Does a cover letter need a signature?

What the official English-language guidance says

SECO runs arbeit.swiss, the federal employment service behind the regional employment centres, and it publishes its application advice in English as well as the three national languages. Its list of what a cover letter should contain runs: your postal address, the company's postal address, date, subject heading, opening salutation, closing greeting and signature. That last item is the answer in its shortest form.

The same list appears unchanged in German, French and Italian. That matters more than it looks: on several application questions the language versions of Swiss official pages drift apart, because they are revised at different times. Here they do not. A signature is treated as a structural part of the letter in all four.

What no version explains is how a signature reaches a document that will never be printed. That gap is where the confusion lives, and where the official sources start to disagree with each other.

The legal position, which is shorter than people expect

The Swiss Code of Obligations regulates signatures only for contracts that the law requires to be in writing. Article 13 paragraph 1: a contract required by law to be done in writing must be signed by all persons on whom it imposes obligations. Article 14 paragraph 1: signatures must be appended by hand. Paragraph 2 allows a mechanically reproduced signature only where such reproduction is customarily permitted, giving securities issued in large numbers as the example.

None of that touches hiring. Article 320 paragraph 1 states that, except where the law provides otherwise, the individual employment contract is not subject to any specific formal requirement. An employment relationship can even arise simply because an employer accepts work that in the circumstances could only be expected in exchange for salary. If the contract itself needs no form, the letter asking for the job certainly does not.

Two useful consequences follow. Your pasted signature image is not a signature within the meaning of Article 14 paragraph 1, so nothing in the letter binds you. And there is no rule to break by leaving it out — what remains is a custom, and customs are noticed rather than enforced.

The one legally weighty option, the qualified electronic signature under Article 14 paragraph 2bis combined with a qualified time stamp, is deliberately heavy: it costs money, requires an identity check and answers a question nobody in a recruitment process is asking.

What is actually inside the official model letters

berufsberatung.ch and its French and Italian siblings are run by the Swiss Service Centre for Vocational Education, on behalf of the cantons. They publish three finished example letters as PDFs, named after their invented senders — Aurora, Elias and Victoria. We downloaded all three and inspected the file contents rather than the rendering.

None of the three contains a single image object: no photograph, no scan, nothing. All three embed one extra typeface alongside the text fonts — Bradley Hand ITC Bold, an imitation of handwriting. In the Victoria example the only text set in that typeface is the string «Victoria Muster», sitting between the closing greeting and the typed name. Aurora and Elias do the same with their own names.

The French version of the page gives the opposite instruction. On orientation.ch the item is «signature manuscrite», with an explicit note: you can digitise your signature, for example by scanning it, and insert it into the letter before saving as PDF, if you are applying entirely online. The three French example letters nevertheless contain no image either, and embed the same handwriting typeface.

The Italian page contradicts itself within a single screen. Its checklist reads «Cordiali saluti, firma elettronica, nome e cognome» — an electronic signature. The blank model letter offered for download on the same page prints the words «Firma a mano», sign by hand, under the name line. Electronic in the instructions, handwritten in the template.

Read together, the six files are twenty years of the move from paper to file, frozen in place. There is no single official method — which is exactly why none of the three practical methods can be wrong.

Where the signed file actually ends up

Before deciding how the signature should look, it is worth knowing who receives it. For every active advert in our index we looked at where its application link points. In 33.2 percent of cases the destination address carries part of the advertising employer's own name. In 34.5 percent it belongs to a provider that collects applications for many employers at once. In 18.3 percent it is a job board or a staffing agency. The remaining 14.0 percent could not be classified with confidence, and that group includes cantonal administrations, hospitals and universities whose portals do not repeat their name in the address.

The destinations are also strikingly fragmented. The ten most frequent together account for only 32.0 percent of adverts, the fifty most frequent for 50.7 percent, and about 4.9 percent of adverts point at an address that occurs nowhere else in our index. Applying broadly does not mean uploading to two or three familiar providers; it means uploading to a long tail of unfamiliar ones.

Only 38.5 percent of destination addresses end in .ch. Another 38.1 percent end in .com, 11.7 percent in .jobs and 3.4 percent in .io. A domain ending says nothing about where a file physically sits, but it does say something about how international this market is, and it undercuts the assumption that a Swiss application stays inside Switzerland.

That is not an argument against signing. It is an argument for proportion: your signature image sits on the same page as your address, your phone number and your date of birth, and is no more sensitive than they are. If you would still rather not scatter a scan, the handwriting typeface is a solution with an official precedent behind it.

One rule per channel

Attached PDF, whether emailed or uploaded: sign it. The signature belongs between the closing greeting and your typed first and last name, at roughly the height of one line, and it never replaces the typed name — it sits above it.

Letter written into the body of an email: no signature. Images in email bodies arrive unreliably and are often stripped, so close with the greeting, your name, your phone number and your email address. The signed version travels as the attachment.

Free-text field in an applicant portal: no signature, because there is nowhere to put one. Some portals offer a «cover letter» box that accepts plain text; others require an uploaded document. Write the letter without the three closing lines in the first case, and upload the PDF that has them in the second.

Printed application: sign by hand, after printing, in dark ink. Postal applications have become rare but not extinct — the careers service still lists sending by post as one of its three dispatch routes alongside online forms and email. Where paper is asked for, a handwritten signature is the one form that needs no explanation.

Making a signature image that looks like yours

Sign three or four times across a sheet of white unlined paper with a dark pen, larger and slower than usual. Photograph the sheet from directly above in daylight and pick the version that looks most like an ordinary day rather than the most decorative one. A signature that looks generated is conspicuous for exactly that reason.

Crop tightly, remove the background and save it as a PNG with transparency. Place it at about one line in height; anything larger unbalances the closing block. Keep the typed name underneath, because that is the line that gets read when an image fails to render or the document is processed onward.

Two habits are worth keeping. Use the file for applications only, and store it where the rest of your application documents live. And keep it out of correction tools: the careers service advises removing personal details before pasting text into an AI assistant and not uploading confidential documents at all, which describes a signed letter precisely. Proofread the unsigned draft, sign the final file.

If none of that appeals, remember what the official examples do. The letters Swiss pupils are given as the model contain no image whatsoever — just a name in a handwriting face, above the same name typed plainly.
