Classification Equivalents

ISIC 2399 corresponds to NACE 23.91  and NACE 23.99  in the European NACE Rev. 2.1 classification. This ISIC class maps to multiple NACE classes because NACE subdivides the activity at a finer level.

About partial correspondence: A “≈” symbol indicates an imperfect mapping. The ISIC and NACE codes do not share identical boundaries — activities covered here may partially overlap with adjacent classes in the other system.
