Information to be provided / made available by ASPSP to payment initiation service provider (PISP)

a) Article 66(3)(f) PSD2 states that payment initiation services (PIS) providers shall not request from the payment service user any data other than those necessary to provide the payment initiation service. It follows from this provision that the account servicing payment service provider (ASPSP) is only required to provide or make available the information necessary for the provision of the PIS. As it is always the payment service user that specifies the account the transaction shall be initiated from, there is no need for the ASPSP to provide or make available to the PIS provider a list with all the account numbers of the payment service user and the associated currencies, as long as this would not create obstacles for the provision of PIS as per Article 32(3) of the Commission Delegated Regulation 2018/389 . b) Q&A  2018_4081  sets out that ASPSPs shall provide or make available the name of the Payment Service User (PSU), if it is necessary for the provision of the PIS or the account information service. *As of 10/05/2019 a clarification was added to this answer where the new text is underlined.   Disclaimer: This question goes beyond matters of consistent and effective application of the regulatory framework. A Directorate General of the Commission (Directorate General for Financial Stability, Financial services and Capital Markets Union) has prepared the answer, albeit that only the Court of Justice of the European Union can provide definitive interpretations of EU legislation. This is an unofficial opinion of that Directorate General, which the European Banking Authority publishes on its behalf. The answers are not binding on the European Commission as an institution. You should be aware that the European Commission could adopt a position different from the one expressed in such Q&As, for instance in infringement proceedings or after a detailed examination of a specific case or on the basis of any new legal or factual elements that may have been brought to its attention.
