What is fax for in 2026?

Not a relic, not a snobbery: a tool that solves one precise problem — establishing that a document arrived.

Fax is crossing 2026 for one precise reason: while the page passes, the machine at the far end certifies its reception. No overloaded inbox, no spam filter, no relay server keeping a copy. The file moves directly between two numbers, and the sender has their answer within one to two minutes. Medical practice, court registry, insurance fund: for them, that certainty is worth more than the tool's age.

Four strengths email doesn't have

  • Delivery attested by the machine

    The transmission report rests on the acknowledgements sent back by the machine called during the call. Email says only this: your server handed it to the next one. As for read receipts, the recipient can simply decline to send them.

  • A failure that is never silent

    Busy tone, silence, or a cut-off mid-page: a fax reveals the problem immediately. An email, by contrast, can linger unnoticed in a spam or junk folder.

  • A corridor between two machines

    During the call, only two pieces of equipment talk to each other. No host stores the document in an inbox, no attachment sleeps for years on a third-party server.

  • A sender who identifies themselves

    The identifier of the sending machine and the caller's number are transmitted with each send. Faking an email address takes a minute; impersonating an allocated line takes a good deal more.

Who still asks for it

One thread links these trades: a lost page is paid for in delays, in reimbursements, in lost files.

Care and pharmacies
Prescriptions, liaison letters, laboratory results: between practice, pharmacy and hospital department, fax serves as the common language of software that doesn't understand each other.
The courts and lawyers
Pleadings and exhibits circulate between lawyers, bailiffs and courts; the transmission time-stamp sometimes decides whether a deadline was met.
Government offices
Government departments, and local authorities too, still publish a fax number as the official channel for submitting an application or a complaint.
Insurance and finance
Claims, direct debit mandates, insurance certificates: the transmission report carries weight when the date of submission is in dispute.

What keeps it in place

The decision is up to the recipient. A hospital or an insurance fund that publishes only a fax number compels every contact to use fax, whether or not they have a machine. It is exactly this gap that web-based sending platforms were created to fill.

On top of that, the current setup is hard to shift: outdated machines, quality procedures that still reference fax, and pre-printed forms with a number printed at the top. Switching channels means redoing every related process, training staff, and alerting partners — a change that keeps getting postponed as long as fax remains in use.

Who will take over

On its own merits, email never replaced fax, since it offers no reliable proof of delivery. Other channels have carved out niches: government submission portals, secure health messaging, electronic registered mail, and qualified signatures. They excel at traceability, but ask for registration, identity checks, and sometimes a paid subscription in return.

The shift therefore progresses one industry at a time, one nation at a time, one organisation at a time. Meanwhile, a simple question comes up for many people: how do you send a fax with no line and no machine?

The recurring questions

Is sending faxes still allowed?
Yes, without restriction: no text forbids it and plenty of organisations still ask for it. What varies is the weight of the transmission report, which changes with the country and the situation: most often a beginning of proof, never the equivalent of perfect proof.
Fax or email: which protects you best?
Each guards against a different risk. Analogue fax travels in clear, but leaves no copy in a hosted mailbox. Email is encrypted, but crosses several servers and accumulates in storage — so many doors for a hacked account.
Why such differences between countries?
Sector regulations and existing equipment account for most of the differences. Where authorities embraced digital early and a portal verifies the deposit, fax usage dropped sharply; in other areas, the established channel persists.
A fax machine at home, in 2026?
For an occasional fax, no: Faxeroo replaces the device — no hardware, no subscription. A machine still makes sense if you receive frequently, provided your line accepts it.
