However, more extensive information about the companies is subject to restrictive regulations. Therefore, registration is required and a special legal interest in the use must be proven. For this purpose, an application for registration must be completed and stamped with the company stamp and sent by post to the City of Salzgitter, Fachgebiet Gewerbe, Joachim-Campe-Straße 6-8, 38226 Salzgitter. The access data will be sent promptly after verification by the authority.

Registration is subject to a fee for lawyers, credit agencies or insurance companies. Administrations, social insurance institutions and employment agencies, on the other hand, are exempt from fees. Among other things, registered users have additional access to companies that have already been deregistered or the names and addresses of managing directors.
