Company, certificate and authorisation

These are three separate checks. The right company and a valid certificate still require UJP authorisation.

Checked on 6 September 2026

1. Add the company using the correct EDB and verify its details.
2. Select the signing person’s certificate in the local application.
3. If access is denied, check the authorisation with UJP. Reinstalling the extension will not grant access.
4. An invo.mk collaboration invitation does not replace UJP authorisation. Never use another person’s PIN or certificate.
