Faxing Abroad: Which Language Should You Use?

Short answer: a fax sent from France or Quebec to Germany, Italy, Spain, Portugal, Belgium or English-speaking Canada fails far more often for a linguistic reason than for a technical one. The rule that works: cover sheet in the recipient's language, short, factual, with a subject line that names the local procedure (Vorgangsnummer, numero di pratica, número de expediente, file number) ; body of the document in the original language, untouched, never re-translated by hand; and a bilingual callback line stating how to reach you. Three physical precautions come on top: avoid characters that fax transmission mangles (ß, ñ, ã, ç, cedillas and umlauts stay legible at 200 dpi but not in draft mode), write dates in an unambiguous format (12 March 2026 rather than 12/03/2026, unreadable for an English-speaking Canadian correspondent), and dial the number in international format: 00 + country code from France, 011 + country code from Quebec.

About MondialFax. This article is an informational guide, with no connection to any telecom operator, government body, sworn translator or official directory. 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 incoming faxes. See the supported countries page and the dialling code directory.

Why language decides the fate of a cross-border fax

A fax has no clickable subject line, no verifiable sender, no conversation thread. It lands on a printer or in a shared fax-to-email inbox, and someone decides within ten seconds whether to forward it to the right department or drop it on the "later" pile. That decision is made solely by reading the cover sheet.

When that sheet is in French and the person picking it up works in Hamburg, Milan or Mississauga, three things happen:

• they look for a department name they recognise, fail to find one, and route the document at random;
• they cannot spot the file reference, so they cannot attach the document to an existing case;
• they have no way of getting back to you, because your phone number is not in international format.

None of these three failures will show up in your transmission report: the report will say "sent, 2 pages, 38 seconds". That is the difference between a technically successful fax and a fax that actually arrived, a gap already detailed in our article on the fax confirmation receipt.

The two-layer rule: translated cover sheet, untouched document

The temptation, when sending a file abroad, is to translate everything. That is a bad idea for supporting documents: a bank statement, a civil status certificate, an invoice or a prescription derive their value from their original form. A document re-translated by hand is no longer the document, it is a commentary on it — and many administrations will reject it.

Hence the two-layer rule:

If a translation is required (recognition of a diploma, civil status record, document for a court), it must be done by a sworn translator and added to the file: it does not replace the original. To know in advance what will be expected of you, a bilingual legal dictionary on the shelf is more useful than a machine translator, because it gives you the exact word the administration uses, not an approximate synonym.

Country by country: the language that opens the door

Germany

German, with no useful exception. German firms, insurers and technical departments still receive a great many faxes, but their internal procedures are strictly German-language. Two words make all the difference on the cover sheet: Betreff: (subject) and Aktenzeichen or Vorgangsnummer (file reference). Use Seitenzahl: 3 (number of pages: 3) for the page count.

As for competing channels, a French sender should know that German lawyers communicate with each other via beA and healthcare professionals via KIM: these networks are closed to non-members, which explains why you are redirected to a fax number. The details are in our article on faxing to Germany.

Italy

Italian. The key vocabulary: Oggetto: (subject), numero di pratica (case number), protocollo (registration reference). That last word is central: the Italian administration "protocols" incoming items, and a document without a protocol reference simply drifts. Note too that PEC (posta elettronica certificata, certified electronic mail) has become the official channel for virtually every exchange with Italian public bodies, which reduces the fax to a fallback channel for companies and a handful of professional practices.

Spain

Castilian Spanish works everywhere, but be aware that some regional contacts (Catalonia, the Basque Country, Galicia) work in their co-official language: they will read Spanish without difficulty. The useful words: Asunto: (subject), número de expediente (file number), Registro (registry). The registro electrónico (electronic registry) has largely absorbed administrative filings, so your Spanish faxes will mostly go to companies, private clinics and property management firms.

Portugal

European Portuguese — not Brazilian Portuguese, some of whose administrative phrasing differs. Assunto: (subject), número de processo (case number), NIF (the tax identification number, required for almost everything). Portugal's postal service CTT and its financial institutions have moved online, but the fabric of small businesses and professional practices remains reachable by fax.

Belgium

This is the trickiest case, because the answer depends on the municipality, not the country. A number in Antwerp, Ghent or Bruges: Dutch. Liège, Namur, Charleroi, Mons: French. Eupen and the Eastern Cantons: German. Brussels: bilingual French-Dutch, and a French cover sheet will get through anywhere there. Sending French to Antwerp is not a breach of etiquette, it is a loss of efficiency: the document will wait until a bilingual colleague walks by. Our guide to faxing to Belgium details the competing Belgian channels, including eBox.

Canada

Two Canadas. In Quebec, French, with the local vocabulary: télécopieur (fax machine), télécopie (fax), courriel (email), numéro de dossier (file number). Elsewhere — Ontario, Alberta, British Columbia, the English-speaking Maritimes — English, with Re:, file number, page 1 of 3. Federal bodies (IRCC, CRA, Service Canada) work in both official languages, but a unilingual regional office will take days to get a French cover sheet translated. When in doubt, an English cover sheet with the file reference prominently displayed is the safest choice.

What fax transmission does to accents, figures and dates

A fax transmits a black-and-white image, with no greyscale in standard mode. Three very concrete consequences for a multilingual transmission.

Diacritical marks are lost at low resolution. A German ß mistaken for a B, a Spanish ñ whose tilde vanishes, a Portuguese ã turned into a, a swallowed cedilla: the proper name becomes impossible to find in the recipient's database. The defence is twofold — write proper names in spaced capitals on the cover sheet (MÜLLER stays legible even if the umlaut fades) and send in fine resolution, 200 × 200 dpi minimum. Our guide to illegible faxes gives the detailed settings.

Handwritten figures are a trap. A European 1, with its upstroke, is easily read as a 7 by an English-speaking Canadian reader, who writes 1 as a plain vertical stroke. And the French crossed 7 does not exist in North America. Type your figures, do not write them by hand. If you have to annotate a paper document before scanning it, a good opaque black ink pen produces a stroke that fax reproduces crisply, whereas a highlighter or a light ballpoint disappears entirely.

Dates must be made unambiguous. 03/12/2026 means 3 December in France, Belgium and Spain, and 12 March on an English-Canadian form filled out American-style. Write the month in words in the recipient's language, or use the 2026-12-03 format (ISO 8601 standard), understood and used in Canada. Same logic for amounts: 1 250,50 € becomes meaningless where the comma is a thousands separator. State the currency in letters (EUR, CAD) and separate thousands with a space.

A cover sheet template that works in all six destinations

The structure stays identical; only the labels change language. Eight lines, no more.

1. The word "fax" in the target language — Telefax, Fax, Telecopia, Telecópia.
2. Recipient: the department's name as it is called locally, then the person's name if you have it.
3. Sender: your name, your organisation, your country.
4. Subject: Betreff / Oggetto / Asunto / Assunto / Re: — one line, naming the procedure.
5. Reference: the local file number, in large characters.
6. Page count: Seite 1 von 3, pagina 1 di 3, página 1 de 3, page 1 of 3.
7. Two or three sentences of body text, in a polite imperative or infinitive form, stating what you are asking for.
8. Contact: phone in +33 … or +1 … format, email, and local hours when you can be reached.

Our cover sheet tool produces the framework; all that remains is to swap the labels. For polite phrasing, a bilingual business correspondence guide — business German, Italian or Spanish — prevents the two mistakes that undermine a transmission's credibility: unintentionally over-familiar address and a closing formula copied straight from French.

If you send faxes to several countries regularly, prepare one cover sheet per destination and archive them in a single folder. Three hours of work once, and never again an improvised translation at 5 p.m. on a Friday.

The question of time zones and reading delays

A perfectly translated cover sheet is useless if it arrives at 3 a.m. in an office that prints the night's faxes in one disorderly batch. Two reference points:

• from France to Germany, Italy, Spain, Portugal and Belgium, the time difference is zero or one hour (Portugal: one hour behind);
• from France to Quebec, it is six hours; to British Columbia, nine hours. A fax leaving Paris at 2 p.m. arrives at 8 a.m. in Montreal, right at opening time: that is the ideal slot. Sent at 6 p.m., it arrives at noon, during the lunch break.

Our article on time differences details the best slots. To avoid calculating every time you send, a dual time zone wall clock above the workstation settles the matter for good — it is the single most useful office accessory for a team faxing across two continents.

And for advertising faxes: language saves nothing

A point of law that is often misunderstood: translating a commercial fax into the recipient's language does not make it lawful. In the European Union, the "privacy and electronic communications" directive and its national transpositions require prior consent for fax marketing to individuals, and the rules for businesses are strict. In Canada, the National Do Not Call List managed by the CRTC explicitly covers faxes, and CASL governs commercial electronic messages. Unsolicited bulk sending remains an offence, whether it is written in impeccable German or shaky French. The topic is covered in our article on fax mailing and consent.

Frequently asked questions

Should the supporting documents attached to a fax be translated?

No, unless explicitly required. Documents are sent in their original language; a sworn translation is added if the administration asks for one. A do-it-yourself translation exposes you to rejection for non-compliance.

Does English work everywhere?

It works in large companies and international departments, poorly in small businesses and local administrations in Germany, Italy, Spain and Portugal. To Canada outside Quebec, it is on the contrary the only reasonable option. Simple rule: English by default only to English-speaking Canada, the local language everywhere else.

Is a machine translator good enough for a cover sheet?

For eight factual lines, yes, provided you only translate short sentences and check the procedure names with the recipient or on their website. The classic mistake is to translate a French administrative term literally when it has no local equivalent.

How should I write my callback number?

Always in international format with the +: +33 1 23 45 67 89, +1 514 123 4567. A number written 01 23 45 67 89 cannot be dialled from Berlin or Toronto. Add the local hours when you will answer.

What if I don't know which language my Belgian recipient speaks?

Go by the municipality, not the area code. If you are completely unsure, a cover sheet in French and Dutch, two columns, eight lines each, fits on one page and settles the question.

Key takeaways

• The cover sheet gets translated, the transmitted document never does: its value lies in the original.
• Germany → German, Italy → Italian, Spain → Castilian Spanish, Portugal → European Portuguese, Belgium → depends on the municipality, Canada → French in Quebec, English elsewhere.
• Name the file reference using the local word: Aktenzeichen, protocollo, expediente, processo, file number.
• Write proper names in capitals, send at 200 dpi, type figures rather than writing them by hand.
• Write dates in words or in 2026-12-03 format, state the currency, and give a callback number in +33 / +1 form.
• Respecting the language never exempts you from CRTC or European Union consent rules for commercial transmissions.
