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

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.
Example Searches: 
// Company name search
search('Barilla'); // Returns up to 10 matches

// Provincial registry 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:
  1. Primary ATECO2025 code (if available)
  2. Primary ATECO2022 code (if ATECO2025 unavailable)
  3. RAE code (if no ATECO codes available)
  4. 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 registries. There is no universal logic differentiating code length based on primary vs secondary status.

Example: Barilla G. E R. Fratelli SPA

  "activities": {
    "ATECO2025": [
      {

        "isAIInferred": false
      }
      // ... additional secondary codes
    ],
    "ATECO2022": [
      {
        "code": "1073",
        "description": "Manufacture of farinaceous products",

        "isAIInferred": false
      }
      // ... additional secondary codes
    ],
    "RAE": [
      {
        "code": "417",
        "description": "PASTE ALIMENTARI",
        "isAIInferred": false
      }
    ],
    "SAE": [
      {
        "code": "430",
        "description": "Imprese produttive",
        "isAIInferred": false
      }
    ],
    "SIC": [
      {
        "code": "2098",
        "description": "Macaroni, spaghetti & other noodle mfrs",
        "isAIInferred": false
      }
    ],
    "ISIC": [

    "NACE": [

        "description": "Manufacture of macaroni, noodles, couscous and similar farinaceous products",
        "isAIInferred": true
      }
    ]
  }
}
In this example:
  • Primary activity: “1073” (Manufacture of farinaceous products) from ATECO2025
  • ISIC/NACE generation: Based on primary ATECO2025 code “1073”
  • Secondary activities: Multiple additional ATECO codes for various installation services
  • Registry codes: Single values for RAE (pasta manufacturing) and SAE (productive enterprises)
