Notfy queries official tables through the tax issuer to fill in records faster and with fewer errors.

When to use

When registering the issuing company, building tax profiles and entering invoice items.

Available lookups

Fill in by CNPJ

1

Save the CNPJ

The button reads the CNPJ (Brazilian company tax ID) already saved in the integration. If there is none, “CNPJ not registered” appears.
2

Click Fill in by CNPJ

Notfy queries the Receita (Brazilian federal revenue service) through the tax issuer and fills in the fields.
3

Review and save

The message “Data filled in by Receita” asks you to review it. If the company’s registration status is not active, the notice reports the status.
The tax regime filled in is only a suggestion (MEI or Simples). Confirm with your accountant before issuing.
Lookups depend on the tax issuer being available. If they fail, the lists appear empty and you can type the code manually; Notfy marks that code as “not verified”.
