What is a Leitweg-ID?

Leitweg-ID routes e-invoices to the correct German public authority mailbox.

The Leitweg-ID (Buyer Reference) is a structured identifier required on XRechnung invoices to German public buyers. It encodes authority, department and optional sub-address segments.

Wrong Leitweg-IDs cause rejection at submission portals. Tentaco includes a Leitweg-ID validator to check format before you send XML.
