(1) In the context of the European Maritime Single Window environment established by Regulation (EU) 2019/1239, declarants and data service providers (senders) can fulfil their reporting obligations via a system-to-system connection to the reporting interface module (RIM) of the maritime national single windows (MNSW).

(2) The RIM, developed in accordance with the specifications laid down in the Commission Implementing Regulation (EU) 2023/2790 (2) ensures technical interoperability and the use of a harmonised set of messages for data exchange with the MNSWs. Before senders exchange data with MNSW through the RIM, the connection details have to be manually configured. This is also required in the case connection details change. The common addressing service should overcome this issue by way of facilitating the automatic configuration of the direct system-to-system connection.

(3) The common addressing service should use dynamic discovery that ensures flexibility and scalability to the network of MNSWs. Senders should be able to use the common addressing service to initiate direct system-to-system data connection between their AS4 access point and a RIM by way of automatically retrieving the latest connection details of a RIM.

(4) The common addressing service should minimise the need for human interventions and should, therefore, proportionally reduce costs and risks of errors, making the network flexible when there is a change in connection details of its participants, such as endpoint information and public certificate.

(5) To ensure interoperability and reduction of implementing costs, the common addressing service should be based on the same technologies and standards used for the RIM.

(6) The central locator node should contain participants’ identifiers and the publisher nodes location, and it should be hosted centrally to ensure that such data is kept up to date in the public Domain Name System (DNS).

(7) To enhance the resilience of the service and mitigate the risk of a single point of failure, each Member State should host its own publisher node that should contain all necessary connection details of the corresponding RIM.

(8) To ensure scalability and flexibility also to the authorities of the Member States managing the MNSWs, Member States should also be able to store in their publisher nodes the connection details of the AS4 access points of senders, in alternative of manually pre-configuring those in their RIM.

(9) To make its publisher node discoverable to common addressing service users, to ensure the correctness and availability of the publisher node address in the public DNS and to prevent common addressing service users in discovering de-commissioned or non-existent publisher nodes, Member States should be able to register, update and delete its publisher node details through the central locator node.

(10) The Maritime National Single Windows constitutes a cross-border digital public service in the meaning of the Regulation (EU) 2024/903 of the European Parliament and of the Council (3) (‘Interoperable Europe Act’). This Regulation introduces new binding requirements affecting the aforementioned digital public service(s), and, as such, is subject to the interoperability assessment obligation under Article 3 of the Interoperable Europe Act. Accordingly, an interoperability assessment has been carried out, and the resulting report is to be published on the Interoperable Europe Portal,
