The Zentrale Stelle Verpackungsregister (Central Agency Packaging Register – ZSVR) includes experts, auditors, tax advisers and sworn accountants who indicate to the ZSVR their intention to conduct the audits provided for by the Verpackungsgesetz (Packaging Act) in a register of auditors, and publishes this register on the internet.

Experts must register individually for technical reasons; it is not possible to register organisations of experts. The essential registration requirements are set out in section 27 VerpackG. In addition to the master data needed for registration, suitable evidence of the auditor's professional certification is required. This has to be uploaded during the registration process. It is not sufficient to upload an authorisation for a firm of auditors; documentation for a specific auditor is required. Once the information and the evidence has been verified by the Zentrale Stelle Verpackungsregister (Central Agency Packaging Register – ZSVR), the registration will be approved. This may take a few business days to complete.
