Mobile phone signature

The mobile phone signature is an electronic signature for which you use your mobile phone. This turns your mobile phone into a virtual ID online and you can use it to digitally sign documents or invoices. Electronically signed documents have the same legally validity as documents signed on paper. The mobile phone signature can save you time-intensive trips to the authorities. At the same time, it protects users from unauthorized data changes or third-party access.

Please note

To activate your mobile phone signature, we have to verify your Österreichische Post account at a postal branch. Online verification is not available for this service.
