Opening a Bank Account in Belgium as an Expat

Sorting out a bank account is one of the first things you will need to do after landing in Belgium: your landlord, your employer, your health insurer and the tax office all expect a Belgian IBAN. The good news is that the process is fairly standardised, and you often do not have to wait until every piece of your paperwork is in place to get started. Here is exactly what you need, what you can do before your national number arrives, and how to get your Bancontact card in hand.

What you need to open an account

Two things sit at the core of every application:

1. Proof of identity — a valid passport or national ID card. EU nationals can generally use their national ID card; non-EU nationals will usually add their Belgian residence card once issued.
2. Proof of a Belgian address — a rental contract, a recent utility bill, or an official document from your commune. Most banks want something dated within the last three months.

You must be 18 or older. Some banks also ask for an employment contract or recent payslips, particularly if you want a credit card or an overdraft rather than a plain current account. This is normal, not a red flag.

Bring printed copies to any branch appointment. Even banks that let you do most of the onboarding online sometimes want a physical signature or an in-person identity check for a first account.

Do you need your national register number first?

This is the question that trips up most new arrivals, so let us be precise.

Your national register number (the numéro national / rijksregisternummer, sometimes called the NRN) is issued when you register at your commune. But commune registration can take weeks, and you may need a bank account before then — for a deposit, a salary, or a rental guarantee.

In practice:

• You can often open an account before the number comes through. Several major banks will open a provisional account against your passport and lease, then ask you to supply the national register number within a set window (commonly around 90 days) once your commune registration completes.
• EU arrivals usually have the smoothest path — a passport or ID card plus a Belgian address is frequently enough to get started.
• A full-featured, permanent account normally does require the national number to be on file eventually. Treat the early account as a working account, not a loophole.

If in doubt, phone the bank and ask directly: "Can I open an account now with my passport and lease, and add my national number later?" Get the deadline in writing.

The big banks vs digital options

Belgium has three large retail banks with dedicated expat desks, plus a growing set of app-based options.

A practical note on app banks: many issue an IBAN from another EU country rather than a Belgian BE IBAN. EU rules ban "IBAN discrimination" — a business cannot legally refuse your salary or a direct debit purely because your IBAN is foreign — but in day-to-day Belgian life a BE-prefixed IBAN causes fewer snags with landlords, utilities and some employers' payroll systems. Many expats keep an app account for convenience and a Belgian bank account as their main one.

For the big banks, if you can verify yourself with itsme (Belgium's national identity app) or an eID card and reader, a large part of the onboarding can be done online.

Your legal right: the basic banking service

If banks turn you down — which can happen to new arrivals with thin paperwork — you are not stuck. Belgium has a basic banking service (service bancaire de base / basisbankdienst) that is a legal right for people residing legally in the country.

Key points, per the sector federation Febelfin and the federal economy service (FOD Economie):

• All private individuals resident in Belgium are entitled to it, including where ordinary applications have been refused. It also covers asylum seekers and recognised refugees, even with only a temporary address.
• It provides a current account with a debit card, the ability to deposit and withdraw cash, make transfers, set up standing orders and direct debits, and use digital banking — but not a credit card.
• A bank can only refuse in narrow cases: for example, if you already hold a comparable account, hold accounts or credit contracts above certain thresholds, or have committed fraud, money laundering or similar offences.
• It is not necessarily free. The maximum price is capped and adjusted each year in line with the consumer price index — check the current ceiling on the official source before assuming a figure.

To use it, contact a bank and explicitly ask for the basic banking service for individuals.

Timelines and getting your IBAN and Bancontact card

Roughly what to expect once your application is accepted:

• IBAN: often issued within a few working days if you are registered in a commune.
• Bancontact debit card: arrives by post, typically within one to two weeks, with the PIN sent separately for security.
• Non-EU applicants under enhanced checks: allow longer — potentially several weeks.

Your IBAN starts with BE and is what you give to your employer, landlord and the tax office. Your Bancontact card is the everyday debit card accepted almost everywhere in Belgium; many places prefer it to Visa or Mastercard for domestic payments.

Common problems and fixes

• "I have no proof of address yet." Ask whether the bank will accept your rental contract or a commune document while your registration is processing. Some accept a lease alone to start.
• "The bank wants my national number and I don't have it." Ask for a provisional account with a deadline (often ~90 days) to add it. Get the deadline confirmed in writing.
• "Everyone refused me." Invoke the basic banking service — it is a legal entitlement, not a favour.
• "My app-bank IBAN was rejected." Point to the EU ban on IBAN discrimination; but for a frictionless life, open a Belgian BE account too.
• "The appointment is in French/Dutch only." Ask for the bank's English-language expat service when booking — KBC Brussels and ING in particular market this.

Your next step

Before you book anything, gather one clean PDF each of your passport/ID, your signed lease, and any address document from your commune. Then contact one big bank's expat desk and ask the single most important question: "Can I open now with my passport and lease, and add my national number within 90 days?" That one call tells you whether you can bank this week or must wait for your commune registration.
