As the world is slowly adapting to a more digital environment, more countries are coming up with solutions for secure digital transactions and verification of identity. Poland is one of those countries, and their solution is the Electronic Platform of Public Administration Services – ePUAP.

What is ePUAP?

The ePUAP was introduced by Polish government in the late 2000’s and is mainly used for public service transactions such as e-tax filing and e-healthcare.

In ePUAP, the user´s secure electronic identity is identified and verified through the online identification and authentication process. After the verification process is completed, the user will be able to perform electronic document signing using the ePUAP system. The signature is a digital code that is tailored to the user’s information and is unforgeable, ensuring the highest levels of security.

What Services Can Be Accessed Through ePUAP?

It’s possible to register a company profile in ePUAP with the help of the private account, and use the ePUAP portal for communication with the administration or signing the documents. 

Additionally, this system is also used to:

  • submit annual tax declarations
  • register for healthcare plans
  • submit many other forms to public institutions.
