Nemhandelsregisteret (NHR)

About

Nemhandelsregisteret (NHR) is operated by Erhvervsstyrelsen as the registry backing NemHandel, Denmark's mandatory e-invoicing infrastructure. It maps a recipient identifier — typically a CVR number, GLN/EAN number, or Peppol participant ID — to the endpoints and document profiles (Peppol BIS, OIOUBL) that recipient can receive. As of the 2022 Bookkeeping Act, Danish businesses using digital bookkeeping systems must be able to send/receive structured e-invoices via NemHandel. The registry is migrating to the eDelivery-based NHR API alongside the existing NHR WEB lookup UI.

Agent Use Cases

• 01Look up which e-invoice profiles a Danish counterparty can receive before sending
• 02Validate a CVR number is registered for NemHandel before an ERP integration goes live
• 03Support Bookkeeping Act compliance checks for e-invoicing readiness

Notes

Public lookup via NHR WEB; the dedicated NHR search API is rolling out as part of the eDelivery migration and has had recent breaking changes to its JSON response shape — check nemhandel.dk for the current schema before integrating. Registration as a sender/receiver requires OCES organisation certificates.
