TypeScript is a language for application scale JavaScript development

validator‑brazil is a lightweight, zero‑dependency TypeScript library that validates Brazil’s main identifiers—CPF (individual tax ID), CNPJ (company tax ID, including the new alphanumeric format effective July 2026), and CEP (postal code). It’s aimed at developers building Node.js or browser applications who need simple, reliable validation of Brazilian numbers without pulling in extra packages.
