NACE Rev. 2.1 manufacturing codes: what changed for industrial account lists

Regulation (EU) 2023/137 sets NACE Rev. 2.1 and its 22 sections, and Eurostat's methodology describes the phase-in from 2025 to 2031.[1][2] Eurostat's correspondence tables map old codes to new ones.[3]

The table below is a summary; the Eurostat methodology document is the authoritative source.[2]

Check each row against the Eurostat publication before you recode production data.[2]

1. Export your account list with the current NACE Rev. 2 or UK SIC 2007 code on each row.
2. Join it to Eurostat's NACE Rev. 2 → Rev. 2.1 correspondence table.[3]
3. Flag one-to-many rows, where one old class maps to several new ones. These need a human decision, usually from the company's website or its register filing.
4. Keep both codes during the transition. National registers and statistics move at different speeds; Germany, for example, runs WZ 2025 alongside WZ 2008.[4]
5. Re-run your ideal customer profile filters against the new codes, and compare account counts before and after.

Fictional example: A fictional coatings supplier targets NACE Rev. 2 class 25.61 (treatment and coating of metals). Under NACE Rev. 2.1 that work sits in 25.51 (coating of metals) or 25.52 (heat treatment of metals), and machining moves from 25.62 to 25.53.[2] In Rev. 2.1, 25.61 and 25.62 mean cutlery and locks and hinges, so a filter left on the old codes would pull in the wrong companies. The supplier reviews each one by hand, keeps both codes in its CRM, and updates its ICP filter so no accounts are silently dropped. This example is fictional and only illustrates the method.

• UK: Companies House records use UK SIC 2007, which is derived from NACE Rev. 2.[5] Don't assume a UK code matches a NACE Rev. 2.1 code.
• Ireland: check which NACE version each dataset uses. For the Irish manufacturing base, see our Irish manufacturing account research guide.

Activity codes are self-declared and often out of date. Use them to build a first cut. Then confirm each account with evidence: products on the website, permits (see the EU Industrial Emissions Portal guide), tenders and hiring. Our industrial ideal customer profile and prospect list maintenance guides cover that step.

Demand Range builds and maintains company-level industrial account lists with checked activity and the evidence for each row, mapped to the classification you use. Named contacts and outreach are separate scopes, not included by default.
