Is this the official NAF → WZ mapping?

Yes. Both classifications are anchored on NACE via the correspondence tables published by Eurostat and the national statistical institutes (the national institute for NAF, the national institute for WZ). We surface those mappings directly.

What revision year does this cover?

The 2025 vintages (NAF aligned to NACE Rev. 2.1 where applicable, WZ aligned to its 2025 national republication). Historic vintages are available on request.

Why does the tool pass through NACE?

NACE is the shared European anchor. Every national classification is defined in terms of NACE, so anchoring cross-country conversions on NACE is how the national statistical institutes themselves resolve them — it's exact, not an approximation.

Can I bulk-convert a spreadsheet?

Yes — the JSON/CSV API accepts arrays of codes and returns the same mapping. See the developer docs for endpoints and rate limits.

Convert a French NAF code to the matching German WZ 2025 class — with example codes, an official mapping, and the reverse lookup one click away.

NAF (France) and WZ (Germany) are both national statistical classifications aligned to the European NACE framework, so every code has a well-defined equivalent on the other side.

This converter reads a NAF code, resolves the matching NACE class from the official correspondence, and returns the equivalent WZ code(s). It's the same result you'd get by looking up both codes side-by-side in the Eurostat RAMON tables.

If a NAF code maps to more than one WZ code (splits happen when national institutes disagree on granularity), we show every candidate so you can pick the right one for your context.
