The Central Bank of Ireland's registers (http://registers.centralbank.ie/) record the credit institutions authorised under Irish legislation to carry on banking business in the State, and those credit institutions authorised in other Member States of the European Economic Area (EEA) to carry on business in the State without receiving further authorisation from the Central Bank of Ireland, pursuant to the terms of the EU Directive, 2013/36/EU relating to the taking up and pursuit of the business of credit institutions.
The Central Bank does not maintain a record of the number of bank branches in the State.
