Generate mathematically valid CNPJs with or without a mask, in batches, for use in system tests, integrations, registrations and homologation environments with no connection to real companies. No data is stored.
⚠️ The CNPJs generated are only valid from the mathematical point of view of the check digits. They do not represent real companies and do not consult official databases. Use only for testing, homologation environment and educational purposes only. Never use for fraud, opening accounts or real registrations.
