The buyer reference is basically made up of three components:

  • Basic address,
  • Specific address and
  • Check digit.

The basic address is used to distinguish whether the invoice recipient belongs to the Federal Administration or to a federal state:

  • 991: The invoice recipient is part of the direct Federal Administration or a constitutional body and receives electronic invoices via the ZRE.
  • 992:
    • a) The invoice recipient is part of the direct Federal Administration and receives electronic invoices via the OZG-RE.
    • b) The invoice recipient is a federal state that receives electronic invoices via the OZG-RE.
  • 993: The invoice recipient is part of the direct Federal Administration and receives electronic invoices via its own solution (neither ZRE nor OZG-RE).
