validate_cnpj

Active

declared in 0.1.0

Validate a Brazilian CNPJ (Cadastro Nacional da Pessoa Jurídica, the 14-character company tax ID) and look up the company registration: legal name (razão social), trade name, CNAE activity, address, registration status (situação cadastral), and partners (QSA). Checksum supports both the classic numeric format and the alphanumeric CNPJ introduced in 2026. Punctuation (12.345.678/0001-95) is accepted. Set skip_lookup to validate the checksum only.
