Order reference of the public sector

The order reference is a technical invoice address and for that an essential part of E-RECHNUNG.GV.AT. The order reference controls the mapping to the correct recipient and the processing of the submitted e-Invoice in the contracting authority system.

The order reference is solely issued by the contracting authority (E-RECHNUNG.GV.AT support as well as the USP hotline cannot give any information) and can be composed as follows:

  • At least a 3 digit alphanumerical value, e.g. Z0/ (recipient identification)
    • The slash at the end is mandatory and must always be contained
    • The invoice lines do not have to contain order position numbers
    • This value automatically links the e-Invoice to the recipient
  • At least a 3 digit alphanumerical value with an additional internal reference, e.g. Z0/internal reference (recipient identification/internal reference)
    • The recipient identification and the internal reference must be separated with a slash ("/") without any whitespace
    • The internal reference can be for instance a reference number, a contract number or an order number
    • The invoice lines do not have to contain order position numbers
    • The recipient identification automatically links the e-Invoice to the recipient
    • The internal reference serves the case worker of the contracting authority to link the e-Invoice to the order. It must not be longer than 50 characters.

Note: for states, cities and municipalities the usage of the so called "Verwaltungskennzeichen" (VKZ) is the proposed recipient identification.
