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. A read receipt, for its part, depends on the recipient's goodwill.

  • A failure that is never silent

    Engaged, silent, cut off mid-page: fax tells you the failure at once. Email, on the other hand, can sleep in a junk folder without anyone noticing.

  • 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

It is the recipient who decides. A hospital or an insurance fund whose only address is a fax number puts every one of its correspondents under an obligation to fax, machine or not. Browser-based sending platforms owe their existence to that gap.

Add to that the existing setup: machines long since written off, quality procedures that mention fax, pre-printed forms with a number at the top. Changing channel means rewriting everything, training people, warning partners — a project put off for as long as fax keeps running.

Who will take over

On its own ground, email never took fax's place: it does not prove delivery. Others have nibbled at its uses: government deposit portals, secure health messaging, electronic registered mail, qualified signatures. Strong on traceability, they demand in exchange registration, identity verification, sometimes a subscription.

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 questions that keep coming up

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 rules and existing equipment explain almost everything. Where the administration turned digital early, with a portal that proves the deposit, fax plummeted; elsewhere, it remains the recognised channel.
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.
