Verification process and required documents

The verification process and documents required after purchasing a Certum E-mail ID Certificate

The Certum S/MIME Mailbox

Certum S/MIME Mailbox 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 S/MIME Individual, Sposnor, Organization

In order to activate below certificates, 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.
