How is Istat asked about ATECO 2025?

Istat is asked about ATECO 2025 through the channels stated on the Istat website, in the dedicated ATECO section, and through the reporting channel in the statistical portal for survey users. Istat states that a dedicated mailbox was prepared for clarification requests about ATECO 2025, and that further information would be made available in the coming months for the full implementation of the classification and its correct interpretation.

This guide does not reproduce the mailbox address, because an address copied into a guide can become out of date, and the current address is the one stated on the Istat page itself. A reader should go to the Istat ATECO section, find the current contact channel stated there, and use that channel. A guide that reproduces a contact address risks misdirecting a reader after the address changes. A guide that points to the page where the address is published stays correct for longer.

What should a request contain?

A request should contain the question, the heading or code concerned with its version stated, and the description of the activity in the terms of the classification. A question about the meaning of a heading needs the code and the version, so that Istat can find the right note. A question about a correspondence row needs the old code with its version, and the new code or codes found, so that Istat can check the row. A question about an entry in a survey needs the survey context and the proposed code as shown in the portal, so that Istat can find the proposal. A question that gives only an activity name, without a code or a version, cannot be answered precisely, because the same name can sit under different headings in different versions. A question that gives only a code, without a version, cannot be answered with confidence for the same reason. Each question needs its own input, and a complete request gives all of them.

Question type	Asked through	Input needed
Meaning of a heading	Istat ATECO section, contact channel stated there	Code with version, note passage in question
Correspondence row	Istat ATECO section, contact channel stated there	Old code with version, new code or codes found
Survey entry proposal	Statistical portal reporting channel	Credentials, proposed code as shown in the portal
Register entry in general	Register that holds the entry	Identifying information stated by that register

The table above separates question types by channel and input. It states no timescale for a reply, because none was stated on the Istat page fetched for this guide. A reader should allow time for assessment, and should check the Istat page for any stated timescale before asking.

How should the activity be described in a request?

The activity should be described as carried out, in concrete terms, naming what is produced or what service is provided, and naming the prevailing activity where several activities are carried out. General terms, such as a sector name or a job title, are less useful than a description of the production process or the output, because the classification groups activities by production process and by the nature of the goods or services. A description that states only an intention, a market, or a customer type will match headings poorly. Which heading describes a specific activity is not stated in this guide. It states how to frame the description so that Istat can match it to the notes. A request that frames the activity well will get a precise answer. A request that frames it poorly will get a general answer, or a request for more information, and the check will take longer.

What should not be asked of Istat?

A reader should not ask Istat to decide tax, licensing, funding or collective agreement questions, because those questions belong to other bodies. Istat is responsible for the classification of economic activities. It answers questions about the classification, its structure, its notes, and its correspondence tables. It does not decide the other questions, and a request framed as if the code would decide them will be answered, correctly, as a statistical matter. Nor should a reader ask this site, or any guide, to determine a code. The classification, the tables and the routes are what guides describe. No register is held, and no entry is decided. A request for a determination about a specific unit should go to Istat or to the register that holds the entry, with the information listed in this guide ready.

Where the check ends

The check ends with the heading note that describes the activity in general terms, the correspondence row that links the versions, and the entry as confirmed by the register that holds it. Where the note, the row and the entry agree, the check is complete for statistical purposes. Where they disagree, the correction route for the register concerned is the next step. Where a question cannot be answered from the published material, the check ends with a clear statement of what could not be confirmed, and a request to Istat through the channel stated on its site. An unconfirmed check is a useful result. It prevents a wrong code from being copied forward as if it were settled.

Go to the Istat ATECO section for the current contact channel, send the code with its version and the activity described in concrete terms, and let Istat answer the classification question while the register confirms the entry. ”
