EV Code Signing - increased level of customer trust

We do not issue EV Code Signing certificates to natural persons!

To verify the Subscriber's identity CERTUM requires the submission of the following documents:
  1. identity document (ID card, passport, residency card, driving license)- in Latin characters - of the person placing the order. The copy should depict the entire document (both sides),

    If it is not possible to send the following documents (ID card, passport, driving license, permanent residence card) there are few others possibilities to verify your identity:

    • notarial identity confirmation - a document in English language or a document translated into English by the sworn translator
    • identity confirmation at CERTUM’s Registration Point or Identity Confirmation Point
    • possession of the qualified certificate issued by CERTUM

    and

  2. a utility bill (e.g. water, electric power, natural gas, etc.), bank statement, credit card statement, government‐issued tax document belonging to the organization,
  3. company registration documents - only in the case where the company doesn’t possess the DUNS number (it’s impossible to verify the company by using this number or by using national registration number),
  4. authorisation or power of attorney confirming connection of the person submitting the order with the organisation - only when the applicant doesn’t appear in the relevant registry as a person authorized to represent the company

In appropriate cases the CERTUM Team may ask for additional documents necessary for proper verification.
