Fax, Customs & Freight 2026: Canada, Europe

Between a Montreal customs broker, an Antwerp freight forwarder and a Hamburg customs office, the fax has not vanished from cross-border supply chains. Here's who still reads a fax in 2026, what replaced it (CARM, AES, ICS2, PEC) and how to send an urgent document without a machine.

Short answer: international trade is one of the last industries where the fax number is still printed on letterheads, and it isn't nostalgia: goods stuck at a terminal cost money by the hour, and the freight forwarder picks the channel that gets through, not the one that is modern. In Canada, the Canada Border Services Agency has moved its commercial declarations onto the CARM portal and its single window, but customs brokers, bonded warehouses, trucking companies and regional offices still publish fax numbers for supporting documents, manifest corrections and release authorizations; the Canadian Food Inspection Agency and several permit programs do the same. In Europe, declarations must go through electronic systems (AES for exports, ICS2 for maritime and air security, ATLAS in Germany, AIDA in Italy, DUA in Spain, STADA in Portugal, PLDA/IDEV in Belgium), but the fax survives at the edges: a German Zollamt (customs office) asking for a signed certificate of origin, an Italian spedizioniere (freight forwarder) whose client has no PEC, a Portuguese agent who wants a legible bill of lading right now. From Europe to Canada, you dial 00 1 then the ten digits (514, 438, 450 in Montreal, 604 in Vancouver, 416, 905 in Ontario); to Germany 00 49, Spain 00 34, Italy 00 39, Portugal 00 351, Belgium 00 32.

About MondialFax. This article is an informational guide, with no connection to any Canadian, provincial or European customs administration, nor to any freight forwarder or carrier. 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 the supply chain keeps a backup fax

An import-export operation moves three very different families of documents, and they don't share the same channel.

  1. The declaration itself — the detailed declaration, the manifest, the security declaration. It has been 100% electronic for years, in every country MondialFax serves. No customs office accepts a declaration by fax in 2026.
  2. Supporting documents — commercial invoice, packing list, certificate of origin, EUR.1, phytosanitary certificate, bill of lading, air waybill, certificate of conformity. This is where the channels multiply: portal, email, fax, sometimes physical filing at a counter.
  3. Exception handling — an urgent correction, a release blocked on a Friday evening, a container sitting idle, a request from an inspector who wants "the signed page, not a patched-together scan".

The fax only holds its ground in categories 2 and 3, and always for the same reason: it requires no account, no digital identity, no certified mailbox at the sender's end. A Portuguese exporter who has to prove to a Canadian broker that their certificate of origin exists has no Italian PEC, no beA, no CARM credentials. They have a signed document and a number to dial.

That is also why warehouses and shipping agents' offices invest in a document scanner with an automatic feeder rather than a new fax machine: once the document is cleanly digitized, you choose the channel at the last minute.

Canada: CARM changed the declaration, not the brokers

Since the full rollout of CARM (CBSA Assessment and Revenue Management), every commercial importer in Canada must have a client portal account, financial security and a business number from the Canada Revenue Agency. Duty and tax accounting, statements of account and classification corrections all happen online. On that front, the fax really has disappeared.

But day-to-day practice remains hybrid:

  • Customs brokers in Montreal, Toronto, Vancouver and Halifax almost all publish a fax number on their shipping instructions, alongside an email address and a client portal. Many keep the fax because their manufacturing clients never migrated.
  • Cross-border trucking companies and freight brokers still use fax for bills of lading, proofs of delivery and customs instructions sent to a driver already on the road.
  • Bonded warehouses and terminals often require written delivery authorization; fax is accepted there because it lands on a printer in the shipping office, not in an inbox someone has to remember to open.
  • The Canadian Food Inspection Agency and several import permit programs (animal products, plants, regulated foodstuffs) have historically accepted documents by fax; numbers vary by regional office, so check the page of the office concerned before sending.

In Quebec, vocabulary matters: you'll be asked for a télécopieur (fax machine) and a courriel (email), and people will talk about a connaissement (bill of lading). A broker in Longueuil or Dorval will hand you a 450 or 514 number without blinking.

The habit to adopt: before faxing anything to a Canadian party, send an email asking "please confirm the expected channel and the active fax number". Numbers published on PDFs dated 2019 are everywhere, and a fax sent into the void triggers no alert at the recipient's end.

Europe: the declaration is closed, the margins are open

On the EU side, the framework is the Union Customs Code: mandatory electronic exchange, with a rolling calendar of successive systems. ICS2 has generalized pre-loading security declarations for maritime, road and rail; AES (Automated Export System) is replacing the old national export systems. None of these channels has a fax door.

The fax reappears as soon as you step outside the system:

CanadaCARMBrokers, warehouses, carriers, regional officesCARM portal, single window, secure email

Two patterns emerge. Countries that imposed a strong digital identity (Italy with SPID and PEC, Spain with Cl@ve, Portugal with the Chave Móvel Digital) have switched the fax off on the government side but not among private intermediaries. Countries that let private players organize themselves (Germany, Belgium, Canada) keep a more visible fax presence, simply because nobody had any incentive to unplug it.

The end of copper, logistics' hidden variable

The blind spot in 2026 is infrastructure. Europe's incumbent operators are shutting down their copper networks and PSTN switches in waves: Germany has largely moved to IP, Belgium, Spain and Portugal are working through regional timetables, Italy is pushing ahead with fibre. In Canada, the major carriers are gradually retiring analogue business lines in favour of SIP.

The very concrete consequence for an exporter: a fax number printed on a letterhead may be technically dead without anyone having removed it from the paper. The fax goes out, your sending service reports a failure, and the warehouse swears "the fax works fine". In practice, it works behind a badly configured analogue adapter, without T.38, and it fails half the time. We break this mechanism down in The end of copper outside France: your faxes country by country.

Logistics sites that tried to keep a physical backup line have usually given up: between the UPS for network equipment needed to ride out an outage and the upkeep of a machine nobody knows how to repair any more, the trade-off tips towards an online service. We put numbers on it in What a fax really costs in 2026.

Preparing a fax-ready customs file

A customs fax rarely fails for an exotic reason: it is almost always legibility or page order.

What must appear on the cover sheet. The forwarder's file number, the container or trailer number, the bill of lading or air waybill number, the declaration number if one exists, the vessel or flight name, the total page count, and a contact person with their full international dialling code. Without those references, your page lands in a pile and nobody knows which file it belongs to. The site offers a cover sheet generator so nothing gets left out.

What scans badly. Blue wet stamps, dry seals, fine barcodes, pale ballpoint signatures on recycled paper, and above all documents folded in three — the creases create black bands that swallow a row of figures. An A4 office guillotine to trim a bundle cleanly, or simply flattening the sheets the night before, saves a resend. For dense packing tables, scan in text / black-and-white mode at 200 × 200 dpi minimum, not in photo mode.

What must match across documents. Customs cross-checks: gross weight, net weight, number of packages, value, HS code, Incoterm. A 2 kg discrepancy between the invoice and the packing list is enough to trigger a request for an additional document — which will often reach you… by fax or email, depending on the office.

What you need to archive. Customs retention periods are long: three to ten years depending on the country and the procedure. Keep the timestamped transmission report with the file, not in a separate "fax" folder. An encrypted external hard drive or a backed-up off-site document vault avoids depending on a single machine, especially if the paper original is travelling. Our guide Archiving your faxes in 2026 covers formats and retention periods.

The time-zone trap on transatlantic flows

A Europe–Canada file often hinges on four hours of useful overlap. Montreal and Toronto are six hours behind Paris, Brussels, Berlin, Madrid and Rome; Lisbon is five hours apart; Vancouver nine. A fax sent from Milan at 4 p.m. arrives at 10 a.m. in Montreal: good window. Sent at 6 p.m., it arrives at noon, often right in the lunch lull. Sent on a Friday after 7 p.m. European time, it waits until Monday morning in a paper tray.

The other way round, a Canadian broker faxing at 3 p.m. Eastern reaches a European office at 9 p.m.: the release will wait. Port terminals run on shifts, but customs offices and forwarding agencies keep office hours, with summer closures in August in Italy, Spain and Portugal. We mapped those windows in Faxing across time zones: Quebec, Europe.

A handy rule of thumb: to reach an Eastern Canadian office during business hours (9 a.m. – 4 p.m. local), send from continental Europe between 3 p.m. and 10 p.m. For Western Canada, aim for 6 p.m. – midnight.

What a fax cannot do in a customs file

The limits need to be stated plainly, because the consequences are financial.

  • A fax is not a declaration. No customs procedure, anywhere in the seven countries served, is triggered by fax. Legal deadlines run from the electronic filing.
  • A fax does not prove origin. A faxed EUR.1 or certificate of origin is a working copy. The paper original or registered exporter status (REX) is what counts.
  • A fax is not confidential end to end. A commercial invoice contains prices, margins and contact details: it comes out on a shared printer. See Fax confidentiality: what the GDPR requires.
  • A fax has no read receipt. The transmission report proves the machine at the other end answered, not that a human read it. For an immobilized container, always back it up with a call.
  • Unsolicited commercial faxes are regulated. In Canada, CRTC rules on unsolicited telecommunications govern fax prospecting; in the EU, the ePrivacy Directive requires prior consent. Mass-faxing importers is a bad idea legally as much as commercially: see Fax mailing in 2026.

Frequently asked questions

Does the CBSA still accept documents by fax?

Not for commercial declarations, which go through CARM and the single window. Some regional offices and programs keep a number for specific documents; the only reliable source is the page of the office concerned, not a third-party directory. Ask for confirmation before sending.

Can a European freight forwarder insist on a fax rather than an email?

They may prefer it, especially for a signed document that has to reach a terminal immediately. But in Italy, PEC is the norm between businesses; in Spain and Portugal, the tax and customs portals are unavoidable for anything official. The fax remains a fallback channel, not a contractual one.

How do I send a fax to a Canadian broker without a fax machine?

From a browser. You dial 00 1 followed by the ten digits of the Canadian number, attach your PDF and get a transmission report back. The sending form is on the home page; open destinations are listed on supported countries.

Should a logistics site keep a dedicated analogue line?

Less and less. With copper being switched off, an analogue line is expensive, depends on an adapter and fails without any simple diagnosis. Sites that need to receive faxes are moving to a fax-to-email managed number; those that only need to send no longer need hardware at all.

Can a fax free up a container faster than an email?

Sometimes, and always for the same reason: it comes out on paper in the office that makes the decision. But the gain is a few minutes compared with a well-placed phone call. The right sequence is: call to announce, fax or email for the document, call to confirm receipt.

Key takeaways

  • Customs declarations are electronic everywhere: CARM in Canada, AES and ICS2 in the EU, ATLAS, AIDA, DUA, STADA and PLDA at national level. The fax has no place there.
  • Private intermediaries, however, still fax: Canadian customs brokers, German and Belgian forwarders, Spanish and Portuguese customs agents, Italian spedizionieri (freight forwarders).
  • Check every number before using it: the end of copper has silenced numbers that are still printed on letterheads.
  • Get the cover sheet right: file number, container, bill of lading, page count, contact with international dialling code.
  • Count the hours: 3 p.m. – 10 p.m. from Europe for Eastern Canada, 6 p.m. – midnight for the West.
  • Don't confuse a working copy with an original: certificates of origin, EUR.1 forms and transport documents each keep their own legal regime.
  • Always back it up with a call when goods are immobilized: a transmission report is not a read receipt.
