Every business registered on the Peppol network has an Endpoint ID. When you send a Peppol invoice, the sender's Access Point looks up the receiver's Endpoint ID in the SMP (Service Metadata Publisher) to find their Access Point and deliver the document.
Structure
Endpoint ID = Scheme ID + Identifier Value
Examples:
0208 + KBO/BCE number 01234567890106 + KvK number 123456789930 + USt-IdNr DE123456789In UBL XML
The Endpoint ID appears in both sender and receiver party elements:
0123456789
12345678
Registration
Endpoint IDs are registered through your Peppol Access Point provider. The Access Point registers your business in the SMP, making you discoverable on the network.
Common Issues
Missing endpoint ID — every Peppol invoice must include the buyer's Endpoint ID. If your ERP doesn't have the buyer's Peppol registration details, the invoice can't be routed.
Wrong scheme ID — using scheme 9930 (German VAT) for a Belgian business that should use 0208 (KBO/BCE) will cause routing failures.
