Digital Signatures & Seals

Electronic seals for public authorities and industry

The electronic seal (also known as a qualified electronic seal under eIDAS, or ‘qSeal’ for short) is the digital equivalent of the traditional company stamp, which is still in use in many places. As a qualified trust service provider, we are authorised to issue legally valid electronic seals for you in accordance with eIDAS.

Below, you’ll find everything you need to know about the electronic seal: how it differs from an electronic signature, its benefits, use cases and how to apply for one.

If you need a qualified electronic seal for EPREL or the digital product passport, you’ll also find the relevant information here.

Electronic seal vs. electronic signature

What are the differences?

Whether it’s a contract, an invoice or an official notice: often, it’s not just a matter of sending a document, but of ensuring that recipients can immediately recognise who it comes from and whether it has been altered. This is precisely what digital signatures and digital seals are for – two terms that are often confused in everyday use, but which serve different purposes.
The table below gives you an overview of the key differences between electronic seals and electronic signatures.

Advantages of the electronic seal

Faster processes

Documents can be sent directly from the system without the need for a manual signature.

Greater traceability

The seal is verifiable and supports audits, as its origin and integrity can be transparently verified.

High scalability

Even large volumes of parcels can be handled reliably without a corresponding increase in staffing costs.

Consistent output

Every document is stamped in accordance with the same standard – regardless of the individual, team or location.

Our electronic seal solutions:

Signing portal

In our signing portal, you can sign documents electronically directly in the cloud. All you need is a device with a web browser; there’s no need to download any software.

signing APIs

With our signing APIs, you can integrate electronic seals directly into your applications and processes. This allows you to seal documents automatically – ideal for recurring document types and bulk documents.

signing token

With the signing token, you use the electronic seal locally on your computer – ideal if you deliberately want to work without the cloud or wish to secure fixed workstations.

Trust Center Infrastructure

The Trust Centre infrastructure is suitable if you have particularly high seal volumes or if there are specific security requirements, as the seal certificates are hosted directly within your own server environment.

Once the seal application has been successfully signed, we will issue your seal and notify you by email as soon as it is available. You can then start using your seal.

Do you need a seal for EPREL?

You’re in the right place!

To sell electrical products in the EU, you must first register with the EPREL database. Once you have successfully registered, you must verify your business using a qualified electronic seal (qSeal). During this process, a PDF file is generated which must be downloaded, sealed (or, in the case of sole traders, signed) and uploaded again.

As a qualified trust service provider, we are authorised to issue the required qSeal. The process for applying for the seal is exactly as described above. Once we have issued your seal, you should apply it to the EPREL declaration and then upload the qualified sealed PDF back to EPREL. To ensure you don’t miss anything, we have provided step-by-step instructions for EPREL sealing in our Help Centre. You will also find a YouTube video there that walks you through the entire process.

FAQ on the electronic seal

What is an electronic seal?

You can think of the electronic seal as a digital company stamp. It is the equivalent of a physical company stamp. The electronic seal confirms the origin and integrity of a document. In other words, it certifies that this document originates from this organisation and has not been tampered with.

What is the difference between an electronic seal and an electronic signature?

A signature belongs to a natural person. A seal belongs to an organisation (e.g. a limited liability company, a public authority, an association) and confirms the origin and integrity of a document.

What does qSeal (qualified electronic seal) mean?

A qualified electronic seal is the highest level of seal under eIDAS. It is based on a qualified certificate and meets particularly stringent requirements.

What is an electronic seal actually used for in practice?

Typical use cases include notices, certificates, invoices, supporting documents, attestations, data sheets, and documents for portals or registrations (e.g. EU reporting processes).

Is an electronic seal legally recognised?

Yes. Electronic seals are regulated in the EU by eIDAS. Qualified seals carry particularly strong evidential weight because they meet strict requirements.

If you are a public authority wishing to apply for an electronic seal, we first need official confirmation from you. Please fill in the form with your name and email address, and we will send you the form and all the necessary information.
