About this conversion
WZ 2025 is the activity classification used in Germany. NACE Rev 2.1 is the equivalent system in Ireland. Both are national implementations of EU NACE Rev 2.1, so any 5th-digit subclass in one system can be traced back to a shared 4-digit EU class — and from there, forward into the other country's subclasses.
