Neobank account frozen: why, and how to unblock it

A neobank account frozen overnight, with no reason and no notice: it is almost never a commercial sanction. It is a legal anti-money-laundering duty. The distinction sounds academic and it is not — it explains the institution's silence, and it points to the only method that actually gets an account unblocked.

A frozen account is a legal duty, not a punishment

When Revolut, N26 or bunq freezes an account, the institution is not expressing displeasure: it is applying the Belgian Law of 18 September 2017 on preventing money laundering, which requires ongoing due diligence for the entire duration of the business relationship.

In practice, an institution must know its customer's profile and check that transactions match it. As soon as a transaction falls outside that profile — an incoming transfer far above your usual amounts, a run of transfers to a higher-risk country, an expired ID document in the app, obviously professional activity on a personal account — it has to look into it before letting the money through, not afterwards.

The account is not being punished. It is on hold, pending a check the institution is not allowed to skip.

That duty weighs exactly the same on a large Belgian bank and on a neobank licensed in Lithuania or Germany: it is European law, transposed everywhere. What differs, and we get to it below, is when the check happens and how it is explained to you.

Why won't your neobank tell you why?

Because the law forbids it. If the institution has filed a suspicious activity report with the Cellule de traitement des informations financières — CTIF-CFI, the Belgian financial intelligence unit that centralises those reports — it cannot inform the person concerned. That is the prohibition of disclosure, and it exists for an obvious reason: warning the person under review would wreck the analysis before it began.

Hence those support exchanges that go in circles, those "we are carrying out a routine verification" messages on repeat, and the very unpleasant feeling of talking to a wall while the rent goes out in six days.

Worth knowing, so you do not spend your energy in the wrong place: the reason is the one thing nobody will ever give you, whatever tone you use and however many messages you send.

What works is the opposite. Supply, without being asked twice, whatever removes the doubt.

How long can a neobank account stay frozen?

It depends entirely on who is doing the freezing. And the most useful answer is also the most unpleasant one: a freeze decided by the institution itself is bound by no legal deadline at all.

The deadlines that do exist, as set out in the texts in August 2026:

Read the last row twice: it is what explains why accounts stay frozen anywhere from forty-eight hours to several weeks without anyone breaking the law. Nobody will give you a date.

But the second row is your lever. As long as you argue in the chat, no clock is running. The moment you file a formal written complaint, the fifteen-business-day deadline becomes enforceable, and it opens the door to the appeal routes. That is the single most useful switch in this article.

The objection: neobanks freeze faster, and explain less

True, and it would be dishonest to drown it in European law. The duty is identical; the lived experience is not.

Three reasons, none of which is an accusation. First, onboarding happens remotely in a few minutes, with a selfie and a photo of an ID card: part of the checking a Belgian bank used to do at the counter, in front of you, is deferred until after opening — so it happens later, on a live account. Second, volume and automation: detection is algorithmic, it casts a wide net, and human review follows at its own pace. Third, there is no branch where you can put a file on a counter.

Regulators pushed in that direction too. BaFin, N26's German supervisor, capped the bank's onboarding at 50,000 new customers per month in autumn 2021, raised that cap to 60,000 in early 2024, then lifted all growth restrictions on 1 June 2024 after more than €100 million invested in compliance — the special monitor appointed in late 2021 stayed in place. A supervisor demanding more controls mechanically gets more freezes.

The nuance that matters to you: it is not that a neobank is less reliable, it is that the check lands later and exits through a narrower channel. Complaining does not change that. Preparing your file before you need it does.

What should you actually do to get the account unblocked?

Answer with documents, fast, and once. A complete pack sent on day two beats six messages spread over three weeks: incomplete requests go back to the end of the queue.

What to gather before you write:

• A valid ID document, both sides, photographed flat and legible down to the small print.
• Proof of address less than three months old, in the same name and at the same address as the profile.
• Proof of the source of funds for the transaction that triggered the freeze: payslip, invoice, notarial deed, court decision, statement from the sending account.
• The contract, purchase order or email thread that explains an unusual incoming transfer.
• If you are self-employed: your company number at the Crossroads Bank for Enterprises and your latest VAT return.
• A dated timeline of your exchanges with support, screenshots included.

Send all of it through the official complaints channel, not the chat. At Revolut that means a dedicated complaints form and an email address separate from support; the others have their equivalent. State a precise request — lifting the freeze and restoring access to the funds — date it, and keep a copy of everything.

I had the case last spring on a Revolut account: an incoming transfer from a foreign client, far above my usual amounts, and the account went into restricted mode that same evening. Card still working, outgoing transfers refused. I sent the invoice, the contract and the sending account's statement straight away, and it was unblocked in four days. A friend of mine did the opposite at N26: two weeks of chasing in the chat without ever filing a formal complaint, and nothing moved until he did.

Write. That is all that counts.

Full freeze or partial freeze: not the same thing

Many freezes do not cut everything off, and the difference has very concrete consequences in Belgium.

A partial freeze usually lets incoming payments land and blocks outgoing ones: your salary arrives, you can see it, you cannot touch it. Sometimes the card keeps working while transfers are refused, sometimes the reverse. A full freeze shuts down the whole app, including access to statements — which makes building your own file harder, and is a good reason to export your statements regularly.

Either way, the real damage is elsewhere: SEPA direct debits bounce. Rent, insurance, energy, phone plan. Each rejection triggers fees from the creditor and, on the second one, a formal notice. Warn your creditors in writing on day one and offer a manual transfer from another account: a creditor who has been told almost never charges for the rejection, a creditor taken by surprise always does.

The freeze looks abusive: what are your options in Belgium?

Three steps, in this order, none of which costs money.

The first is a written complaint to the institution, the one that starts the fifteen-business-day clock. Without it, the other two are inadmissible.

The second depends on your institution's exact status, and this is the point nobody explains properly. Ombudsfin, the Belgian ombudsman for financial disputes, is only competent for institutions affiliated to it. Since Revolut operates through a Belgian branch — Revolut Bank UAB, Brussels branch, under partial supervision of the National Bank of Belgium and the FSMA, the Belgian financial markets authority — customers attached to that branch are pointed to Ombudsfin by the bank's own complaints policy; customers still attached to Revolut Bank UAB fall under the Bank of Lithuania. For N26, the route runs through the German supervisor; for bunq, through the Dutch financial ombudsman. When the competent body sits abroad, Ombudsfin can pass the file on through FIN-NET, the European network of financial ombudsmen: it works, it stretches the timeline, and the procedure sometimes runs in another language.

The third, in parallel rather than instead: the Belgian FPS Economy, whose Economic Inspectorate can be contacted about a payment service. Reporting is free and done online.

One honest limit to close on. None of these routes is fast, and none guarantees the freeze will be lifted: an ombudsman issues an opinion, not an order. What they really do is force the institution to justify its position in writing — and that is often the moment a file finally moves.

What this changes about how you organise your accounts

One rule, and it applies to everyone: never run your entire financial life through a single institution, neobank or not.

Belgian law provides a basic banking service so that nobody is left without an account, with a dedicated Chamber to settle refusals. That safety net is Belgian, and it does not reopen a frozen account in Vilnius or Berlin. A second account opened while everything is fine costs a few minutes; opened in a hurry, it takes several days of identity verification, exactly when you do not have those days.

In practical terms, for everyday use: keep a Belgian account alongside, export your statements once a quarter, and check that your ID documents have not expired in the app — an expired document is one of the silliest and most frequent triggers of all. If the account is lost to you anyway, our guide to closing a neobank account properly sets out the steps once the funds are back.

In short

A frozen neobank account is almost never a commercial decision: it is the anti-money-laundering due diligence imposed by the Belgian Law of 18 September 2017, and the prohibition of disclosure explains the silence you are met with. No legal deadline applies to a freeze decided by the institution; only a CTIF-CFI objection is capped, at five business days extendable by the public prosecutor. The lever does exist, though: a formal written complaint, backed by proof of the source of funds, starts an enforceable fifteen-business-day answer deadline and unlocks access to Ombudsfin or to the regulator of the licensing country.
