What Is This Tool?

The CNPJ (Cadastro Nacional da Pessoa Jurídica) is the official 14-digit tax identification number issued to Brazilian businesses and organizations in the format XX.XXX.XXX/0001-XX.

Why It Matters

Testing B2B invoicing, simulated invoice issuance (NF-e), and payment integrations requires valid corporate registration data.

Developer Tip
Use the 'Copy JSON' button to quickly paste mock objects directly into Jest, Cypress, or Playwright test suites.
