1 January 2027
APE codes switch over
The new APE code under NAF 2025 applies to every unit in the Sirene register, including micro-entrepreneurs.
What changes with NAF 2025
- The previous classification dated from 2008: NAF 2025 covers activities that have emerged since, such as intermediation platforms.
- The code still has five characters: four digits aligned with the European code, followed by a letter specific to France.
- The final letter changes between the old and the new code, for example 52.24A becomes 52.24G for port cargo handling.
- Some activities are grouped or split differently: a correspondence table is not always enough to move from one code to the other.
- According to INSEE, the new code does not create any right or obligation different from the old one.
To find a company's future code, the reference source is the Sirene register: enter its SIREN number on sirene.gouv.fr.
What the reform changes for your credit decisions
The NAF code is often used as a first filter: excluded sectors, credit limits by activity, default statistics. On 1 January 2027, these rules will have to apply to new codes. Six points to check:
RocketFin and NAF 2025
The sector is one of the signals taken into account, but the RocketFin score does not rely on the NAF code alone: it cross-checks over 100 data points from four sources to produce a 0-100 score in as little as 60 seconds, with an explainable PDF report and a recommended credit limit.
Frequently asked questions about the NAF reform
When does NAF 2025 take effect?
The new APE code under NAF 2025 applies from 1 January 2027 to every unit in the Sirene register. In 2026, the future code can be looked up for information, but only the current code applies.
Will APE codes change automatically?
Yes. INSEE assigns the new code based on NAF 2025, with no action required from the company. The future code can be looked up on sirene.gouv.fr with the company's SIREN number, and a review can be requested through INSEE's online form.
Why does the reform matter for credit teams?
Many credit policies rely on the NAF code: sector exclusions, credit limits, default statistics by sector. On 1 January 2027 these rules will need to be mapped to the new codes, and historical series will have a break.
Does the RocketFin score depend on the NAF code?
The sector is one of the signals taken into account, but the RocketFin score does not rely on the NAF code alone: it cross-checks over 100 data points from four sources (accounting, banking, legal and extra-financial) to produce a 0-100 score in as little as 60 seconds.
Where can I find official information?
On the INSEE website (NAF 2025 classification and Sirene register) and on sirene.gouv.fr to look up a company's future code.
