What is a CPF?
CPF (Cadastro de Pessoas Físicas) is the Brazilian individual taxpayer identification number, similar to the US Social Security Number or the UK National Insurance Number. It has 11 digits in the format XXX.XXX.XXX-XX, where the last two digits are check digits calculated by a mod-11 algorithm. Every Brazilian citizen and resident has a unique CPF, used for tax filing, financial transactions, employment, healthcare and government services.
When to use a fake CPF
International fintech, payments, KYC, and identity verification teams working with Brazilian customers need CPF test data that behaves like real CPFs in validation pipelines. FakeForge generates CPFs that pass mod-11 checksum but do not belong to real people. Use cases: Stripe Connect onboarding for Brazilian merchants, Adyen payment method testing, customer onboarding flows for Brazilian markets, sanctions screening pipelines, and any QA scenario that exercises CPF validation logic.
REST API for automated testing
Use the REST API to seed test databases and run integration tests:
# Generate 100 valid CPFs
curl "https://fakeforge.com.br/api/generate?type=cpf&quantity=100"
# Bulk export as SQL for database seeding
curl -X POST "https://fakeforge.com.br/api/generate" \
-H "Content-Type: application/json" \
-d '{"type":"cpf","quantity":1000,"format":"sql"}'Free tier: 100 requests per day, up to 10,000 CPFs per call. No signup, no API key required. For higher volumes or dedicated rate limits, paid plans start at BRL 29 per month.
Compliance and safety
Using real CPFs in development or staging environments violates the LGPD (Brazilian data protection law) and exposes companies to fines up to BRL 50 million per incident. FakeForge CPFs are generated on demand and not stored, so there is no risk of leaking real personal data through test fixtures, screenshots, or log files. Safe for CI/CD pipelines, shared staging databases, and customer demo environments.
