E-Invoice ValidatorLeitweg-ID
The German routing identifier for invoices to public clients.
The route ID is a character string assigned by the public client that determines the route of the invoice through the administration. It is in BT-10.
It is not a tax number or an order number, but rather routing information - comparable to a zip code for invoices.
XRechnung requires it via rule BR-DE-15. Anyone who invoices for authorities receives them from the client.
