How is rectification of a future APE code requested?

Rectification of a future APE code is requested through Sirene, using the tool that Service Public describes for consulting and rectifying the new APE code. Service Public states that it is possible to consult the new APE code and to request a possible rectification, by informing the SIREN number in the tool on Sirene.gouv.fr. The request asks INSEE to review the prepared code. It does not change the code by itself. INSEE reviews the request and decides the entry, as the institute that holds the nomenclature and assigns the code.

This guide describes the route in general terms from the Service Public page. It does not determine any reader’s code, and it does not promise an outcome for any request.

What does the request ask INSEE to review?

The request asks INSEE to review whether the prepared APE code matches the main activity exercised by the unit. The prepared code is based on the information INSEE holds. Where the main activity has changed, or where the information held does not describe the main activity correctly, the prepared code can be wrong. The request is the way to put the correct description before INSEE. A request should therefore state the main activity as exercised, in terms that match the nomenclature headings, rather than stating only that the code feels wrong. The nomenclature on the INSEE website shows the headings and their titles. The request is stronger where it points to the heading that describes the main activity, because INSEE can then check that heading against the information it holds. This guide does not state which heading describes any specific activity. That is a matter for the INSEE nomenclature and for INSEE’s review.

Step	Action	Who decides
Check	Enter the SIREN number in Sirene and read the prepared code	INSEE, through the prepared entry
Request	Ask for rectification through the Sirene route stated by Service Public	Reader makes the request
Review	INSEE reviews the request against the information held	INSEE
Entry	Sirene shows the code after review	INSEE, through Sirene

The table above shows the sequence as described by Service Public. It states no timescale for review, because no timescale was stated on the Service Public page fetched for this guide. A reader should check Sirene for the current position of a request, rather than assuming a date.

What identifiers are needed?

Service Public states that the Sirene procedure requires the SIREN number and the identifiers for the ProConnect service, and that people without a ProConnect account can request a change via a paper form. That statement comes from the Service Public notice about the future APE code, as recorded in the research for this site. This guide does not reproduce the form, and it does not state a processing time, because neither was stated on the Service Public page fetched for this guide. A reader who cannot use the online route should use the paper route stated by Service Public, and should follow the instructions on the Sirene site itself. The identifiers and the form belong to the official procedure. This site does not collect identifiers and does not submit requests for any reader.

What happens if no request is made?

If no request is made, the prepared code stands as the entry that will apply from 1 January 2027 (FIXED), according to Service Public, which states that all companies and establishments will have their codes modified according to NAF 2025 from that date. Silence is therefore not neutral. It leaves the prepared entry in place. That is why Service Public presents the check and the rectification route together: the check lets a reader see the prepared code in advance, and the rectification route lets a reader ask for a review before the new code applies. A reader who checks late, or who does not check, may still be able to raise the matter after the date, but this guide does not assert a post date route, because no post date route was stated on the pages fetched for this guide. The current route is the one stated by Service Public, and the current position should be checked in Sirene.

What does rectification not do?

Rectification does not decide tax, licensing, funding or collective agreement questions. It asks INSEE to review a statistical entry. Other authorities apply their own rules to the entry they hold, and a corrected APE code does not by itself change any decision made by another authority. The classification remains statistical in character, as the EUR-Lex summary states for the European legislation. The entry for a specific unit is confirmed with INSEE or through Sirene. This site holds no register and decides no entry.

Check the prepared code in Sirene, ask for review through the Sirene route where it does not match the main activity, and let INSEE decide the entry that Sirene then shows. ”
