I. Registration. Users Profile

1. Is registration possible without a qualified digital signature?

A qualified digital signature is required whenever a contracting authority/entity, an economic operator or a physical person would like to register by using the public page of CAIS EOP. The registered organization’s administrator sends by e-mail invitations to organization’s employees in order to register. A qualified digital signature is not required in this case.

2. When a legal entity is at the same time a contracting authority/entity and an economic operator, in what role should it first register?

7. How do divisions register? Does it matter what registers first – the division or the headquarter?

Divisions register the same way as headquarters do. It does not matter whether the headquarter or the division registers first. CAIS EOP recognizes the unique identification code (UIC) of the division/headquarter and when a registered headquarter/division is present, it automatically creates a division-headquarter connection, respectively a headquarter-division connection.
