which translates to "citizen service number." It is a unique nine-digit number assigned to everyone registered in the Netherlands.
Think of it as the Dutch equivalent of a Social Security number. You will use it for:
- Health insurance registration
- Opening a Dutch bank account
- Tax filings and dealings with the Belastingdienst
- Registering your business at the KVK (Chamber of Commerce)
- Setting up your DigiD (digital identity)
- Government correspondence
- Employment and social services
Unlike the US, where you can sometimes get by without your SSN, the Dutch system runs entirely on BSN numbers. Every interaction with the government, healthcare system, or financial institutions requires it.
How to Get Your BSN
You get your BSN by registering at the gemeente. This is one of the first things you should do after arriving in the Netherlands.
Step 1: Make an Appointment
Contact the gemeente in the city where you will be living. Most municipalities require an appointment for registration. In Amsterdam, Rotterdam, The Hague, and Utrecht, appointments can book up weeks in advance, so schedule this before you even arrive if possible.
How to book:
- Online through your gemeente's website
- By phone (some have English-speaking staff)
- In person at the gemeente office (though they will likely tell you to book online)
Pro Tip: Amsterdam's gemeente is notoriously busy. Book your appointment the moment you know your arrival date. Waiting until you arrive could mean a two to three week delay, and that delay cascades into everything else.
Step 2: Gather Your Documents
Bring all of these to your appointment:
- Valid passport
- Birth certificate (apostilled and translated into Dutch or English by a certified translator)
- Proof of address (rental contract or letter from your landlord)
- Marriage certificate if applicable (apostilled and translated)
- Legalized documents for children if applicable
All US documents need an apostille. Get these from the secretary of state in the US state that issued the document. Do this well before your move because it takes time.
Step 3: Attend Your Registration Appointment
At the gemeente, a civil servant will:
- Verify your identity and documents
- Enter your information into the BRP (Basisregistratie Personen, the Dutch population register)
- Assign your BSN number
- Give you a confirmation letter
The appointment usually takes 15-30 minutes. Some municipalities give you your BSN on the spot. Others mail it to your registered address within a few days.
Step 4: Receive Your BSN Letter
You will receive a letter confirming your BSN number at your registered address. Keep this letter safe. You will need the number constantly in the coming weeks as you set up health insurance, open a bank account, and register your business.
What We Wish We Knew: Memorize your BSN or keep it in your phone. You will be asked for it more often than you expect. Every form, every phone call with a government agency, every medical appointment starts with "What is your BSN?"
What If You Cannot Register Immediately?
Sometimes you arrive before your rental contract starts, or you are staying temporarily with someone. Here are your options:
RNI registration: If you will be in the Netherlands for less than four months or do not have a permanent address yet, you can register at a RNI (Registration of Non-Residents) counter. This gives you a BSN but does not register you as a resident. Locations include Amsterdam Schiphol, Rotterdam, and several other cities.
Temporary address: Some municipalities allow you to register at a temporary address. Check with your specific gemeente.
Wait for your lease: If your rental starts soon, it is usually worth waiting a few days and registering at your actual address. Changing your registered address later requires another gemeente appointment.
After You Get Your BSN
Once you have your BSN, you can start knocking out the rest of your setup checklist:
- Get health insurance -- required within four months of registration. See our health insurance guide.
- Open a Dutch bank account -- most banks require a BSN. Check our guide on opening a bank account.
- Set up DigiD -- your digital identity for government services. Read our DigiD guide.
- Register with a huisarts -- your GP needs your BSN and insurance info. See our huisarts guide.
- Register at the KVK -- to officially start your DAFT business.
The order matters. Each step often requires completion of the previous one. BSN first, then insurance and bank account, then everything else.
Keeping Your Registration Current
Your BSN is permanent, but your registration details need to stay current. If you move to a new address, you must update your registration at the gemeente within five days.
Failing to update your address can cause serious problems: mail from the Belastingdienst going to the wrong place, issues with your residence permit, and problems with your insurance.
You can update your address online once you have DigiD, which makes the process much easier.
Frequently Asked Questions
Q: Is a BSN the same as a sofinummer? A: The sofinummer was the old Dutch tax number. It was replaced by the BSN in 2007. If you see references to a sofinummer in older documents or guides, it is the same concept. Everyone now uses the BSN.
Q: Can I get a BSN before arriving in the Netherlands? A: No. You must be physically present in the Netherlands to register and receive a BSN. You cannot apply from the US. However, you can book your gemeente appointment before arriving.
Q: What if I lose my BSN letter? A: Your BSN does not change, so you just need to find the number. Check old documents, tax letters, or your health insurance card (it is often listed there). You can also visit the gemeente to request your BSN again with valid ID.
