Question 1

Is the CNPJ generated by this tool valid?

Accepted Answer

Yes, the CNPJ number is mathematically valid. It is generated following the official verification digit calculation algorithm (modulus 11), which ensures it is accepted in forms and systems that have this validation. However, it is a fictitious number and does not correspond to a real company registered with the Federal Revenue.

Question 2

Can I use this CNPJ to open a company or issue invoices?

Accepted Answer

No. The purpose of the generator is strictly for software testing, studies, and filling out forms in development environments. The use of a fictitious CNPJ for commercial, tax, or fraudulent purposes is illegal.

Question 3

How does the CNPJ Generator work?

Accepted Answer

The tool randomly creates the first twelve digits of the CNPJ and then applies the calculation algorithm to determine the last two digits, which are the verification digits. This process ensures that the final number is structurally correct and valid.

Question 4

Is it safe to use this CNPJ generator?

Accepted Answer

Completely safe. The generation of the number occurs entirely in your browser (client-side), and no information is sent or stored on our servers. Your privacy and security are guaranteed.
