Short answer: Belgium never banned the fax the way Italy did with its Codice dell'amministrazione digitale, and yet fax use has declined there more quietly and almost as fast. Brick by brick, the country built a mandatory digital layer: eBox (the official electronic mailbox for citizens and businesses), MyMinfin for tax matters, e-Deposit and DPA-deposit for court filings, Itsme and the electronic identity card for authentication. The result: in 2026, most fax numbers at federal public services have been pulled from contact pages, but local pockets remain alive and well — municipal administrations in small districts, public social welfare centres (CPAS), justice-of-the-peace registries, health insurance funds, medical and dental practices, notaries, building managers, hotels and garages. From France, Quebec or Germany, three habits are enough: check the number on the official website the same day, dial 00 32 followed by the number without its leading zero, and back up the transmission with an email or eBox message whenever a deadline is at stake.
About MondialFax. This article is an informational guide, with no connection to any Belgian administration or operator. MondialFax sends faxes free of charge and without registration to seven destinations (France, Belgium, Germany, Spain, Italy, Portugal, Canada) from a browser, with a daily sending limit. It does not assign a number and does not handle reception. See the Belgium page and the supported countries.
Why the Belgian fax faded away without a sound
Italy killed the fax by decree, Germany through pressure from bar associations and health insurance funds. Belgium went about it differently: it made the digital channel so convenient and so widespread that fax numbers simply stopped being updated, then vanished from directories without any legal text ever abolishing them.
Three factors compound each other.
Institutional density. A Belgian case file readily crosses four levels: federal, regional (Flanders, Wallonia, Brussels-Capital), community and municipal. Each level digitised at its own pace, with its own portals — Wallonia's Mon Espace, Flanders' Mijn Burgerprofiel, Brussels' IRISbox. A counter that has migrated to its regional portal has no reason to keep a fax machine; a counter that has not migrated sometimes keeps the one it has had for fifteen years.
eBox, the decisive factor. Rolled out by BOSA (the Federal Public Service Policy and Support), the citizen eBox receives official mail from dozens of institutions — ONEM, INAMI, the FPS Finance, family allowance funds. On the business side, eBox Enterprise is tied to the company's CBE number. An administration that pushes its notifications into the eBox is no longer keen to accept an inbound fax stream: the internal scanning workflow no longer exists.
Bilingual form overhauls. Many services used the redesign of their online forms (FR/NL/DE) as an opportunity to remove "paper-equivalent" filing routes, including the fax. The web form has become the only official door.
And what about copper?
Proximus has begun the gradual shutdown of its copper network in favour of fibre, on a timetable stretching to the end of the decade, area by area. Unlike France, Belgium has not announced a single national switch-off date for analogue residential and business lines: the cut happens neighbourhood by neighbourhood, at the pace of the fibre rollout. The very concrete consequence for a sender abroad: a Belgian fax number that worked in March may no longer answer in November — not because the recipient changed their mind, but because their line was switched over and the machine was never reconnected. We cover this mechanism in detail in our feature on the end of copper outside France.
Who still accepts a fax in Belgium in 2026
The table below reflects practices observed on official contact pages and in common professional use. It is never a substitute for checking on the day.
| Recipient | Fax in 2026 | Expected official channel |
|---|---|---|
| FPS Finance (income tax, VAT) | Virtually none | MyMinfin, Intervat, eBox |
| ONEM, INAMI, health insurance funds | Rare at head office, persistent in local branches | Portals, eBox, email |
| Court registries (civil, enterprise) | Backup only | e-Deposit, DPA-deposit (lawyers) |
| Justices of the peace, small courts | Still alive | Email + paper filing |
| Municipal administrations (< 15,000 inhabitants) | Often active | Online counter, IRISbox, email |
| CPAS (public welfare centres) | Variable, often active | Email, in-person filing |
| Medical and dental practices | Active | eHealthBox, secure email |
| Hospitals (internal departments) | Active internally | eHealthBox, health networks |
| Notaries | Residual | e-Notariat, eBox, Itsme |
| Building managers, estate agencies | Active | |
| Hotels, garages, campsites, small trade businesses | Active |
The most important line in this table is the last one. The Belgian fax survives above all in the local business fabric: a group booking at a hotel in the Ardennes, a purchase order with a wholesaler, a repair authorisation at a body shop, a termination form sent to a building manager. These are flows where the fax carries no particular legal weight, but where it remains the way the house has always done things.
The court angle, worth knowing before you send
On the judicial side, Belgium has moved fast. e-Deposit allows electronic filing of pleadings and exhibits with the courts, and DPA-deposit, the tool of the legal profession (Digital Platform for Attorneys), has become the standard for communications between lawyers and registries. A fax sent to a registry in 2026 stands a good chance of being treated as mere information, not as an enforceable filing. The rule is the same as in Italy or Germany: fax to give notice, file through the designated channel. Our guidance on this point is gathered in the article devoted to the fax as evidence.
Dialling a Belgian number correctly from abroad
This is the leading cause of failure, well ahead of line outages.
Belgium uses country code +32. National numbers are written locally with a leading zero (02 for Brussels, 03 Antwerp, 04 Liège, 09 Ghent, 071 Charleroi, 081 Namur, 061 Libramont, and so on). From abroad, that zero disappears.
- Number as displayed:
02 123 45 67 - From France, since Belgium does not use closed numbering:
00 32 2 123 45 67 - From Quebec or elsewhere in Canada:
011 32 2 123 45 67
Two recurring traps:
- Numbers with three-digit area codes (
071,081,061,056, etc.) have a six-digit subscriber number. You drop the zero from the area code, not a digit from the number. - 0800 and 070 numbers are either unreachable from abroad or reachable at a very different rate. If a contact page only lists an
0800, you need to track down the service's geographic number.
The area code directory brings together these prefixes for the seven destinations served. And for sending from a third country, the guide sending a fax abroad details the most common prefix mistakes.
Time zones, a non-issue… except from Quebec
Brussels, Paris, Berlin, Madrid, Rome and Lisbon-minus-one share the same hour or nearly: a French sender has nothing to calculate. From Montreal, on the other hand, there is a six-hour gap. A fax sent at 9 a.m. Eastern time arrives at 3 p.m. in Namur — still within working hours. Sent at 2 p.m. in Montreal, it lands at 8 p.m.: it will wait until the next morning, and the day's filing deadline will be missed. For sensitive files, the useful window from French-speaking Canada falls between 2 a.m. and 10 a.m. local time — which is to say you prepare the transmission the night before.
Preparing a fax that gets through first time
Image quality remains the second cause of failure, particularly when the page has travelled as a photo taken on a phone.
Three moves change everything.
Scan at 300 dpi in greyscale, not in colour. A fax transmits black and white: a colour page is converted by thresholding, and pale fills disappear. For regular volumes, a portable sheet-fed document scanner produces more consistent pages than a hand-held smartphone, and avoids the keystone distortion that makes stamps illegible.
Avoid documents folded in four. Creases create black bands that cause recognition to fail at the receiving end. A laminating pouch, or simply a few hours under a paperweight, is enough to flatten them out.
Check the contrast of signatures. A signature in pale blue ballpoint evaporates. A pigmented black ink rollerball pen stays legible after two generations of faxing — a trivial detail, and a real cause of rejections. We devoted a whole article to scanning settings in illegible fax.
The cover sheet, mandatory in practice
In Belgium as elsewhere, a fax arriving without a cover sheet in a department where ten people share one machine ends up in an anonymous tray. The cover sheet must carry: a named recipient or a specific department, the language of the file (FR, NL or DE — a Flemish file handled in French gets delayed), the file reference, the number of pages, and a way to call back. The site's cover sheet generator produces this format in a few clicks.
One last hardware tip: if you are sending from an analogue line that is still in service, a UPS with telephone line surge protection prevents drops mid-transmission, which force you to start over and eat into your daily sending limit.
And if the fax no longer gets through? The Belgian channels to know
When the line stops answering, you need to know where to switch to. Here are the Belgian equivalents of the channels you may know elsewhere.
- eBox (BOSA) — the official mailbox for citizens and businesses, accessible via Itsme or an electronic identity card with a reader. It is Belgium's counterpart to Italy's PEC for inbound official mail.
- MyMinfin — everything tax-related: returns, certificates, exchanges with the FPS Finance.
- IRISbox (Brussels), Mon Espace (Wallonia), Mijn Burgerprofiel (Flanders) — regional and municipal procedures.
- e-Deposit / DPA-deposit — court filings.
- eHealthBox — the secure messaging system for the healthcare sector, built on the eHealth platform.
For procedures that require the electronic identity card, a USB eID card reader remains necessary on a computer when Itsme is not an option — typically for non-residents who do not have a Belgian phone number.
Advertising faxes to Belgium: the red line
One point not to overlook if you do outreach. Unsolicited faxes sent to a natural person are governed in Belgium by the Code of Economic Law and by the GDPR: sending advertising by fax requires prior consent (an opt-in regime), and using the fax for canvassing is one of the cases most clearly targeted by European rules on unsolicited communications. The Data Protection Authority (APD/GBA) handles such complaints. In other words: a bulk commercial fax campaign to Belgium is not a grey area, it is a risk. The details of the European and Canadian regimes are set out in our article on fax mailing and consent.
Frequently asked questions
Does a fax have legal force in Belgium?
There is no legal text granting a fax standalone evidential value. A fax amounts to a prima facie written indication, which the judge weighs at their own discretion, and the transmission report establishes only that it was sent — not that it was read. As soon as a limitation period, an appeal or a court filing is at stake, the official channel (e-Deposit, eBox, registered mail) is the only safe one. The page on the legal value of the fax compares the three routes.
Can I send a fax to Belgium without a fax machine?
Yes. An online service transmits a PDF to a Belgian number without any machine or analogue line. MondialFax does it free of charge and without registration from the sending form, with a daily sending limit. On the other hand, no free service assigns you a Belgian number: to receive, you need a subscription with an operator, as explained on the receiving a fax page.
Should I write in French, Dutch or German?
It depends on the region and the service. A Flemish administration works in Dutch, a Walloon administration in French, the municipalities of the German-speaking Community (Eupen, Sankt Vith) in German, Brussels in French and Dutch. A file sent in the wrong language is not rejected as a matter of principle, but it is invariably slower. State the language on the cover sheet.
Why is my Belgian fax number permanently busy?
Three causes, in order of frequency: the number has been cancelled but still appears on a web page that has not been updated; the line has switched from copper to fibre and the machine has not been reconfigured; or the fax machine shares its line with a telephone and a human is picking up. Call the number by voice: if a voice answers, the fax will never get through.
Does a fax sent on Friday evening arrive before Monday?
Technically yes, it prints out or lands in the fax-to-email inbox. In practice, it will be read on Monday. Belgian administrations largely work 8.30 a.m. to 4.30 p.m., with municipal counters that sometimes close on Friday afternoons. For a deadline falling on a Monday, aim for Thursday.
Key takeaways
- Belgium did not ban the fax: it made it pointless at federal level through eBox, MyMinfin, e-Deposit and Itsme.
- The pockets still active in 2026 are local and private: small municipalities, CPAS, justices of the peace, medical practices, notaries, building managers, hotels and small trade businesses.
- From abroad, dial
00 32(or011 32from Canada) then the number without its leading zero;0800and070numbers are unreliable. - The copper shutdown proceeds neighbourhood by neighbourhood, with no single national date: a number valid yesterday may be dead tomorrow.
- For anything with a deadline, back it up by email or through the official channel and keep the transmission report with the Belgian local time.
- Advertising faxes to Belgium require prior consent: no bulk canvassing.
