Trusted profile and electronic signature. How are they different?


Each application submitted to state authorities via the Internet, e.g. to the tax office, to the Social Insurance Institution (ZUS) must be signed. Many matters can be dealt with online, using a trusted profile or qualified electronic signature. So what is the difference between an electronic signature and a trusted profile?

Definitions, or what is what?

Trusted profile (eGo) - is a signature confirming identity (assigned to a specific PESEL number) in online contacts with offices. This is a non-commercial product.

ePUAP - is an electronic platform for public administration services through which citizens can deal with official matters via the Internet.

Having an account on the ePUAP platform is not required to set up a trusted profile.

Electronic signature - data (identifying a specific person) in electronic form, which serves as a signature equivalent to a handwritten signature. This is a commercial product.

Qualified electronic signature - an advanced electronic signature that is created using a qualified electronic signature creation device and is based on a qualified electronic signature certificate.

Trusted profile and electronic signature - what's the difference?

Both the electronic signature and ePUAP are signatures that confirm your identity. The main advantages of having e-signatures include the possibility of settling a given matter at any time. So what is the difference between an electronic signature and a trusted profile?


The trusted profile is used only in dealing with official matters online (e.g. via ePUAP ,, PUE ZUS, - i.e. on official platforms.

A qualified electronic signature has a wider application, because it can be used to both settle official matters and, for example, sign some computer documents (eg PDF, WORD) or e-mails.


Trusted profile is free.

A qualified electronic signature is payable.


A trusted profile is valid for 3 years. After this time, you can extend the validity of a trusted profile free of charge.

A qualified electronic signature is valid for 1 or 2 years. After this time, you can extend its validity for a fee (the fee is lower than when buying an electronic signature).

Regardless of the differences, it makes sense to have one of the "online signatures": be it an electronic signature or a trusted profile. The advantages of this solution include:

  • the possibility of settling matters not only from 8.00 to 16.00, but 24 hours a day,

  • no need to appear in person at the office,

  • saving time (for travel to offices), money (for paper printouts, shipping) and nerves (while standing in a queue).

A trusted profile can also be set up in its entirety without leaving your home - for this purpose, the confirmation of the application should be signed with a qualified electronic signature or via electronic banking, at banks that offer the service of creating a trusted profile.

The information contained in a trusted profile includes, first of all, name, surname, e-mail address, PESEL number and user ID, i.e. login.

Establishing and using a trusted profile is free of charge and is valid for 3 years from the date of signing the application. After this period, you can extend the validity of the trusted profile.
