Registro Imprese — the Italian company register
The document most onboarding teams collect for an Italian company carries a printed line saying it is not a certificate. The Registro Imprese is the Italian business register, held by the Chambers of Commerce and built on Article 2188 of the Civil Code. It is where an Italian counterparty’s legal form, registered office and directors live. But it has two tiers of legal effect, two document types of different evidentiary weight, and an activity-code set the state rewrote underneath every file in 2025 — and a KYB process that treats it as one flat lookup gets all three wrong.
1. What the Registro Imprese is, and who holds it
Article 2188 of the Civil Code creates the register. Article 8 of Law 580 of 29 December 1993 puts the register office inside each provincial Chamber of Commerce, and Presidential Decree 581 of 7 December 1995 is the implementing regulation. Article 7 of that decree states the structural point plainly: the register is single and includes the special sections. One national register, operated province by province, on a shared information system.
A giudice del registro designated at the tribunal oversees the office’s registrations, and the Ministry of Enterprises, in agreement with the Ministry of Justice and after consulting the national union of chambers, issues directives so the register is kept uniformly nationwide. Provincial variation is procedural, not substantive.
It is an identification and publicity register, not an authorisation one. Whether the counterparty may carry on a regulated activity is answered by the supervisory registers — the OAM registers for agents and crypto operators, or the Banca d’Italia albi. A KYB file that stops at the visura has checked existence, not permission.
2. Who is in it — and the branch trap for foreign firms
Article 7(2) of Decree 581/1995 lists who is entered: the commercial entrepreneurs of Article 2195 of the Civil Code, the companies of Article 2200, consortia under Article 2612 and consortium companies under Article 2615-ter, European economic interest groupings, commercial public bodies under Article 2201, and companies subject to Italian law under Article 25 of Law 218/1995. Then, separately, agricultural entrepreneurs (Article 2135), small entrepreneurs (Article 2083) and società semplici (Article 2251).
That last group matters because Article 7(3) sends them to the special sections, which do not carry the same legal effect. Artisan enterprises in the regional artisan rolls are additionally annotated in a dedicated special section under Article 7(4).
For a cross-border payments firm the provision to read twice is Article 9(2)(b), which obliges entrepreneurs with their principal seat abroad who open local units in Italy to file with the REA. With Article 2197 of the Civil Code on secondary seats, the shape is familiar: serving Italy under the freedom to provide services leaves no register footprint; a branch or local unit creates one. A foreign firm you cannot find may simply be passporting — one with an Italian branch and no register entry is a finding, not a data gap.
3. Ordinary section versus special sections — the effect gap
This distinction silently breaks Italian KYB. The ordinary section carries the declarative publicity of Article 2193 of the Civil Code: registered facts are opposable to third parties, who cannot plead ignorance of them. A special section was designed, for most categories, as certification and record-keeping rather than that full third-party effect — agricultural entrepreneurs were later given declarative effect by separate legislation. Article 24(6) of Decree 581/1995 shows the consequence: the certificazione anagrafica of a special-section registration attests only name, trade name, object and seat.
| Tier | Typical occupants | Effect of registration | What the certificate attests |
|---|---|---|---|
| Ordinary section | SpA, Srl, Snc, Sas, cooperatives, consortia, EEIGs, commercial public bodies | Declarative publicity under Art. 2193 CC — opposable to third parties | Full registered content, including directors and powers |
| Special sections | Small entrepreneurs, società semplici, agricultural entrepreneurs, artisan annotation | Principally certification and record-keeping; agricultural entrepreneurs by later law carry declarative effect | Name, trade name, object, seat (Art. 24(6) DPR 581/1995) |
So for a società semplice or a small entrepreneur, do not expect the register alone to evidence representation powers to the standard you would accept for an Srl. Collect the constitutive documents.
4. The REA, and why the numbers are not interchangeable
Article 9 of Decree 581/1995 establishes the repertorio delle notizie economiche ed amministrative — the REA — at each register office, implementing Article 8(8)(d) of Law 580/1993. Article 9(3) defines it by subtraction: the economic and administrative notices declarable to the Chamber of Commerce under the older chamber legislation, excluding anything already registered in the Registro Imprese and its special sections. An Italian counterparty therefore carries several identifiers answering different questions.
| Identifier | Shape | What it identifies | KYB use |
|---|---|---|---|
| Codice fiscale | 11 digits for entities | The entity in the tax system; doubles as the register registration number for companies | Primary key; stable across name and seat changes |
| Partita IVA | 11 digits | VAT registration | Often equal to the codice fiscale but not always; an entity can have one and not the other |
| Numero REA | Province code + sequence, e.g. MI-1234567 | The administrative position at one chamber | Province-scoped; never use it as a national key |
5. Visura versus certificato — the line most files get wrong
Article 23 of Decree 581/1995 makes the protocol, the register and the document archive public, and provides for consultation from remote terminals through the chambers’ information system, including a printout bearing the words “visura senza valore di certificazione” — an extract without certification value. Article 24 deals separately with certificates, issued on ministerially approved models, and with copies from the document archive at no more than administrative cost.
The two are not grades of the same thing. The visura is an information product: complete, current, cheap, and explicitly labelled as not certifying anything. The certificate is the instrument that certifies. Both draw on the same data, so for a risk decision the visura is usually the right document. The error is downstream: a file that must evidence the company’s status to a supervisor, a court or a correspondent, resting on a document that says on its face that it does not certify.
Two mechanics belong in the procedure. Article 11(8) fixes the timetable — registration without delay and in any case within 10 days of protocolling, halved for electronic filings. Article 8 provides that filed deeds are archived as images, the image substituting the original for all legal purposes. A same-week Italian corporate change is normally visible, and the deed itself is retrievable as a copy.
6. ATECO 2025 — the codes moved underneath your files
Italy’s activity classification was replaced. ATECO 2025 entered into force on 1 January 2025 and was adopted operationally from 1 April 2025, coordinated between the national statistics institute, the chamber system and the tax administration. It is the Italian implementation of NACE Rev. 2.1, hierarchical to six digits across sections, divisions, groups, classes, categories and sub-categories. The statistics institute publishes bidirectional correspondence tables and an operational reclassification table from the previous ATECO 2022 set; a 2026 update changed correspondence relationships only, leaving structure and descriptions alone. Reclassification in the register ran automatically from 1 April 2025, extracts showed both new and prior codes through a transitional period, and a free online service let businesses correct a bad automatic mapping.
Three consequences for a payments firm:
- Any stored Italian ATECO code captured before April 2025 is a dead vocabulary. A merchant-category or risk-tier mapping keyed on it is keying on a code the register no longer issues.
- An automatic remap is not a business decision. Where an old code split across several new ones, the automatic assignment picked one — so a code refreshed today can differ from the same firm’s 2024 extract with nothing having actually changed.
- The mapping is published. The correspondence tables are the migration path, and they belong in the source system rather than in an analyst’s head.
Italy is the third EU register in two years to renumber activity codes on the back of NACE Rev. 2.1, alongside the Belgian NACE-BEL 2025 conversion and the French NAF 2025 change. If your KYB model holds one activity-code field per country, it now needs a vintage alongside it.
7. The administrator’s PEC — a new field on the extract
Italian companies have long had to register a domicilio digitale, the certified electronic mail address (PEC) for legally effective communications. Article 1(860) of Law 207 of 30 December 2024, the 2025 budget law, extended the obligation to company administrators, amending the digital-agenda decree-law of 2012.
The rule was then narrowed. Decree-Law 159 of 2025, Article 13, in force from 31 October 2025, confined the duty to the sole administrator, the managing director or, failing those, the chair of the board, in capital companies, cooperatives and consortium companies — excluding partnerships and other office-holders — and set the compliance date at 31 December 2025. It also fixed a point that matters for verification: the administrator’s digital domicile cannot coincide with the company’s.
So capital-company extracts pulled after that date should carry a personal PEC for the named administrator, distinct from the company’s; its absence on a recently-updated extract is a cheap data point about the counterparty’s housekeeping. The company PEC remains the correct channel for legally effective service — a register field, not a courtesy contact.
8. Three scenarios from an onboarding queue
A merchant whose activity code changed without the merchant changing. A Milan wholesaler onboarded in 2023 sits in a low-risk tier keyed to its ATECO 2007 code. A 2026 review pulls a fresh visura; the code is different and maps to a tier the firm holds no policy for. The rule that applies is not an AML one — it is the April 2025 automatic reclassification. The analyst checks the published correspondence table, confirms the new code is the expected image of the old one, records both vintages, and leaves the tier alone. If there is no correspondence path, that is a genuine activity change and goes to review. One case is a data migration; the other is a customer telling you something.
A società semplice presented with a visura as proof of signing authority. A prospective counterparty sends an extract showing a partner as representative. Because the entity sits in a special section, the register line does not carry the Article 2193 declarative effect an ordinary-section registration would, and the certificate for that section attests only name, trade name, object and seat. The analyst does not reject the counterparty; they request the constitutive deed and the powers it confers, and record why the register alone was insufficient.
A foreign EU payments firm with an Italian address and no register entry. Two readings: it serves Italy under the freedom to provide services and the Milan address is a group office; or it operates through an establishment and should be registered under Article 2197 of the Civil Code and declared to the REA under Article 9(2)(b). The analyst tests which by asking what the Italian address is. Branch versus freedom of services is the whole question, and the register is the evidence.
9. What to do, today
- Make the codice fiscale the key. Demote the REA number to a display field.
- Add a vintage to every stored ATECO code and run the published correspondence tables over anything captured before April 2025 before it drives a risk tier.
- Record which section the entity sits in. Ordinary or special tells the analyst whether the register settles representation powers.
- Decide, once, when a certificate is required rather than a visura — the exception, for files that must evidence status to a third party.
- Check the administrator PEC on capital-company extracts refreshed after 31 December 2025; it must differ from the company’s.
Is a visura camerale acceptable evidence for a KYB file?
For the risk decision, yes — it carries the same content as a certificate and is current. But it bears the printed wording that it has no certification value under Article 23 of Decree 581/1995, so where the file must evidence status to a supervisor, a court or a correspondent, obtain the certificate under Article 24 instead.
What is the difference between the REA number and the registration number?
For companies the register registration number is the codice fiscale. The REA number is the administrative position at one provincial chamber, written as a province code and a sequence. An entity that transfers its seat to another province takes a new REA number and keeps its codice fiscale.
Does a foreign company serving Italian customers have to be in the Registro Imprese?
Only where it has an establishment. A secondary seat with stable representation is registered under Article 2197 of the Civil Code, and an entrepreneur based abroad opening local units in Italy must declare them to the REA under Article 9(2)(b) of Decree 581/1995. Pure cross-border services create no entry.
Why did our Italian merchant’s ATECO code change on its own?
Because ATECO 2025 replaced the earlier classification from 1 January 2025 and was adopted operationally from 1 April 2025, with register entries reclassified automatically. Extracts showed old and new codes side by side during the transition, and firms could correct an incorrect automatic mapping through a free online service.
Does the Registro Imprese tell us whether a counterparty is authorised?
No. It is an identification and publicity register. Authorisation to carry on a regulated activity is evidenced by the relevant supervisory register or albo, and a KYB file that relies on the business register alone has verified existence rather than permission.
