Brazilian test data for developers

What DevBR Kit is

DevBR Kit is a set of generators and validators for Brazilian documents, built for people who write and test software. If you are integrating with a Brazilian system, you will quickly run into IDs such as the CPF (the individual taxpayer number) or the CNPJ (the company registration number), each with its own check-digit rules. Here you can create fictitious CPFs, CNPJs (including the new alphanumeric format), driver's licence (CNH) numbers, voter IDs, PIS/PASEP, RENAVAM vehicle codes, licence plates and more, all with valid check digits. Use them for test fixtures, seeding staging databases, form validation tests or demos, or paste a list of values to check which ones are valid and why.

Use it responsibly

The numbers follow the official algorithms but do not belong to real people or companies, and they are meant for software testing only. Do not use them to sign up for real services or get around identity checks: using fake documents is a crime in Brazil. Read the Terms of Use and learn more about the project.
