CERTUM QES Certificate
Yes, after purchasing the CERTUM Electronic Signature set or the SimplySign service, you will need to verify your identity. You can do this in one of three ways:
Once the verification process is complete, you’ll be able to activate your electronic signature and start using it.
You do not need to be a holder of a Polish PESEL number to apply for a CERTUM electronic signature. However, you may be required to have this number to be able to send certain documents to the servers of the Polish tax office. Contact with your representatives in Poland to precise information on this requirement.
If you are a member of the management board or a director of a Polish limited company, we recommend applying for a Polish PESEL number before you apply for an electronic signature certificate. This will avoid possible problems in the future and incurring additional costs for a new certificate.
Certum Electronic Signature Certificates are valid for one, two, or three years. In most cases, the certificate’s validity period is linked to the expiration date of your passport. Please contact us for detailed information.
The differences between Certum Standard, Certum Mini, and SimplySign mainly concern the method of use and the type of device used:
The choice depends on your needs – if you mainly sign documents on a computer, a hardware set may be a better option. If you prefer a modern and mobile solution, SimplySign will be the best choice.
