Test Your Application With Real Numbers of Your Clients' CNPJ
If you need to test your application with real numbers of your clients' CNPJ, you can download our CPF/CNPJ Validator app. With it you can:
Create CNPJ numbers for your clients, for them to use with the application or to test it. Check that the numbers you create are correct. You can enter the CNPJ number, and it will be checked by the application. If the number is wrong, it will be checked by the application, and you will be given the opportunity to correct it. You can enter more than one number and the app will check them all. Create your own valid numbers of your clients' CPF. You can choose the name, year, and month, and the numbers will be generated and checked by the app.
