CZ-NACE converter 2008 → 2025

Enter an original CZ-NACE 2008 code to see the matching 2025 codes. The new revision can split one activity across several codes (a 1:N mapping); the tool never picks a single one for you. This is the Czech classification, not a Slovak one.

A section A–U or 2–5 digits, with or without dots. Five-digit national codes are never converted by guesswork.

How do you convert a CZ-NACE code?

Enter a code from the 2008 revision. The Czech Statistical Office converter lists the possible matching 2025 codes. With a 1:N mapping the actual activity decides; even a single mapping does not guarantee identical scope.

CZ-NACE 2008 is based on NACE Rev. 2; CZ-NACE 2025 on NACE Rev. 2.1. The Office states the new revision applies from 1 Jan 2025 and was introduced in the RES register on 1 Jan 2026. We use the corrected Czech names from December 2025.

What code does a company have?

Open a Czech company profile using a Czech IČO only. A valid checksum does not establish company existence or assign CZ-NACE to that company; this is not a Slovak registry lookup.

Method, sources and limits
  • Levels 1–4 use the European converter V1.05; explicit national subclasses use the Czech five-digit converter.
  • The 2025 Czech names come from the corrected systematic part 202512. It is an administrative catalogue; its wording does not by itself confirm conformity with legislative titles.
  • Where an exact national correspondence is missing, we offer only a separate conversion of the parent four-digit class. A national code is never derived from it automatically.
  • JSON is derived: sheet selection, code normalization and grouped correspondences; it is not unchanged official Czech Statistical Office statistics.
  • The code or text you convert or search for stays in your browser. After a local check, the IČO is placed only in the link to the Czech profile; network navigation happens only after you click. No input is stored.
  • Catalogue names and explanations remain in their original source language.
