E-Invoice Code Lists
Quick references for the most common code lists used in EN 16931, XRechnung, and PEPPOL workflows.
This article treats E-Invoice Code Lists as a practical reference, not just a navigation page. It explains the term or workflow in context, shows why it matters for European e-invoicing, and connects the topic to invoice creation, validation, routing, archiving, and ERP implementation decisions.
Use lists in real workflows
Pick the list your invoice profile requires, map codes in your ERP or integration, then validate the assembled file. Wrong codes are a frequent KoSIT/PEPPOL rejection reason.
