About CNPJ and How It Works
What is CNPJ: The National Registry of Legal Entities (CNPJ) is a unique number that identifies a legal entity in Brazil. It is issued by the Federal Revenue.
CNPJ Structure: The CNPJ has 14 digits in the format XX.XXX.XXX/XXXX-XX, where the first 8 identify the company, the next 4 the branch (0001 for headquarters) and the last 2 are verification digits.
How to use generated CNPJs: Ideal for system testing, software development, demonstrations and form validation. All follow the official validation algorithm.
