The Peppol eDelivery Network Specifications

The Peppol eDelivery Network Specifications

This section includes specifications and resources to enable access to the Peppol eDelivery Network and to implement the following components: Access Points, gateways which ensure a standard and solid transport mechanism to exchange different types of documents across different communities or countries; Service Metadata Publishers (SMPs), which contain the exact location and the capabilities of participants; Service Metadata Locator (SML), used to add/update/delete the IDs of the participants, and which offers a DNS-based mechanism to discover the SMP where the specific participant data is described.


In the table below you will find the set of specifications that define the implementation of the Peppol eDelivery Network. Support for these specifications is mandatory (except AS2 which is optional in the Peppol Network).

Peppol Directory

The Peppol Directory is in use for optional use. All SMP providers are encouraged to push Business Card information of their receivers to the Peppol Directory to obtain a higher transparency for all participants in the Peppol eDelivery Network.

Introduction to AS4 as a new transport protocol

In a Letter of Understanding (LoU) signed between the European Commission and OpenPeppol, the parties agree a plan for the transition from AS2 to AS4 as the message exchange protocol in the Peppol profile of CEF eDelivery. The transition is planned to follow three main phases, where AS4 will become mandatory in the Peppol profile of CEF eDelivery from Q2 2019, provided that each phase is successfully completed. The parties have agreed on a list of conditions that need to be proven and tested to ensure a safe migration and will take steps to stimulate a market take-up of this migration plan.

The agreed transition includes the introduction of the AS4 protocol in the Peppol eDelivery Network for optional use from 2017. In the Pre-Award domain, use of the AS4 message exchange protocol is mandatory due to an agreement made with e-SENS. Currently the OpenPeppol AS4 Transition Workgroup is preparing a Peppol profile of the CEF/e-SENS AS4 implementation to clearly specify how AS4 is to be used in the Peppol eDelivery Network. This new profile will be well aligned with the CEF/e-SENS AS4 profile and based on the experience gained during the e-SENS eTendering pilot.


Peppol Transport Infrastructure Agreements (TIA):

Transport Infrastructure Agreements (for sample purposes only). You can obtain the appropriate set of agreements from your national Peppol Authority.

Please see the list of Peppol Authorities in the ‘Who is who’ section of our website for further information at a national level and their representatives to contact for obtaining and signing the Peppol Transport Infrastructure Agreements (TIA).

You can sign the TIA with the Peppol Authority in the country where your business is registered. Alternatively, if there is no Peppol Authority in your country, you could sign the TIA with OpenPeppol as the Authority and re-contract at a later date when an Authority is established nationally. In this case, please contact to obtain the appropriate agreements.


Peppol Transport Infrastructure – implementation support:


CEF e-Delivery
The Directorate-General for Informatics of the European Commission maintains a sample implementation of OpenPeppol’s eDelivery Network. This implementation aims at providing a generic solution for public administrations to exchange documents in a secure, reliable and trusted way. The CEF e-Delivery solution provides the following components: Access Points, Service Metadata Publishers (SMPs) and Service Metadata Locator (SML).
