jansenfelipe/cpf-gratis
A compact PHP package for handling Brazilian CPF numbers. It makes it easy to validate CPF values, reject invalid documents, and add CPF checks to Laravel validators or any PHP project with minimal setup and no external dependencies.
Consider it when:
Look elsewhere when:
Executive summary: This package is a low-cost experiment to test CPF verification in Brazilian customer or seller flows. It can reduce manual checks and validate demand, but it is not a strategic KYC platform: it depends on an external government website, lacks official API guarantees, and creates compliance and security obligations. Approve a bounded pilot with legal/security review, manual fallback, and success metrics such as fraud reduction, conversion impact, and manual-review hours saved. Engineering: wrap it behind an adapter, rate-limit and monitor failures, minimize PII, and keep a clean replacement path to an official provider. Recommendation: pilot for back-office or low-risk use; do not make it the sole gate for regulated or high-volume onboarding.
