Primary Identifier: We use Codice Fiscale (Tax Code) as the company ID for all Italian entities.For companies, the Codice Fiscale (11 digits) is typically identical to their Partita IVA (VAT number).
Understanding Italian Company Identifiers
Codice Fiscale (Tax Code)
- 11 digits for companies:
01654010345
- 16 alphanumeric for individuals:
RSSMRA85M01H501Z
- Universal fiscal identifier required for all administrative interactions in Italy
Partita IVA (VAT Number)
- 11 digits:
01654010345
- Required for commercial activities and VAT transactions
- For companies (SRL, SPA, etc.): Usually identical to Codice Fiscale
- For individuals (sole proprietors): Always different from personal tax code
CCIAA + REA Code
- CCIAA: Chamber of Commerce provincial code (2 letters) - e.g.,
TO (Torino), MI (Milano), RM (Roma)
- REA Code: Economic and Administrative Register number (1-7 digits) - e.g.,
1239673
- Together they form a unique provincial identifier:
TO1239673
Search Capabilities
Search automatically detects the identifier type and returns appropriate results:
| Search Pattern | Format | Examples | Match Type | Results |
|---|
| Company Name | Text string | Barilla
Zona Web | Fuzzy match | Up to 10 results |
| CCIAA + REA | 2 letters + 1-7 digits | TO1239673
TO 1239673
RM1503238 | Exact match by province | 1 result |
| REA Only | 1-7 digits | 1239673
12345 | Cross-province + name search¹ | Multiple results |
| Partita IVA | 11 digits | 01654010345
IT01654010345 | Exact match | 1 result |
| Codice Fiscale (Company) | 11 digits | 03943150270 | Exact match | 1 result |
| Codice Fiscale (Individual) | 16 alphanumeric | MHJKST95E15Z100G | Exact match | 1 result |
¹ REA numbers are unique within a province but can exist in multiple
provinces. Searching by REA only (without CCIAA) performs both a
cross-province REA search and a company name search simultaneously, then
combines and deduplicates the results. This ensures you get both exact REA
matches across all provinces and relevant name matches.
// Company name search
search('Barilla'); // Returns up to 10 matches
// Provincial register search
search('TO1239673'); // CCIAA=TO, REA=1239673 → 1 exact result
search('TO 1239673'); // Space-separated also works
// Cross-province REA search (combines REA + name search)
search('1239673'); // Returns REA matches + name matches, deduplicated
// Tax/VAT identifier search
search('01654010345'); // 11 digits → Partita IVA/Codice Fiscale
search('MHJKST95E15Z100G'); // 16 chars → Individual Codice Fiscale

Activity Classifications
Italy provides comprehensive activity classification through multiple nomenclatures with sophisticated processing logic:
ATECO Classifications (Italian Standard):
- ATECO2025: Latest Italian classification standard
- Primary: The main business activity (first code returned)
- Secondary: Additional business activities (remaining codes)
- ATECO2022: Previous Italian classification standard
- Primary: The main business activity (first code returned)
- Secondary: Additional business activities (remaining codes)
All ATECO codes include English descriptions derived from official mappings and translations.
Single-Value Classifications:
- RAE: Italian Economic Administrative Register classification (single code)
- SAE: Italian Statistical Administrative classification (single code)
- SIC: US Standard Industrial Classification (single code)
AI-Mapped International Classifications:
- ISIC: International Standard Industrial Classification (AI-inferred, single code)
- NACE: European standard classification (AI-inferred, single code)
ISIC/NACE Generation Priority:
- Primary ATECO2025 code (if available)
- Primary ATECO2022 code (if ATECO2025 unavailable)
- RAE code (if no ATECO codes available)
- SAE code (if no other codes available)
The AI uses semantic analysis to map the highest-priority available classification to international standards, ensuring accurate cross-referencing while maintaining single, authoritative ISIC/NACE codes.
Note: ATECO code lengths vary from 2-6 digits depending on the company’s registered activities and data availability in Italian registers. There is no universal logic differentiating code length based on primary vs secondary status.
