Summary

• Central e-invoicing directory: ELMA is Norway’s official electronic address registry that identifies which businesses can receive structured e-invoices and how to route them. [ec.europa.eu]
• Core to Peppol infrastructure: It enables automated document exchange (EHF/Peppol) by providing recipient capabilities and access point details for seamless interoperability. [edicomgroup.com]
• Mandatory for receiving e-invoices: Registration in ELMA is required for entities (especially in B2G and Peppol flows) that want to receive electronic invoices in Norway. [docs.digdir.no]

ELMA (Elektronisk mottakeradresseregister) is Norway’s electronic address directory for e-invoicing and other structured business documents.

1) Core definition

ELMA is a central registry that identifies which companies can receive electronic documents (especially e-invoices) and how to reach them digitally. [ec.europa.eu], [evidi.com]

• Full name: Elektronisk mottakeradresseregister
• Function: a digital address book for routing invoices and other documents
• Scope: mainly EHF (Elektronisk Handelsformat) / Peppol documents

👉 In simple terms:
ELMA tells the sender “can this company receive an e-invoice and where should I send it?”

2) Role in the Norwegian e-invoicing model

ELMA is a core component of the Peppol-based e-invoicing infrastructure in Norway. [edicomgroup.com], [comarch.com]

• Norway uses the Peppol network to exchange invoices
• ELMA acts as the national Service Metadata Publisher (SMP)
• It stores:
  • recipient identifiers (organisation number)
  • supported document types (invoice, credit note, etc.)
  • routing information (access point)

📌 Result: invoices can be routed automatically without bilateral agreements.

3) How ELMA works (simplified flow)

1. Supplier creates an e-invoice (EHF / Peppol BIS)
2. Supplier’s system queries ELMA (via Peppol lookup)
3. ELMA returns the recipient’s routing details
4. Invoice is delivered via Peppol access points
5. Recipient receives it directly in their system

This enables fully automated, straight‑through invoice processing. [samarbeid.digdir.no]

4) When registration in ELMA is required

• Mandatory for public sector invoicing (B2G)
• Required for any entity that wants to receive Peppol/EHF invoices [edicomgroup.com], [docs.digdir.no]

Key principle:
👉 If you want to receive structured e-invoices in Norway, you must be registered in ELMA.

Additional implications:

• A supplier can only send an EHF invoice if the recipient is listed in ELMA
• Registration means you agree to receive documents in standard format

5) Practical importance for businesses

ELMA provides several operational benefits:

• Automation: removes manual address handling
• Accuracy: validated digital addresses → fewer errors
• Interoperability: aligned with Peppol and EU standards
• Scalability: no need for bilateral onboarding

It is therefore a key enabler of real-time / structured VAT data flows.

6) Forward-looking (relevant for ViDA context)

With Norway moving toward mandatory B2B e-invoicing from 1 January 2027, ELMA will become even more critical:

• businesses must send structured invoices (EHF)
• routing via Peppol (and therefore ELMA lookup) becomes standard
• foreign VAT-registered entities will also be impacted [taxnews.ey.com]

✅ In one sentence:
ELMA is Norway’s official Peppol directory that enables automated discovery and routing of e-invoices by identifying which companies can receive them and where to send them.
