The Regional Offices monitor credit institutions and financial service providers in their respective regions. The branches are subordinate to the Regional Office and supply the economy with euro banknotes and coins.

The denominations of euro banknotes embody the shared theme of "Ages and styles of Europe" and represent the architectural styles of seven periods of European cultural history. They have been legal tender in all of the participating European Union member states since 1 January 2002. In addition, the physical appearance of euro banknotes is identical throughout the euro area. The European Central Bank and the national central banks of the Eurosystem began rolling out a second series of euro banknotes in May 2013.

As agreed with the central associations of the German banking industry, the bank sort code files will be updated on a quarterly basis on the Monday following the first Saturday in March, June, September and December.
