The European Commission is happy to announce the publication of a registry of supporting technical artefacts to implement the European standard on eInvoicing (EN 16931).

This registry provides you with direct access to the different technical resources (validation artefacts, code lists, etc.) to be used in eInvoicing implementations when using the eInvoicing standard.

You can access the following via this registry:

• The European standard: this standard addresses the proliferation of different standards in Europe;
• Validation artefacts: the European standard defines rules to check that an invoice complies with the standard. These rules are expressed in technical validation artefacts. You can use these technical artefacts to automatically validate whether an invoice complies with those rules;
• Code lists: the European standard defines which code lists may be used for each business term that has the data type "code", such as electronic address, VAT number, currency, etc.. The European Commission is managing authority for the VAT and electronic address, code lists. All other code lists are managed by European Committee for Standardization (CEN);
• Core invoice Usage Specifications (CIUS) and Extensions: buyers who must support specific processes or legal requirements may need to restrict, or extend the European standard's core data model. You can use a CIUS to help mitigate this;

You can also submit requests for change to these technical resources via this registry. Such change requests are essential to ensure these technical artefacts evolve to suit market need and the Commission invites all stakeholders to actively contribute to the development to these artefacts. 

The items in this registry will be updated when necessary. The Commission warmly invites you to register on the dedicated page in the eInvoicing User Community to receive automatic email notifications for updates to these technical artefacts.

The Connecting Europe Facility (CEF) eInvoicing Building Block aims to promote the successful uptake of electronic invoicing in Europe, respecting the European standard on electronic invoicing and Directive 2014/55/EU on electronic invoicing in public procurement.

Best regards,

The CEF eInvoicing team
