Digital signature Austria: eIDAS-compliant electronic signature
actaSIGN is the signature platform for Austrian businesses that want to sign contracts electronically and digitally with legal validity. The solution supports SES, AES and QES under eIDAS, respects the Austrian trust-services framework, and combines Swiss hosting with DMS integrations for the Austrian market.
Short answer
Is a digital or electronic signature legally valid in Austria?
Yes. In everyday use, digital signature and electronic signature are often used synonymously; legally, the eIDAS Regulation distinguishes simple, advanced and qualified electronic signatures.
SES and AES can be used for many form-free contracts. Where written form must be fulfilled electronically, the qualified electronic signature (QES) is the right signature level.
actaSIGN uses Swisscom Trust Services and supports eIDAS-compliant signatures for Austrian businesses, including cross-border contracts with Switzerland and Germany.

Legal framework for electronic signatures in Austria
As an EU member state, Austria is subject to the eIDAS Regulation. The Signatur- und Vertrauensdienstegesetz (SVG) complements the framework.
eIDAS Regulation
The eIDAS Regulation defines three signature qualities and applies directly in all EU member states. It ensures cross-border recognition of electronic signatures.
SVG — Signatur- und Vertrauensdienstegesetz
The Austrian Signatur- und Vertrauensdienstegesetz (SVG) complements the eIDAS framework. RTR (Rundfunk und Telekom Regulierungs-GmbH) maintains the Austrian trust list and provides signature verification services.
Freedom of form in Austrian law
Austrian law generally provides freedom of form. Most contracts can be concluded with EES or AES. For contracts with statutory written form requirements (e.g. under ABGB), QES is the legally secure solution.
Which signature level fits in Austria?
The right signature level depends on risk, evidentiary need and possible written-form requirements.
| Signature level | When sufficient? | When QES? | Typical examples |
|---|---|---|---|
| SES — simple electronic signature | For simple, form-free approvals and low-risk processes. | Not suitable where a handwritten signature must be replaced electronically. | Internal approvals, simple confirmations, acknowledgements of receipt. |
| AES — advanced electronic signature | For many form-free contracts with higher evidentiary needs. | Not sufficient where statutory written form with handwritten signature is required. | NDAs, supplier contracts, service agreements, HR documents. |
| QES — qualified electronic signature | When maximum evidentiary value or a statutory written-form requirement is relevant. | Replaces a handwritten signature within the eIDAS framework. | High-value contracts, selected HR and compliance documents, cross-border agreements. |

Digital signature or electronic signature — what's the difference?
In Austria the terms are often used interchangeably. Legally relevant under the eIDAS Regulation and SVG is the "electronic signature" with its three quality levels (SES, AES, QES). A "digital signature" strictly refers to the underlying cryptographic technique. For legal validity, what matters is the signature quality, not the wording.
