Swisscom Sign – your electronic signature

Swisscom Sign is more than a digital signature. The qualified electronic signature (QES) is equivalent to a handwritten signature under Swiss law and is valid within the entire jurisdiction of Switzerland. With a QES, you can sign documents electronically, with legal effect, which would previously have been signed by hand (simple written form).

If you need to sign a document that falls under European jurisdiction, please choose our eIDAS-compliant QES.

To be able to digitally sign your documents with Swisscom Sign, you will need:

• A smartphone
  
• My Swisscom App 
• Successful identity check with a valid passport
  

We charge CHF 2.40 per signature. You can pay for this via your Swisscom bill (Swisscom Pay) or by credit card, debit card (PostFinance) or TWINT.

The advantage to you is that you only pay for what you need. You don’t have to buy any packages or subscriptions and are not tied into a contract.

You can invite someone to co-sign a document. It’s simple:

1. Position the signature field for the person to sign the document.
2. Pay for the extra signature.
3. The invited person will receive an e-mail with the link to our website. They then scan the QR code with their smartphone and access the document.
4. If the invited person is not yet registered, they will first need to verify their identity using their biometric ID.
5. The invitee signs the document.
6. You will receive a confirmation e-mail that the signing process has been completed and that the document is ready for download.

Your signed documents will be automatically deleted after the signing process is completed (30 days). You should therefore download the document and save it to your device or the cloud before this.

If you have been invited to sign a document, you can download the signed document again within 30 days. To do this, click on the link you received by e-mail.

On this Swiss Confederation web page, you can upload a document and check for free whether the qualified electronic signature is valid.

Validate document

Yes, thanks to add-ons for Microsoft Office (e.g. Word) and Google Docs, you can digitally sign your documents in a familiar environment.

There will soon be a dedicated Swisscom Sign service for small and medium-sized enterprises (SMEs). For more complex or specific projects, Swisscom Trust Services has a selection of services for Switzerland and Europe. 

A scanned signature does not meet the requirements for a qualified electronic signature. So if you sign on a piece of paper, scan it and use it digitally, it is not legally equivalent to your handwritten signature, because it is easy to fake or reproduce.
