German routing ID required for many public sector recipients (B2G).
Definition
German routing ID required for many public sector recipients (B2G).
Why this term matters
A Leitweg-ID can identify the German public body and internal unit that should receive an invoice. Put the buyer-provided value in BuyerReference (BT-10) when required. Peppol routing uses BuyerElectronicAddress (BT-49). A buyer can separately register a Leitweg-ID there under EAS 0204, so use only the endpoint value and scheme supplied for that route.
Explanation
Used to route XRechnung invoices to the correct authority/department.
Missing or invalid Leitweg-ID often causes rejection.
Common mistakes
- Putting the Leitweg-ID in BT-13 (PurchaseOrderReference) or BT-12 (ContractReference) instead of BT-10 (BuyerReference) — KoSIT BR-DE-15 fails.
- Dropping the optional fine-routing component when the buyer supplied it as part of the required value.
- Reusing a Leitweg-ID from another buyer or department instead of the exact value provided for this order.
- Checking only the visible pattern. The fine-routing component can be empty or up to 30 characters, and the final two checksum digits must also validate.
Frequently asked questions
Where does the Leitweg-ID come from?
Get it from the buyer’s order, tender documents, supplier instructions, or contact person. Do not create or guess it.
Is the Leitweg-ID required for all German B2G invoices?
No universal rule covers every state and municipality. Federal workflows normally require it; other buyers can use different routing references. Follow the recipient’s instructions for BuyerReference (BT-10).
Can I send a Leitweg-ID via Peppol or only via portals?
If the buyer accepts Peppol, put the required buyer reference in BT-10. Set BT-49 separately from the endpoint and EAS scheme supplied by the buyer or network. A buyer may register its Leitweg-ID as that endpoint under EAS 0204, but do not copy BT-10 into BT-49 without this routing information.
