Article 4 — Establishment of cross-border coordination points

1. Member States may establish, on the basis of their institutional and legal framework, one or more cross-border coordination points at national or regional level in accordance with paragraphs 2 and 3. Where a Member State decides to establish one or more cross-border coordination points only for some of its border regions, it shall not be required to establish cross-border coordination points for its other border regions. Where a Member State has both land and maritime borders with another Member State and decides to establish one or more cross-border coordination points, it shall not be required to establish a cross-border coordination point for any of its maritime border shared with that Member State. 2. Two or more neighbouring Member States may decide to establish a joint cross-border coordination point competent for one or more of their cross-border regions. 3. Where a Member State decides to establish one or more cross-border coordination points, each cross-border coordination point shall be established either as: (a) a part of an existing authority, public law body or permanent entity, including by entrusting that authority, public law body or permanent entity with the additional tasks of the cross-border coordination point; or (b) a separate authority, public law body or permanent entity. 4. Member States shall ensure that, within two months of the adoption of a decision establishing a cross-border coordination point, its contact details and information relating to its tasks: (a) are made available on the website of the authority, public law body or permanent entity that has been established as a cross-border coordination point and on the websites of the relevant Interreg A programmes referred to in Article 36(2) of Regulation (EU) 2021/1059; and (b) are at the same time transmitted electronically to the Commission in accordance with the Annex to this Regulation. Member States shall ensure that those contact details and information are kept up to date. Member States shall ensure visibility and accessibility of the cross-border coordination point.
