OASIS-ICD-LIST

The official code list maintained by OASIS that lists every ISO 6523 identification scheme — the shared reference of EN 16931 and PEPPOL.

Definition

The OASIS ICD list (sometimes EAS — Electronic Address Scheme) is the operational code list of the party identifier in European e-invoicing. It codifies each party-identification registry under a 4-digit ISO 6523 prefix (Information technology — Structure for the identification of organizations and organization parts). Some reference values:

• 0002 — System Information et Repertoire des Entreprises et Etablissements (France, SIRET/SIREN)
• 0007 — Organisationsnummer (Sweden)
• 0009 — SIRET-CODE (France)
• 0037 — National Trade Register Identifier (Finland)
• 0060 — Dun & Bradstreet D-U-N-S Number
• 0088 — EAN Location Code (GS1 GLN)
• 0096 — DANISH MINISTRY OF JUSTICE (CVR)
• 0106 — Association of Chambers of Commerce of the Netherlands (KvK)
• 0184 — Danish CPR
• 0192 — Norwegian Organization Number
• 0204 — Leitweg-ID (Germany B2G)
• 9906 — Italian VAT-Number (IT:VAT)
• 9914 — Austrian VAT (AT:VAT)

The list contains over 100 entries in 2026 and keeps growing as countries enable PEPPOL e-invoicing.

Origin

ISO 6523 (published 1984, refactored 1998) defines the general structure of a 4-digit ICD identifier + national identifier. Initial operationalisation was driven by the European project eSENS (e-Sense Network of Services, 2013-2017) which published the exhaustive list. The list was then adopted by PEPPOL and OASIS as the official reference in BDX specifications (BDX-Location, BDX-Identifier, AS4 PEPPOL profile). OpenPEPPOL today maintains an active subset as PEPPOL Policy 21 — Use of identifiers, closely aligned with the OASIS ICD list.

Example in context

A PEPPOL BIS Billing 3.0 invoice sent from France to Belgium typically carries:

Reading: the schemeID is precisely the OASIS list ICD value — 0009 for French SIRET, 9925 for Belgian VAT. Every PEPPOL Access Point reads these codes to perform the SML/SMP lookup and route.
