🎫 Tax ID / VAT Number

A tax identification or VAT number is a government-issued code identifying an entity or person for taxation (EIN, VAT, TIN, UTR). It validates entity existence, links invoices and payments to a legal party, and exposes cross-border trade and shell-company VAT fraud.

Format: EU VAT = 2-letter country code + up to 12 alphanumerics (e.g. DE123456789, IE1234567FA); US EIN = NN-NNNNNNN; each country has its own checksum (e.g. Italian VAT Luhn-like mod check)

📡 How it is collected

• Invoices and commercial contracts
• VAT registration certificates
• Company registry filings
• Import/export customs declarations
• Website legal/imprint pages
• Procurement records
