What Is the CNPJ API?
The CNPJ (Cadastro Nacional da Pessoa Jurídica) is Brazil's national registry run by Receita Federal. Every establishment carries a 14-character number; from mid-2026, new roots become alphanumeric.
There is no official free CNPJ REST API. Receita Federal publishes free monthly bulk files: split ZIPs of semicolon-separated CSVs with encoding quirks, which you download, parse and host yourself. The web lookup sits behind a CAPTCHA, and the only official API, SERPRO's Consulta CNPJ, is paid. Popular free endpoints are third-party projects built on the same bulk files.
CompanyData does that heavy lifting for you: 29M+ Brazilian records with razão social, nome fantasia, situação cadastral, natureza jurídica, CNAE classification and partner details, enriched with contact data, always current, in one REST API that also covers 200+ other countries.

Frequently Asked Questions
The 14-character Brazilian registry number: an 8-character root, a 4-character establishment code and 2 numeric check digits. From July 2026 new roots may contain letters; existing numbers stay unchanged. CompanyData records carry the CNPJ as the registration number.
Brazilian records are classified with CNAE, which follows the international ISIC structure. Every CompanyData record carries SIC and NACE industry codes as filterable fields, so Brazilian businesses slot into the same industry filters you use for every other country.
The official bulk files refresh monthly. CompanyData updates continuously from official and verified sources, so lookups reflect recent registrations and status changes without waiting for the next ZIP drop.
