CNPJ Generator
The CNPJ (Cadastro Nacional da Pessoa Jurídica) is the registration of companies and organizations in Brazil. This generator creates valid CNPJ numbers that follow the official algorithm but don't belong to real companies.
Our CNPJ generator is perfect for:
- Developers testing business systems
- Creating test data for financial software
- Validating business registration forms
CNPJ Structure
The CNPJ has 14 digits organized as follows:
- 8 digits for the company's base number
- 4 digits to identify the branch (0001 for headquarters)
- 2 verification digits

The CNPJ replaced the old CGC (Cadastro Geral de Contribuintes) in 1998, as part of the modernization of the Brazilian tax system.
