Object documentationAccess Key

 

A 44-digit key that uniquely identifies an electronic fiscal document (such as NF-e or CT-e).

 

When an electronic fiscal document is posted - incoming or outgoing, created manually by you or automatically by the system - the system generates the access key and displays it in the Nota Fiscal Writer, on the NF-e Data specifically for Nf-e or on the Electronic Doc Data tab for other electronic fiscal documents, such as CT-e.

You can use the access key when you communicate to the tax authorities about a particular electronic fiscal document.

Structure

The access key comprises the following elements:

  • Region of the document issuer

  • Year of document posting date

  • Month of document posting date

  • CNPJ number of document issuer

  • NF model

  • NF series

  • Nine-digit NF-e number

  • Random number

  • Check digit

The system displays the individual elements of the access key in the corresponding fields in the NF-e/CT-e Monitor. For more information, see Electronic Fiscal Document Data.
