For the applicants: Questions about registering, the tendering documentation and the standard form


Can I register more than once with my UID?
No, a UID can only be registered once. If a UID is already in the system, then the company, its contact person and its administrator have already been registered. The company and its administrator will be published in the Directory of bidders.

Why must an email address and mobile telephone number of an administrator be given when registering a bidder?
The email address is for transmitting a link that is used to set the password and the mobile phone number for sending a one-time password that is needed to complete the registration process (2-factor authentication). This method ensures that administrator contact data can be cross-checked and support services rendered.
