Required documents

The verification process and the documents required when purchasing:

The Certum E-mail ID Individual certifiacte

Certum E-mail ID Individual certificates are issued automatically based on the Subscriber’s demonstrated control over the e-mail address. Certum does not require any additional documents from the Subscriber.

The verification of access to the e-mail address consists in clicking on the verification link, which is sent during certificate activation to the e-mail address indicated by the customer.

In justified cases, the Certum Team may ask for sending additional documents necessary for proper verification.

The Certum Email ID Business certificate

In order to activate the Certum Email ID Business certificate, in addition to verification of the e-mail access, it is necessary to verify the identity of the Subscriber (person applying for the certificate). The method of verification is selected during certificate activation.

Verification based on documents

This method consists in sending the following documents:


  • notarial confirmation of identity

or for a quicker issuance

  • a copy of the identity document of the ordering person (ID card, passport, driving license, permanent residence card). The copy should be a fully reproduced document (both sides).

The identity can also be confirmed on the basis of a valid qualified certificate issued for the Subscriber by Certum.
We would like to inform you that if you choose the option of a copy of the identity document, this copy will be used only for the purpose of processing the contract/order and after confirmation of your identity will not be further processed and will be immediately, permanently deleted from our database.

  • additionally, also a power of attorney, authorization or employment certificate for the person whose data is to be included in the certificate is required – if such person represents the entity whose name is to appear in the field Organization.
