About this conversion

CAEN Rev. 3 is the activity classification used in Romania. ATECO 2025 is the equivalent system in Italy. 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.
