- PEPPOL BIS 3.0 (UBL)
Routing & delivery
Common identifiers

Mandate & scope
Denmark combines OIOUBL and NemHandel with PEPPOL-style structured routing for many invoice flows.
Country-specific operating notes for Denmark
Use these points as the practical checks for this section.
- Denmark routes public-sector e-invoices through NemHandel and related eDelivery infrastructure; OIOUBL and Peppol BIS are the key operational formats.
- OIOUBL is a Danish UBL-based profile with its own customization and profile identifiers, so generic UBL output is not enough without Danish CIUS validation.
- Use the correct recipient identifier, such as an EAN/GLN where required, and handle invoice responses or rejection messages as part of the workflow.
Quick checklist
Use these points as the practical checks for this section.
- Public-sector delivery often depends on NemHandel-compatible structured data.
- CVR number and VAT ID should match the supplier record used by the recipient.
- Recipient-specific process/profile settings matter for successful delivery and validation.
How to send (practical steps)
Follow this sequence as the practical checklist for this section.
- Confirm whether the recipient expects NemHandel, PEPPOL, or both.
- Collect the routing identifiers and supplier registration data required for the target channel.
- Generate the invoice in OIOUBL or PEPPOL BIS 3.0 UBL as requested.
- Validate, send, and retain the delivery receipt or acknowledgement.
Validation & compliance
Use these points as the practical checks for this section.
- Check endpoint and participant schemes before routing.
- Validate VAT codes, totals, unit codes, and payment data.
- Use allowance/charge structures instead of negative invoice lines for discounts.
Common pitfalls
Use these points as the practical checks for this section.
- Wrong endpoint or participant scheme for the chosen channel.
- Missing or inconsistent CVR data in supplier setup.
- Using free-text tax descriptions instead of the required codes.
