# Austria e-Rechnung.gv.at Peppol Invoice

Source: https://xmlvalid.com/schemas/at-erechnung-peppol-invoice

> A Peppol BIS Billing 3.0 invoice to the Austrian federal government, checked against UBL 2.1, the EN 16931 and Peppol rules and what e-Rechnung.gv.at requires on top.

e-Rechnung.gv.at receives invoices to the federal government over Peppol under one participant ID for all of them (9915:b) and finds the office the invoice is for from its order reference. It reads the order reference from the purchase order reference (BT-13) and the supplier number the federal government assigns from the seller identifier (BT-29), and runs its own checks on the invoice besides the Peppol ones.
Those checks run here with the portal's codes: the order reference and its form, the order position of each line (BT-132) when the reference is an order number, the supplier number, the seller's e-mail address, a delivery date or period, the payment means, the IBAN and Austrian VAT numbers.
