itsme & Digital Identity in Belgium (the App That Runs Everything)

If one app quietly runs adult life in Belgium, it is itsme. It is the federally recognised digital identity app — Belgium's answer to Sweden's BankID or Denmark's MitID — and once it is set up you use it to log in to your bank, file your taxes, check your pension, deal with your health insurer and legally sign contracts, all with a single five-digit code. This guide explains what it is, how to activate it (you need a Belgian bank card or an eID), and how it fits together with Bancontact for everyday payments.

What itsme actually is

itsme was built by four of Belgium's biggest banks — Belfius, BNP Paribas Fortis, ING and KBC — together with the country's main telecom operators. That origin matters: it means the same identity you already trust for banking has been extended to government and private services. Around 7 million people use it, and roughly one million logins a month go through it to government websites alone.

Practically, itsme replaces the old world of card readers, passwords and paper tokens with one app and one five-digit personal code (or your fingerprint / Face ID). You install it once, prove your identity once, and from then on it is your key to hundreds of services.

What you can do with it

• Bank — log in to your online and mobile banking, and confirm larger transfers or new payees.
• Government (via MyGov / the federal login) — file your taxes on Tax-on-web / MyMinfin, check your pension on mypension.be, read official post in eBox, and access social-security services.
• Health — log in to your mutuelle / mutualité / ziekenfonds, and to health portals such as masanté / mijngezondheid to see your medical record, prescriptions and vaccinations.
• Sign documents — itsme Sign produces a qualified electronic signature, which under EU law has the same legal value as a handwritten signature. You will use it for rental contracts, employment paperwork and more.
• Private companies — it works at well over a thousand companies and platforms (insurers, telecoms, utilities, notaries) to log in, open accounts and confirm transactions.

itsme is free for you as an individual. The businesses that accept it pay for the service.

How to activate itsme

There are two official ways in, and which one you can use depends on what you already have. Both are done once; after that you only ever need your phone.

In both cases you also need a smartphone with the itsme app installed and a mobile phone number to receive an activation code by SMS.

Route 1 — activate via your bank (usually the fastest for new arrivals)

If you have already opened a Belgian bank account, this is normally the quickest path.

1. Download itsme from the App Store or Google Play and open it.
2. Enter your mobile number and email, choosing the correct country code.
3. Choose "Activate via your bank" and pick your bank from the list (BNPPF, Belfius, KBC, ING, Hello bank!, Fintro).
4. Log in to that bank's secure environment as you normally would — with your bank card and card reader — to confirm your identity.
5. Set your five-digit itsme code and confirm the SMS verification code. Done.

Note that the via-bank route is only available for customers whose account is tied to a Belgian eID with a chip — so it still assumes you have (or will soon have) a Belgian ID.

Route 2 — activate via your eID

If you have your Belgian electronic identity card (eID):

1. Install itsme on your phone.
2. On a computer, go to the itsme activation page and enter your phone number and email.
3. Connect your card reader, insert your eID, and sign the itsme contract by entering your eID PIN. (If you have a newer NFC eID and an NFC phone, you can scan the card with the phone instead of using a reader.)
4. Open the app, enter the identification token shown, then the SMS code, and set your five-digit code.

Once activated, you never need the card reader again for day-to-day logins.

The catch for new expats: the national register number

Here is the part that trips people up, so be clear-eyed about it. Full government access through itsme relies on your national register number — and that number lives on a Belgian eID. Until your commune registration comes through and you receive your Belgian eID, itsme can cover your banking and private-company needs, but government logins may be limited or unavailable.

You are not stuck in the meantime. The federal digital-services agency BOSA offers alternatives:

• A security code sent by email — BOSA describes this as one of the simplest keys, and it works without an eID.
• Digital keys applied for in person at a registration office (often your commune), which issues an activation code on paper. This route is explicitly aimed at people who cannot use eID or itsme yet, including some foreign and cross-border workers.
• ForReg, a system for accessing certain federal tax e-services for people without traditional Belgian authentication — useful for non-residents and brand-new arrivals.

So the honest sequence is: register at your commune → get your national number and Belgian eID → then activate itsme for the full experience. See our guides on the national register number and opening a bank account for how those pieces slot together.

itsme vs Bancontact vs Bancontact Pay — what pays for what?

These get muddled constantly, so keep the roles straight: itsme proves who you are; Bancontact moves your money.

• Bancontact is Belgium's domestic debit card scheme — the card you get with your account, accepted almost everywhere, and often preferred over Visa/Mastercard for local payments.
• Bancontact Pay is the phone app for paying by QR code in shops, online, in apps, and to friends. It is the same app many people still know as Payconiq by Bancontact — the company is rebranding it to Bancontact Pay in spring 2026 via an automatic update, and existing features are unchanged. It has around 2 million users and is accepted at 290,000+ merchant locations.
• Wero, the pan-European payment system, is also rolling out across 2026; the same in-store QR codes are being made to work with it.

Where itsme comes in: when you set up the payment app, add a new payee in your banking app, or confirm a bigger transfer, you will often be asked to confirm with itsme. Think of itsme as the bouncer and Bancontact as the wallet.

Common problems and fixes

• "I have no eID yet, so government sites won't let me in." Correct — that is by design. Use the BOSA email security code, or apply for digital keys in person at your commune, until your Belgian eID arrives. Then activate itsme.
• "My bank isn't in the itsme list." Use the eID route instead (computer + eID + card reader/NFC). It works regardless of who you bank with, once you have a Belgian eID.
• "I changed my phone or number." itsme is tied to your device and number. Changing either means re-activating — keep your card reader or bank card handy so you can re-verify.
• "I don't have a card reader." They are cheap and sold in supermarkets and electronics shops (any generic EMV/eID reader works). If your eID and phone both support NFC, you may be able to skip the reader entirely.
• "itsme won't send the SMS code." Check the country code on your number and that you have signal; the code arrives from a short code, not a normal number. Sort out a Belgian SIM early to avoid this class of problem.
• "I want a backup for logging into government sites." Install the MyGov.be app and set up the email security code via BOSA — useful if you ever lose access to your itsme phone.

Your next step

Before anything else, get a Belgian SIM and open (or confirm) your Belgian bank account — those two things unlock the fastest itsme activation. Then download itsme and run the "Activate via your bank" flow today; it takes about ten minutes and turns dozens of future logins into a single five-digit tap.

Rules, brand names and numbers change — itsme's Payconiq/Bancontact Pay rebrand and the Wero rollout are both in progress during 2026. Verify anything time-sensitive against the official sources linked above before you rely on it.
