Tax ID generator

Generate valid-format tax IDs for testing and QA, in one click.

Open the popup and get a ready-to-use tax ID for Portugal, Italy, Spain and Germany, with separate cards for employees and companies.

Supported IDs:
• Portugal: NIF (person and company)
• Italy: Codice Fiscale (person) and Partita IVA (company)
• Spain: DNI (person) and CIF (company)
• Germany: Steuer-IdNr (person) and Steuernummer (company)

How it works:
• Click a card to copy its tax ID to the clipboard.
• Click the refresh icon on a card to generate a new one.

Every number follows the format and check-digit rules of its country, so it passes typical form and API validation. The numbers are randomly generated and are not registered with any tax authority. Use them for mock data, test environments and demos only, never for real filings or identification.

No account, no tracking, and no special permissions.
