Learn more about WebCatalog Desktop

CPFHub.io is for businesses and developers that need to check Brazilian individual and company registration details during customer onboarding, account setup, hiring, or fraud-prevention workflows. Its API returns CPF-linked information such as a person’s name, gender, and date of birth, and can check a CPF’s registration status directly with Brazil’s Receita Federal, returning a control code and proof of the result. CNPJ lookups return company details including registration status, business activity, address, and partners; these records come from the Receita Federal’s public dataset, which is updated monthly rather than queried in real time. You can make individual lookups through the API or use the dashboard to check records and process lists from CSV or TXT files. Batch lookups support up to 10,000 CPFs or CNPJs per request. The dashboard also provides a searchable lookup history with CSV or JSON export, while the API is intended for integrating checks into an existing system. This may suit teams that need Brazilian CPF or CNPJ data in their workflows; it is not a general-purpose identity database.
